Energy-saving rigid plastic and preparation method thereof

Abstract

The invention discloses an energy-saving rigid plastic, which is composed of the following raw materials in parts by weight: 0.1-0.3 part of cadmium stearate, 6-10 parts of polyvinyl butyral, 130-170 parts of polyvinyl chloride, 1-2 parts of ammonium alcohol ether sulphate, 2-3 parts of an amino tri methylene phosphonic acid, 3-5 parts of zinc dihydrogen phosphate, 20-30 parts of rigid packing, 0.5-1 part of polyethyleneimine, 10-18 parts of epoxidized linseed oil, 3-4 parts of phytosterol, 0.6-1 part of tert-Butyldiphenylsilane, and 1-2 parts of methyl parahydroxybenzoats. According to the invention, octadecyl trimethyl ammonium chloride and potassium iodide are mixed for preparing hyamine iodide, and then the prepared hyamine iodide and dispersion liquid of aluminium-magnesium silicate are mixed for processing milltailings, in such a way, the water resistance and stability of the packing can be improved; and a rare-earth salt is also added, so that the resistance of the packing is improved. The plastic disclosed by the invention is rigid in surface texture, high in impact strength, and good in weather resistance, therefore, the energy-saving rigid plastic is particularly applicable to construction projects.

Description

technical field [0001] The invention relates to a plastic, in particular to an energy-saving hard plastic and a preparation method thereof. Background technique [0002] Polyvinyl chloride is a polymer formed by polymerization of vinyl chloride monomer in peroxide, azo compound and other initiators; or under the action of light and heat according to the mechanism of free radical polymerization. Vinyl chloride homopolymers and vinyl chloride copolymers are collectively referred to as vinyl chloride resins. Its material is an amorphous material. PVC materials are often added with stabilizers, lubricants, auxiliary processing agents, colorants, impact agents and other additives in actual use. It has non-flammability, high strength, resistance to climate change and excellent geometric stability. PVC has strong resistance to oxidizing agents, reducing agents and strong acids. However, it can be corroded by concentrated oxidizing acids such as concentrated sulfuric acid and co...
