Problems solved by technology

However, in order to reduce the mobility of plasticizers, the types of ions must be designed according to actual needs, resulting in high production costs, complicated operations, and limited application fields.
[0006] In order to avoid the precipitation of small molecular plasticizers, polymer plasticizers have been widely used as polyvinyl chloride plasticizers, but polyester polymer plasticizers have large molecular weight, high viscosity, and low plasticizing efficiency. Better plasticizing effect requires a large amount of addition, which not only increases the cost but also increases the difficulty of processing

Abstract

The invention discloses a low precipitated polyvinyl chloride film structural material for plasticizer. The low precipitated polyvinyl chloride film structural material for the plasticizer is composed of the raw materials of, by weight, 100 parts of polyvinyl chloride resin, 30 to 60 parts of phthalic acid diisononyl phthalate, 5 to 35 parts of adipic acid polyester, 10 to 40 parts of active nano-calcium carbonate and 4 to 8 parts of other promoters. The invention also discloses a preparation method of the low precipitated polyvinyl chloride film structural material for the plasticizer. The low precipitated polyvinyl chloride film structural material for the plasticizer is acquired through a composite plasticizing system composed of the phthalic acid diisononyl phthalate and the adipic acid polyester combining with the special preparation method under the function of the active nano-calcium carbonate, and terrific stability and a terrific mechanical property are achieved.

Description

technical field [0001] The invention relates to the field of preparation of PVC materials, in particular to a polyvinyl chloride film structure material with low plasticizer precipitation and a preparation method thereof. Background technique [0002] At present, the polyvinyl chloride (PVC) membrane structure material is a composite material with polyester fiber fabric as the base and evenly coated with PVC membrane on the surface. Due to its excellent comprehensive performance, it is widely used in construction, sports, leisure and other fields. . In order to improve the processing and use performance of polyvinyl chloride materials, plasticizers are indispensable raw materials in the processing of polyvinyl chloride to improve the sliding between polyvinyl chloride chain molecules and achieve the purpose of plasticizing and softening. Especially for soft polyvinyl chloride film materials, 50-80% of small-molecule plasticizers need to be added during processing. However,...
