Embodiment 1

[0030] Embodiment 1: Stir 100 grams of raw material soapstone in 1000 grams of deionized water to form a stable suspension with a concentration of 10% mass fraction; prepare 0.141 moles of organic cationic salt cetyltrimethylammonium chloride in deionized water into a 2% mass fraction concentration solution. Stir the soapstone suspension at 90°C for 10 minutes at a stirring speed of 1000 rpm, then add the above-mentioned organic cation salt cetyltrimethylammonium chloride solution to the above-mentioned soapstone suspension, and react for 4 hours. Then filter. And the filtrate is washed several times with deionized water, and is detected by 0.1 mol / liter silver nitrate solution until there is no halogen ion in the washing liquid; the organic saponite after washing is dried and ground to obtain a particle size of 60 microns to 74 microns of organic saponite.

Abstract

This invention relates to a type of polychlorovinyl -organic soapstone composite material and the method. The feedstock includes polychlorovinyl resin, organic soapstone, modified resin, stabilizer, lubricant etc. The method includes steps as following: first mix the needed feedstock by high-speed warming mixer, then mix by low-speed cooling mixer, at last extrude out the polychlorovinyl -organic soapstone composite material directly from two-screw extruder machine. The feature is it elevates properties as extension at break, resistance to impact shock and tensile strength, and solves the problem of discoloration and degradation.

Description

technical field [0001] The invention relates to the technical field of polyvinyl chloride and organic saponite composite material, and relates to a polyvinyl chloride-organic saponite composite material, a preparation method and a product thereof. Background technique [0002] The use of inorganic materials to fill polymer resins to prepare composite materials is a technology that has been developed and applied for many years. The preparation of polymer composites with traditional inorganic fillers can reduce material costs and improve material properties, such as polyolefin plastics filled with calcium carbonate particles. Using nanometer-scale inorganic materials as additives to research and develop nanocomposites can significantly improve the performance of polymers, and its application development has attracted widespread attention. [0003] Polyvinyl chloride (PVC) is a bulk general-purpose resin, which has the advantages of flame retardancy, insulation, corrosion resi...
