Problems solved by technology

[0004] Existing PVC plastic special-shaped plates have the following defects: 1. High cost; 2. Poor thermal stability, hardening and brittle at low temperature, easy to soften and relax at high temperature; 3. Poor processing performance, impact resistance and aging resistance ; 3. Release harmful substances during the production process and produce hazardous waste products. The finished product will release dioxin acid gas at high temperature, and its additives will gradually volatilize during use, polluting the air

Abstract

The invention discloses a PVC board and a preparation process thereof. The PVC board is prepared from, by weight, 40-60 parts of polyvinyl chloride resin, 0.1-0.5 part of white oil, 2.5-3 parts of stabilizer, 1-3 parts of titanium dioxide, 0.1-0.5 part of stearic acid, 0.1-0.3 part of polyethylene wax, 0.01-0.5 part of octadecanamide, 0.01-0.2 part of ultraviolet absorbent, 0.01-0.03 part of colorant, 0.01-0.1 part of fluorescent whitening agent OB, 10-20 parts of activated calcium carbonate, 10-20 parts of talcum powder and 0.1-0.3 part of foaming agent. The PVC board is low in cost and good in heat stability, the rigidity is improved, the plastifying quality is improved, and the appearance is improved, so that section bars are smooth and good in weather resistance, toughness and uniformity.

Description

technical field [0001] The invention relates to the technical field of plate forming, in particular to a PVC plate and a preparation process thereof. Background technique [0002] Polyvinyl chloride, referred to as PVC in English, is a thermoplastic resin polymerized by polyethylene under the action of an initiator. The molecular weight of industrially produced PVC is generally in the range of 50,000 to 120,000. It has large dispersibility. The molecular weight increases with the decrease of polymerization temperature, but its stability to light and heat is poor. , it will be decomposed to produce hydrogen chloride, and further autocatalytic decomposition will cause discoloration, and the physical and mechanical properties will also decline rapidly. In practical applications, additives must be added to improve various performances. [0003] PVC plastic sheet is already a very popular new type of light-weight decorative material in the world today, and it is a popular produc...
