Problems solved by technology

However, it has poor stability to light and heat. When it is above 100°C or exposed to the sun for a long time, it will decompose to produce hydrogen chloride, and further autocatalyze the decomposition, causing discoloration and rapid decline in physical and mechanical properties. In practical applications, stabilizer must be added. agent to improve heat and light stability

Abstract

The invention discloses a PVC (Polyvinyl Chloride) flocking composite material and a preparation method thereof. The PVC flocking composite material is prepared from the following components in parts by mass: 70-90 parts of PVC, 20-30 parts of short fibers, 5-15 parts of triphenyl phosphate, 0.2-0.6 part of paraffin, 0.5-1.5 parts of stearate, 5-10 parts of chlorinated paraffin, 1-3 parts of dioctyl phthalate, 5-10 parts of polyvinyl ester, 1-3 parts of epoxy linseed oil, 3-8 parts of light calcium carbonate, 2-5 parts of an antistatic agent, 1-3 parts of an antioxidant, 0.1-1.0 part of a dispersant and 0.1-0.5 part of a de-foaming agent. The PVC flocking composite material has the characteristics of inflaming retarding, water prevention, no deformation, no fading and high strength, is produced by a machine and can be continuously molded; the PVC flocking composite material can be used as a novel high-grade indoor decorative material; after the PVC flocking composite material is used for decorating, the hand feeling is soft, the third dimension is strong and the sound absorption and heat preservation are realized.

Description

technical field [0001] The invention belongs to the technical field of composite materials, and in particular relates to a PVC flocking composite material and a preparation method thereof. Background technique [0002] PVC material is polyvinyl chloride, which is a material with a wide range of uses and is often used in our lives. Such as PVC pipe, PVC floor, PVC wallpaper and so on. PVC material is a thermoplastic resin polymerized by vinyl chloride under the action of an initiator. It is a homopolymer of vinyl chloride. Vinyl chloride homopolymers and vinyl chloride copolymers are collectively referred to as vinyl chloride resins. PVC is a white powder with an amorphous structure and a small degree of branching. The molecular weight of industrially produced PVC is generally in the range of 50,000 to 120,000, with a large polydispersity, and the molecular weight increases with the decrease of the polymerization temperature; there is no fixed melting point, it starts...
