Problems solved by technology

Traditional PVC leather surface treatment agents are all solvent-based, which are generally composed of resins, solvents and additives, of which solvents account for most of the weight, and the use of solvents causes solvent-based surface treatment agents to have the disadvantages of high price and large pollution , especially the solvent will bring environmental air pollution, and the gas produced by the volatilization of the solvent will cause great damage to the health of the operators. In view of this, it is urgent to develop low-pollution and non-polluting alternative products. Transformation is an effective development direction

Abstract

The invention discloses a water-based surface treatment agent for calendered PVC (polyvinyl chloride) leather, which is mainly prepared from water-based PU (polyurethane) resin, deionized water, a water-based leveling agent, a water-based defoamer and a water-based thickener by weight parts. Matting power and a water-based anti-adhesive can be also added to prepare the water-based surface treatment agent for the calendered PVC leather. The tests prove that the leveling property and the drying property of the water-based surface treatment agent for the calendered PVC leather can meet the requirement, is comparable with the traditional solvent product in surface treatment effect such as adhesive force, gloss and haze and is superior to the traditional solvent product in scratch resistance, hand touch sense fullness and texture finesses. The formula of the water-based surface treatment agent can be applied to the prior calendered PVC leather production line without changing the prior calendered PVC leather production equipment and increasing the calendered PVC leather product production cost. The water-based surface treatment agent for the calendered PVC leather is safe and environmental friendly, is easy to prepare, has low cost and can realize the industrial large-scale production easily.

Description

technical field [0001] The invention relates to a water-based surface treatment agent, in particular to a water-based surface treatment agent for calendered PVC leather. Background technique [0002] PVC (Polyvinylchloride) is the earliest artificial leather material invented in the world, and it is also one of the plastic products with the largest output. The main component of PVC is polyvinyl chloride. During the manufacturing process of its products, other ingredients can be added to enhance its heat resistance. Toughness, ductility, wear resistance, etc., with good processing performance, cheap price, corrosion resistance, etc., so it has been widely used in the world, common PVC material products such as PVC water pipes, PVC foam boards, PVC It is used to make imitation leather bags, sports goods and so on. [0003] Due to the use of a large amount of toughening agent in the manufacturing process of PVC leather, after high-temperature foaming, the plasticizer often app...
