Abstract

The invention discloses a polyvinyl chloride transparent weather-resistant sheet comprising the following components in part by weight: 100 parts of PVC resin, 3 to 4 parts of plasticizer, 1.5 to 2.5 parts of heat stabilizer, 0.2 to 0.3 part of external lubricant, 0.6 to 0.8 part of internal lubricant and 2 to 4 parts of weather-resistant modifier. The production process of the polyvinyl chloride transparent weather-resistant sheet comprises mixing, stirring, heating, cooling and unloading packaging of the components. The polyvinyl chloride transparent weather-resistant sheet disclosed by the invention has reasonable concept and standard technique, can be put into industrial mass production as soon as possible, and has the benefits of high strength, strong toughness, good weather resistance, no deformation because of heat resistance and no embrittlement because of cold resistance. The polyvinyl chloride transparent weather-resistant sheet can be widely applied in the fields of outdoor advertisements, decoration, automobiles curtain walls and the like.

Description

technical field [0001] The invention relates to a plastic sheet, in particular to a transparent weather-resistant polyvinyl chloride sheet. Background technique [0002] So far, the toughening modifier for rigid PVC (polyvinyl chloride) transparent sheet can only be methyl methacrylate, butadiene, styrene ternary graft copolymer (MBS). Due to the presence of double bonds in this modifier, the weather resistance of the prepared sheet product is very poor, and it can only be used indoors, which greatly limits the rigid PVC transparent sheet. Therefore, it is an urgent demand in the market to develop a transparent, weather-resistant, high-toughness rigid polyvinyl chloride transparent weather-resistant sheet. Contents of the invention [0003] The purpose of the present invention is to overcome the defects of the above-mentioned background technology and provide a transparent weather-resistant polyvinyl chloride sheet, which has high strength and good toughness, heat resista...
