Abstract

The invention discloses an adhesive for non-woven composite PVC decorative material processing. The adhesive comprises the following substances: corn starch, defatted soybean protein powder, sodium carbonate, urea, zinc chloride, a glyoxal solution, a functional enhancer, an emulsifying agent, an antioxidant and deionized water. Raw material components of the adhesive are optimized and improved, and the prepared adhesive is high in adhesive strength and good in affinity to non-woven fabric and a PVC material, can obviously improve the temperature resistance and the using stability of a non-woven composite PVC decorative material and prolong the service life thereof, and has very high market competitiveness and popularization and use values.

Description

technical field [0001] The invention belongs to the technical field of processing of decorative materials, and in particular relates to a binder for processing non-woven composite PVC decorative materials. Background technique [0002] Non-woven fabrics, also known as non-woven fabrics, are composed of directional or random fibers. They are a new generation of environmentally friendly materials. Low cost, recyclable and so on. PVC board is a board made of PVC with a honeycomb mesh structure in cross-section, also known as decorative film and adhesive film. It is used in many industries such as building materials, packaging, and medicine. It combines non-woven fabrics and PVC boards into Together, the decorative materials made not only have a beautiful appearance, but also have high wear resistance, heat resistance, and cold resistance. In the construction industry, this composite material can be used for architectural membranes, tents, sunshade curtains, building roof wate...
