What is the main component of rubber? The main component of rubber

The details are as follows:

Natural rubber is made from latex, and some of the non-rubber components contained in the latex remain in the solid natural rubber. Generally, natural rubber contains 92%-95% of rubber hydrocarbons, while non-rubber hydrocarbons account for 5%-8%. Due to different manufacturing methods, different origins and even different rubber picking seasons, the proportion of these ingredients may be different, but basically within the range.

Protein can promote the vulcanization of rubber and delay aging. On the other hand, protein has strong water absorption, which can cause moisture absorption and mildew of rubber, decreased insulation, and protein also has the disadvantage of increasing thermogenesis.

Acetone extract is a number of high-grade fatty acids and sterols, some of which act as natural antioxidants and accelerators, and some can help the powdered compounding agent disperse and soften the raw rubber during the mixing process.

The ash mainly contains salts such as magnesium phosphate and calcium phosphate, and there are very small amounts of metal compounds such as copper, manganese, iron, etc., because these valence metal ions can promote the aging of rubber, so their content should be controlled.

The moisture in the dry rubber does not exceed 1%, and it can be volatilized during processing, but when the moisture content is too much, it will not only make the raw rubber easy to mold during storage, but also affect the processing of rubber, such as the compounding agent is easy to agglomerate during mixing; It is easy to produce bubbles in the process of calendering and extrusion, and bubbles or sponges are produced in the process of vulcanization.

The main component of rubber is latex. Rubber tree will flow out of the latex, is a good raw material for rubber products, natural rubber is made of latex, and some of the non-rubber components contained in the latex remain in the solid natural rubber.

Rubber refers to a highly elastic polymer material with reversible deformation, which is elastic at room temperature, can produce large deformation under the action of small external force, and can return to its original state after removing external force. Rubber is a completely amorphous polymer with a low glass transition temperature (tg) and a often large molecular weight, greater than hundreds of thousands. Rubber is divided into two types: natural rubber and synthetic rubber.

Natural rubber is made from rubber trees, rubber grass and other plants after extracting gum; Synthetic rubber is obtained by polymerization of various monomers.

Application of rubberRubber can be used for transportation, tires and other major accessories, and can also be used for medical gas bags, anti-radiation aprons, gloves, ice packs, hot water bottles, etc., and is widely used in the military. It can be said that rubber is a necessary material for the manufacture of aircraft, automobiles, tractors, harvesters, water conservancy and irrigation machinery, medical equipment, etc., and is widely used.

Natural rubber is a natural polymer that comes from the sap of rubber trees, and its main component is rubber emulsion. This emulsion contains a variety of complex polymer organic compounds, the most important of which are natural rubber particles.

The structure of natural rubber.

Natural rubber particles are spherical or oval in shape, with molecular weights of hundreds of thousands or even millions. Its molecule consists of a large number of isoprene and acrylic units linked by covalent bonds, so its structure is very complex.

Preparation of natural rubber.

The preparation of natural rubber needs to be obtained by a series of processes such as mixing, concentration, dehydration, coagulation, cleaning and drying with the exudate of rubber tree as raw material. Because this process involves complex physicochemical changes, it is difficult to prepare.

Properties of natural rubber.

Natural rubber has excellent physical and mechanical properties, chemical stability, electrical insulation, waterproofness and other characteristics, and is a very important polymer material. Due to the complexity of its molecular structure, its properties are also very variable, and rubber with different properties can be obtained by controlling different production conditions.

Brief summary. In general, natural rubber is a polymer organic compound prepared from rubber emulsion in rubber tree exudate, and its molecular structure is very complex, which has a wide range of application prospects and development prospects.

1.The main chemical composition of rubber.

Rubber is an elastic material, which is mainly composed of polymer substances. Among them, the main chemical component is the polymer, and "polymerization" means that this is made up of many identical molecular units. This molecular unit is called "isoprene".

Rubber molecules are mainly made up of isoprene units attached.

2.How rubber is processed.

Rubber is usually made into blocks so that it can be used in the processing process. They can be calendered and cut into a variety of shapes. Rubber processing often requires some chemical treatment to make it easier to form the desired shape.

They often require a cross-linking process, which means that sulfides are added to form a cross-linked structure of the rubber, making it more durable. Vulcanization makes rubber stronger, more resistant to heat and chemicals.

3.Characteristics of rubber.

Rubber has a number of unique properties that make it an ideal material for many products. They have excellent elastic, tensile and tear resistance. In addition, rubber is resistant to heat, chemicals and abrasion.

These properties make rubber an ideal material for many products, such as tires, seals, pipes, solid rubber vibrators, and many more.

4.Uses of rubber.

Rubber is a basic material for a wide range of applications. It is widely used in products such as tires, seals, pipes, solid rubber vibrators, wires and cables, medical devices, artificial gloves, and other leather goods. In addition, rubber is also widely used in construction, automotive, aerospace, electronics, oil, gas and other industrial fields.

5.The production process of rubber.

In the production of rubber, the emulsion must first be collected. The method of collection is to make a small opening in the trunk of the rubber tree to allow the emulsion to flow out and collect it in an aggregate bucket. The emulsion is then processed with sulfur and other chemicals and stirred for several hours.

Next, the rubber is shaped and calendered, and finally vulcanized.

6.Sustainability of rubber.

The environmental impact of rubber production is significant, such as the need to cut down large quantities of rubber trees to obtain rubber emulsions, which can lead to large-scale land destruction and deforestation. In addition, the processing of rubber also produces waste water and exhaust gases, which cause pollution to the environment. To promote sustainable development, rubber producers should reduce their environmental impact by adopting sustainable measures, such as planting new natural rubber trees and developing waste**.

7.The future of rubber.

In the future, the application of rubber will be more extensive. For example, research is underway into the use of rubber in the manufacture of new materials such as solar cells and supercapacitors. In addition, with the development of various "smart" products, rubber will play an important role in new robots, smart homes, virtual reality and other products.

It is foreseeable that rubber will become a more diverse and innovative material in the future.
