Abstract

The invention discloses a polyvinyl chloride profile. The polyvinyl chloride profile is prepared from, by weight, 80-120 parts of polyvinyl chloride, 10-30 parts of active calcium, 3-5 parts of a composite rare earth stabilizer, 5-15 parts of a processing agent, 4-7 parts of titanium dioxide, 0.1-0.5 part of calcium stearate, 0.1-0.5 part of PE wax and 0.001-0.002 part of ultramarine. Polyvinyl chloride is selected as a base material, auxiliary materials such as active calcium, the composite rare earth stabilizer and the suitable processing agent are combined, the prepared polyvinyl chloride profile is more excellent in tensile strength, impact strength, bending strength and the like, and the number of times of recycle is increased.

Description

technical field [0001] The invention relates to the technical field of plastic steel profiles, in particular to a polyvinyl chloride plastic steel profile and a preparation method thereof. Background technique [0002] Plastic steel profile, referred to as plastic steel, is a new type of building material that is widely used. This material has excellent performance, convenient processing, and a wide range of uses. , zinc, aluminum and other non-ferrous metals. It is mainly used in the application of push-pull, casement doors and windows, guardrails, pipes and ceiling materials in house construction. [0003] Plastic steel profiles are made of polymer resin as the main raw material, plus a certain proportion of stabilizers, colorants, fillers, ultraviolet absorbers, etc., and extruded into profiles. [0004] The reason why plastic-steel profiles can be widely applied and gradually replace wooden and aluminum doors and windows is inseparable from its unique advantages. Comp...
