Reinforcing filler used for rubber latex product, preparation method thereof and application thereof

Abstract

The invention relates to reinforcing filler used for a rubber latex product, a preparation method thereof and application thereof. The reinforcing filler consists of the following components in part by weight: 50 to 80 parts of base material, 0.01 to 0.4 part of dispersant, 0.001 to 0.5 part of surface treating agent, 0.01 to 1 part of emulsion and 20 to 50 parts of water, wherein the base material is any one of heavy calcium carbonate powder, kaolin powder and argil powder; the dispersant is any one of casein, methylene dinaphthalene sodium sulfonate, sodium polyacrylate, potassium hydroxide and ammonia water; the surface treating agent is any one of bentonite, cellulose, swelling soil and attapulgite; and the emulsion is any one of mineral oil, vaseline, liquid paraffin and polyoxychloroethylene wax. The reinforcing filler has economic formulation and good reinforcing effect. The preparation method is a conventional stirring and grinding method. The process is simple, and little equipment is used. The application comprises the following steps: adding the reinforcing filler into rubber latex, blending the mixture evenly, forming a layer of film on a die by adopting a soaking and casting method, and then drying the film for 15 to 30 minutes at a temperature of between 110 and 130 DEG C to obtain the reinforced filled rubber latex product. The reinforcing filler is favorable for improving the tensile strength of the rubber latex product and reducing the usage amount of the latex.

Description

technical field [0001] The present invention relates to a reinforcing filler, more specifically, the present invention relates to a reinforcing filler for rubber latex products, meanwhile, the present invention also relates to a reinforcing filler for rubber latex products The preparation method and use of the agent. Background technique [0002] The latex industry is an important part of the rubber industry. Due to the rapid development of science and technology, the products of the latex industry have increasingly penetrated into various sectors of the national economy. Latex refers to a colloidal dispersion system with certain stability formed by polymer particles dispersed in water. Latex is divided into two categories, namely rubber latex and resin latex. [0003] Rubber latex products are widely used in various fields of industry, agriculture, national defense, medical care and people's life due to their certain ductility and flexibility. During use, rubber latex p...

Problems solved by technology

However, in the state of rubber latex, the addition of carbon black not only fails to achieve the reinforcing effect, but also often damages the physical properties of rubber latex. There are three main reasons for this: one is that carbon black is added to rubber latex in the form of water dispersion In the water dispersion, the carbon black in the water dispersion is mostly dispersed in the water phase in the form of various aggregates, which reduces the contact area between the carbon black and the rubber latex; the second is that when the rubber latex containing carbon black forms a film, the rubber latex particles The deposition rate of carbon black particles is different, which leads to the uneven distribution of carbon black in the rubber latex film; the third is the existence of protective substances on the surface of rubber latex particles, which hinders the direct contact between carbon black and rubber latex

[0007] As far as the applicant knows, there is currently no product in China that can effectively reinforce and fill rubber latex products
