Abstract

The invention relates to the technical field of leather preparation, in particular to water-proof leather and a preparation method thereof. The water-proof leather comprises a raw material 1, a raw material 2 and a water-proof agent; the raw material 1 comprises polyvinyl chloride, liquid polysulfide rubber, cottonseed oil, diallyl phthalate and cumyl hydroperoxide; the raw material 2 comprises polyvinyl chloride, liquid polysulfide rubber, cottonseed oil, diallyl phthalate, cumyl hydroperoxide and a foaming agent; the water-proof agent is mixed by modified wax oil, chlorcosane, hydroxy polysiloxane, camphorated oil and pentaerythritol; the water-proof leather not only keeps original mechanical strength, elasticity, heat-resisting stability and corrosion resistance performance but also hasexcellent water-proof performance.

Description

technical field [0001] The invention relates to the technical field of leather preparation, in particular to a waterproof leather and a preparation method thereof. Background technique [0002] Artificial leather is a composite material made of polyvinyl chloride or other resins mixed with certain additives, coated or pasted on the base material and then processed. It is similar to natural leather and has the characteristics of softness and wear resistance. . And polyvinyl chloride artificial leather (pvc artificial leather) is made by coating the paste made of PVC resin, plasticizer, stabilizer and other additives on the fabric or coating a layer of PVC film, and then processed through a certain process. . The product has high strength, easy processing and low cost. It can be used for all kinds of bags, seat covers, linings, sundries, etc. Artificial leather can be replaced in almost any occasion where leather is used, and is used to make a variety of daily necessities ...
