A method for producing tsr9710 rubber with standard rubber as raw material

Abstract

The invention provides a method for producing TSR9710 rubber by using standard rubber as a raw material. The method comprises the following steps: cutting the standard rubber into bulks by using a technological formula; performing dry-mix crushing and float-washing; subsequently performing double-roller mixing, five-stage pressing and one-stage granulation to solve the problem of removal of impurities, dust and non-rubber foreign substances of rubber so that soft and hard parts of the rubber material are uniformly mixed and are convenient to dry; afterwards adding a parting agent and performing viscosity adjustment and oxidation resistance treatment on rubber particles; subsequently drying; afterwards performing rubber weighing, pressing, sampling, inspection and appearance inspection to pick out foreign substances; detecting by using a metal detecting instrument, packaging into boxes and then putting into storage. The method provided by the invention can effectively improve the consistency and stability of natural rubber, improves the quality of the rubber and realizes cost reduction and efficiency improvement.

Description

technical field [0001] The invention belongs to the field of rubber processing, and in particular relates to a method for producing TSR9710 rubber by using standard rubber as a raw material. Background technique [0002] Natural rubber is a natural polymer compound with polyisoprene as the main component. Its molecular formula is (C5H8)n, and 91-94% of its components are rubber hydrocarbons (polyisoprene), and the rest are proteins and fatty acids. , ash, sugar and other non-gum substances. Natural rubber is the most widely used general-purpose rubber. It has excellent comprehensive properties, such as high elasticity, high strength, high elongation, wear resistance, tear resistance, impact resistance, oil resistance, acid and alkali resistance, corrosion resistance, and Good insulation, sealing and adhesion. Due to its outstanding comprehensive properties, natural rubber is widely used in various fields such as industry, agriculture, national defense, transportation, and ...

Problems solved by technology

Due to the deteriorating quality of raw materials, it is inevitable that during the processing process, it is unavoidable to judge that the appearance quality is unqualified and downgraded to semi-finished products due to reasons such as raw spots, white glue, poor color, and foreign matter pollution. Therefore, the qualified rate of processed products is low, the efficiency is low, and the production cost is high.

[0004] In the case that the production process and equipment have not been improved, the traditional production and processing processes such as mixing, coagulation, crepe, granulation, and drying cannot be guaranteed to completely remove the non-adhesive foreign matter (such as bark, braid, etc.) attached to the raw material. bags, plastic cups, etc.), especially the problem of moth nests cannot be effectively solved

It puts a lot of pressure on the quality control of the production process, which will also have a greater impact on product quality, increase the difficulty of processing, and cause the quality of the produced products to be affected by raw material structure, raw material quality, weather changes, and production process defects. and other factors

At the same time, the inner packaging adopts the ordinary inner bag packaging method with high melting point, and only six indicators are tested according to the national standard in the finished product sampling and testing method, and the physical properties of the finished product are seldom tested, which has a negative impact on the tire customer's craftsmanship and product quality. There are also hidden dangers of customer quality complaints, and it is difficult to meet the testing needs of the top ten tire manufacturers in the world
