Polyvinyl chloride plastic with toughening effect

Abstract

The invention discloses a polyvinyl chloride plastic with a toughening effect, which comprises the following components in parts by weight: 100 parts of polyvinyl chloride, 6 to 9 parts of MBS (methyl methacrylate) resin, 8 to 12 parts of basic magnesium sulfate whisker, 2 to 4 parts of tribasic lead sulfate, 3 to 5 parts of dibasic lead phosphite, and 0.5 to 1 part of talcum powder. In the mode, the polyvinyl chloride plastic with the toughening effect, which is disclosed by the invention, is prevented from showing brittle when used for a long time in a room-temperature or low-temperature environment, so that the plastic always has a use value, the service life of the plastic can be prolonged, the plastic does not need to be replaced continuously, and accordingly, the cost is lowered.

Description

technical field

[0001] The invention relates to the field of modified plastics, in particular to a polyvinyl chloride plastic with a toughening effect. Background technique

[0002] Polyvinyl chloride plastic is polymerized from vinyl chloride monomer and is one of the most commonly used thermoplastics. Pure polyvinyl chloride resin is a hard thermoplastic substance, its decomposition temperature is very close to the plasticizing temperature, and its mechanical strength is poor. Therefore, polyvinyl chloride resin cannot be used to mold products, and plasticizers, stabilizers, fillers, etc. must be added to improve performance to make polyvinyl chloride plastics, and then processed into various products. Existing polyvinyl chloride plastics are not tough enough, tend to be brittle, and will break if they are not used for a long time. Contents of the invention

[0003] The main technical problem to be solved by the invention is to provide a polyvinyl chloride plastic with...
