Abstract

The invention discloses a PVC (Polyvinyl Chloride) plastic particle formula, aiming at solving the problems of existing rigid PVC that the corrosion resistance is relatively low and the Vicat softening point and the tensile strength are relatively low. The PVC plastic particle formula is characterized by being prepared from the following components in parts by weight: 70 to 80 parts of PVC resin,2 to 3 parts of an organic tin stabilizing agent, 0.7 to 0.8 part of rigid calcium, 0.7 to 1.7 parts of a lubricant, 0.1 to 1 part of oxidized polyethylene wax, 0.7 to 1.7 parts of benzalkonium chloride, 2 to 3 part of an anti-impact modifying agent I, 0.5 to 1.5 parts of an anti-impact modifying agent II, 3.5 to 4.5 parts of mountain flour, 0.112 to 0.2306 part of color matching powder and 0.5 to1.5 parts of chlorinated polyethylene. According to the PVC plastic particle formula disclosed by the invention, PVC plastic particles have good corrosion resistance and relatively high Vicat softening point and tensile strength, so that the service life of pipe fittings and valves, which are prepared from the PVC plastic particles through injection molding, is prolonged.

Description

technical field [0001] The invention relates to a PVC plastic particle formula. Background technique [0002] PVC is a thermoplastic resin polymerized by vinyl chloride under the action of an initiator. PVC has good mechanical properties, the tensile strength is about 60mpa, the impact strength is 5-10kj / m2, and it has excellent dielectric properties. In practical applications, stabilizers need to be added to improve the stability to heat and light. In terms of specific applications, according to the main properties of PVC products, it can be divided into rigid PVC and soft PVC. Among them, rigid PVC is mainly used in pipe fittings, valves, profiles, etc., while soft PVC is mainly used in cables, hoses, electrical appliances, etc. etc. In the prior art, when rigid PVC is applied to pipe fittings and valves, due to poor corrosion resistance, Vicat softening point and low tensile yield force of rigid PVC, the service life of the pipe fittings and valves is relatively low. ...
