Abstract

The invention relates to the technical field of composite sheets, and in particular relates to a polyvinyl chloride-microfiber composite sheet and a laminating process thereof. The composite sheet comprises a PVC base material layer and microbfibers compounded on the surface of the PVC base material layer, wherein the PVC base material layer is prepared from the following raw materials in parts byweight: 80-120 parts of PVC resin, 55-65 parts of a filling agent, 20-30 parts of dioctyl phthalate, 2-3 parts of a heat stabilizer, 0.01-0.16 part of a toner material, 0.01-0.15 part of titanium dioxide and 0.15-0.7 part of other auxiliaries. The polyvinyl chloride-microfiber composite sheet provided by the invention has better toughness and air permeability, has extremely excellent wear-resisting property and excellent cold resistance, air permeability and ageing resistance and also has the advantages of good chemical stability, flame retardance and insulation, acid and alkali resistance, water and moisture resistance, corrosion prevention, tensile resistance and anti-static property, so that comprehensive performance is excellent.

Description

technical field [0001] The invention relates to the technical field of composite sheets, in particular to a polyvinyl chloride and superfiber composite sheet and a bonding process thereof. Background technique [0002] With the development of society, the improvement of human living standards and the constant pursuit of material, it is now more and more convenient, fashionable and beautiful to use in the field of household daily products. Soft polyvinyl chloride sheet is transparent and beautiful, soft in texture, and has been widely used in the field of daily products, such as tablecloths, table mats and place mats, some home decorations for floor mats, etc. This type of product is generally attached with a transparent film on the other side of the printed pattern. When it is covered on furniture, especially glass furniture, it can not only display the printed pattern on the transparent film, but also observe the shape of the furniture through the transparent film. Play a ...
