Abstract

The invention discloses a production method for waterborne synthesized artificial leather and belongs to the technical field of leather fabric production. The production method sequentially comprises the following steps that pulp is prepared in a preparing chamber, wherein waterborne polyurethane pulp and polyvinyl chloride pulp are prepared; dry-method line coating bonding is carried out, wherein the surface of release paper is coated with the waterborne polyurethane pulp, the polyvinyl chloride pulp and waterborne polyurethane bonding pulp in sequence, and base cloth and a polyvinyl chloride layer are bonded to be prepared into a waterborne synthesized artificial leather body; the waterborne synthesized artificial leather body and the release paper are separated and rolled respectively, and coating is carried out with a printing machine, wherein coating wheels are used for uniformly coating the surface of the waterborne polyurethane layer of the waterborne synthesized artificial leather body with the waterborne polyurethane pulp, drying is carried out, and inspection and warehousing are carried out. The production technology is simple, the product is environmentally friendly, free of pollution and high in bonding property and composite strength, the service life is prolonged, the real leather imitation degree is high, the product is thick, solid and full, the comfortableness and softness of the artificial leather are improved, and the use demand is met.

Description

technical field

[0001] The invention belongs to the technical field of leather fabric production, and in particular relates to a production method of water-based synthetic artificial leather, which is mainly used in furniture fabrics such as sofas and seats. Background technique

[0002] Leather fabrics can be divided into genuine leather, regenerated leather, artificial leather and synthetic leather according to different manufacturing methods. Due to the scarcity of genuine leather resources and high prices, with the rapid improvement and improvement of leather production and processing technology, the production technology of artificial leather is becoming more and more mature. , the performance is getting better and better, artificial leather is used more and more in our daily life, and is widely used to make various leather products, or to replace part of the genuine leather material. The existing artificial leather technology has poor environmental protection. Harmful ...
