Abstract

In this work, the properties of a composition based on synthetic rubber ethylene-propylene ter-polymer and polymers with functional groups of the mixture are studied. Low efficiency of some compositions based on ethylene and propylene copolymer limits their use in the production of tires and rubber products. Therefore, we conducted a study to improve the disadvantages of SREPT-60 using butyl rubber + choro polyisoprene + butadiene-nitrile + butadiene styrene rubber and adding a plasticizer to the composition = α, methacrylate-(bis-diethylene glycol phthalate) -(btegf-9) The data obtained showed that a number of its indicators of rubber based on them were improved. Tear resistance, resistance to repeated stretching increased, adhesion of the composition to metal, chemical resistance increased, the degree of swelling in benzene and gasoline-benzene mixture decreased. Compositions based on the mixture SREPT-60 using butyl rubber + choro polyisoprene + butadiene-nitrile + butadiene styrene rubber and adding a plasticizer to the composition = α, methacrylate-(bis-diethylene glycol phthalate) -(btegf-9) +Dioctyl phthalate: (70:20:10) have high resistance to swelling in an aggressive environment (Benzene, gasoline, alcohol, acid, oil, etc.) mixture.

Introduction

Preparation of BTFR-based nanocomposites.

Several authors [1,2,3,4] used laboratory rubber mixers as the research methodology [5,6,7,8] to prepare nanocomposites. First, BTFR BSK was plasticized in Banbury for 2 minutes to obtain rubber nanocomposites. In this work, a mill was used, which is used to obtain nanoparticles Then, the nanofiller selected in 1, 3, or 5 parts per hour was added to the plasticized BTFR and mixed in the same mixer for 1 minute. This compound was mixed with ZnO as an activator and SC as a lubricant for 0.5 minutes. Then, the stabilizers (TMQ, IPPD, and ozone wax) were combined for another 0.5 minutes [9,10,11,12,13,14] The rubber nanocomposites were kept in an oven with air circulation for 70 hours at a temperature of 70 ° C to study the effect of thermal aging [14,15,16,17,18].

Modification of Butadiene terephthalate rubber with functional groups [19,20,21,22,23,24,25].

Manufacturers of general-purpose synthetic rubbers have devoted considerable effort to equipping such rubbers with chemically functional groups along the polymer backbone. The goals have ranged from improving green strength and tack to creating sites for new forms of crosslinking, grafting, antioxidant activity, and even pharmacological properties. The usual route to such functionalisms is to incorporate small amounts of the monomer carrying the desired group during polymerization. However, polymerization with different functional groups would be expensive, so only a cheap reagent must be used to macro modify elastomers with entirely new physical properties. If we use these polymers outdoors, then the rubber needs to be protected from sunlight, and most types of these polymers have flammable properties [5], although additives can reduce both the modification and the flammability properties [26,27,28,29,30]. used for casings in construction, as connectors in automotive manufacturing, and household applications, such as shower heads or irons. It is also found incorporated into toothbrush fibers and false eyelashes and is used in the keycaps of some high-end computer keyboards [31,32,33,34,35,36]

Yarn can also be made from PBT. It has a similar natural elongation and can be incorporated into sportswear, meaning that PBT is at the forefront of materials used in the production of swimwear in chlorinated waters. In addition, recent studies have shown that BTFR [37,38,39,40,41,42] is more durable than PET-based fabrics. had superior characteristics [42,43,44,45,46,47,48].

Method

For the modification of the Butadiene terephthalate rubber, we used astragalus for the first time. It looks like this:

The astragalus grown in the Nakhchivan region of the Republic of Azerbaijan was collected from the seeds collected from the upper and middle mountainous areas, mainly around the villages of Kalaki and Dirnis.

Astragalus (in Azerbaijan it is called Gavan) is a perennial herb 15-35 cm high, stem 4-20 cm long, elongated and erect or erect, reddish. Except for the inner side of the crown, all parts of the plant are covered with whitish or yellowish hairs. The color of the stems is brown-gray, the leaves are gray-green, and the flowers are yellow. It is a deciduous shrub, 20 cm high, with dense branches forming a cushion, prickly leaves, all parts covered with thin, weak hairs. The leaves are 8–12 mm long, feather-shaped, contiguous to half of the stem, linear-lanceolate. The leaves are 6-9 pairs, elliptic or oblong-ovate, 10 mm long, with sharp tips. It is bare above, sparsely or densely hairy below. The flowers form 2-3 short clusters in the axils of the leaves. Inflorescences are flat sepal-shaped and up to 13 mm long. The calyx is 10–16 mm long, tubular, thick, short, white hairy. The teeth are serrated and greenish. Its crown is up to 13 mm long. The sail is 7-8 mm wide and oblong-elliptical. The boat is shorter than the wing. Females are elongated, downy hairy, up to 16 mm long, and the stem is bare columnar. Beans are sessile, oblong, sharp, silky white hairy, single-celled, manyseeded. It blooms in June-July.

When the composition of Astragalus used in the research is analyzed, its chemical composition is Selenium 1.5mg%. There are macro and microelements (calcium, silicon, aluminum, iron, magnesium, cobalt, zinc, copper, manganese, molybdenum, chromium).

As a result of the analysis, it was determined that astragalus is compatible with butadiene terephthalate and can form a composition with it in different proportions. However, it was determined that the best result is obtained when the astragalus component in the composition is 10 parts by mass. Considering all this, we aim to improve the physical and mechanical properties of polybutadiene terephthalate. We took the amount of astragalius as 10 parts by mass. The indicators obtained as a result of the report are shown in Figure 1, Figure 2, Figure 3, Figure 4, Figure 5, Figure 6 and Figure 7

Rubber Mixture Based on BTFR and Astragalus

Based on BTFR and astragalus, using the flow index of mixtures, we adopt the optimal recipe shown in Table 1

Based on this recipe, after preparing a rubber mixture for 12 minutes in a laboratory roller at a temperature of 90 ^oC and vulcanizing it in a vulcanization press at a temperature of 155^oC for 25 minutes, the physical and mechanical properties of the vulcanizate obtained were determined and the results are given in Table 2

The presence of functional groups formed by using astragals in the polymer can be clearly seen in Figure 9, which is confirmed by IKS-analysis. so it can be safely said that some of the properties of this polymer can be eliminated by modifying it with astragals.

In order to satisfy the chemical stability of the obtained polymer astragalus composition vulcanizate in aggressive environments, we determined the physical and mechanical properties of the vulcanizates by vulcanizing the rubber mixture we prepared in the laboratory at a temperature of 155°C for 15 minutes in accordance with the recipes we accepted (Table 3).

Results

1. By modifying polybutadiene terephthalate with astragalus, it was determined how the modification process affects its mechanical properties.

3. The ozone resistance of the received resins showed that they are chemically very stable. Taking this into account, the offered rubbers can be used in the preparation of products that are resistant to ozone, oil, and gasoline and can work in aggressive environments.

4. As a result of scientific research, it has been proven that resins based on polybutadiene terephthalate and astragalus nanomaterial can be a special-purpose product. These rubbers can work in a wide range of temperatures and different climates. Ours is a Polybutylene Terephthalate (PBT) based rubber that can be used for general-purpose optical cable.

5. The proposed composition allows to significantly increase the strength of the connection of rubber with metals (steel-3, brass), to increase the resistance to gasoline and to improve the tensile strength index.
