Abstract

The invention discloses a preparation method for a waterproof coiled polyvinyl chloride material. The waterproof coiled polyvinyl chloride material is prepared through blending, granulation, cooling and shaping, and reeling successively. An environment-friendly plasticizer enhances the toughness of the coiled polyvinyl chloride material and allows the environment-friendly non-toxic coiled polyvinyl chloride material to be obtained; and the environment-friendly plasticizer used in a step A is one or more selected from a group consisting of tributyl citrate, dioctyl terephthalate, trioctyl trimellitate, the novel plant-based environment-friendly plasticizer ID37 and tri-n-butyl acetylacetate. According to the invention, through addition of an elastic material, the low temperature resistanceand the toughness of polyvinyl chloride are improved, the usage of the environment-friendly plasticizer is reduced, and the performance of the coiled polyvinyl chloride material is enhanced; a stirring speed is changed for different mixed materials to effectively keep the performance of the material, realize uniform mixing, control mixing temperature and reduce the performance loss of added materials.

Description

technical field [0001] The invention belongs to the technical field of waterproof coiled material, and in particular relates to a preparation method of polyvinyl chloride waterproof coiled material. Background technique [0002] With the development of the domestic economy and the rapid development of the construction industry, building waterproofing occupies a very important position in architectural design. Waterproofing engineering is an important subdivision of buildings. Layer waterproofing technology is to ensure that the building structure is free from water erosion, and the internal space A science and technology that is not damaged by water. The key to layer waterproofing lies in the quality of waterproof materials. At present, people's emphasis on the quality of building waterproof materials has changed from emphasizing economical cost to emphasizing environmental protection. [0003] The main types of new building waterproof membranes in my country are: asphalt m...
