Preparation method of stratified-structure mineral reinforced rubber composite material

Abstract

The invention relates to a preparation method of a stratified-structure mineral reinforced rubber composite material. The preparation method comprises the following steps: (1) carrying out nano-organic modification on a stratified-structure mineral; (2) preparing an organic modified nano-stratified-structure mineral inserted rubber master batch; (3) preparing the raw materials of an organic modified nano-stratified-structure mineral reinforced rubber composite material; and (4) preparing the organic modified nano-stratified-structure mineral reinforced rubber composite material, wherein the stratified-structure mineral is one or mixture of two of black talc, montmorillonite, kaolin and illite in the same mass ratio. According to the preparation method, the functional rubber composite material with excellent mechanical property, stable weather resistance and good warping strength and humidity resistance is prepared.

Description

Technical field [0001] The invention relates to a layered structure mineral reinforced rubber composite material, in particular to a preparation method of a layered structure mineral reinforced rubber composite material, and belongs to the field of material preparation. Background technique [0002] Rubber refers to a highly elastic polymer material with reversible deformation. It is elastic at room temperature and can produce greater deformation under a certain external force. It can be restored to its original state after the external force is removed. Because of its excellent elasticity, sealing and wear resistance, it is widely used in many fields such as tires, seals, and damping materials. In recent years, with the continuous development of the automobile industry, the requirements for various parts and components made of rubber as raw materials have continued to increase. Not only are they required to have good mechanical properties, but they also need to have excellent el...

Problems solved by technology

For this reason, many people have also carried out related research, and there are many related patents. For example, ZL.201510612132.4 introduces a preparation method of low-temperature-resistant environmental-friendly chlorinated polyethylene rubber, which has better physical and mechanical properties and low-temperature brittleness. temperature, and reduce the production cost, but the rubber additives used are complicated, and the colloid is powdery, which is not easy to process and easy to cause pollution; ZL.201310110342.4 uses a mixing process to prepare a high-strength, high-tear resistance and extra-heavy-duty sheath rubber. This kind of process is likely to cause uneven dispersion of fillers and form a "hard core". At the same time, the preparation process takes a long time and the process is complicated; ZL.201510082106.5 invented a new type of odorless molecular weight regulator to replace the mercaptan used in emulsion polymerization. Realize no peculiar smell in the production process; ZL.201310292284.1 loads the anti-aging agent on the inorganic carrier. This loaded anti-aging agent is not only efficient, but also environmentally friendly, but the anti-aging agent will inevitably occupy the inorganic material during the loading process. active sites, which may reduce the activity of inorganic fillers

There are also people who study the modification of rubber inorganic fillers, such as CN 105131442 A, which obtains modified ground calcium carbonate by means of ultrasonic and stirring; Chloroprene, found that the modification effect of mercaptosilane is the best; Liu Qinfu et al. intercalated kaolin with quaternary ammonium salt and γ-aminopropyltriethoxysilane respectively, and achieved good intercalation effect, but the number of times of methanol cleaning was too much. Reagent waste, serious pollution, and harmful to human body
