Problems solved by technology
[0005] However, taking a comprehensive look at the above-mentioned conventional artificial leather production methods, it is very complicated and must consume more man-hours and equipment, which is not economically beneficial. Moreover, organic solvents are toxic, which not only has chronic harm to the human body, but also has a negative impact on the environment. Causes great pollution, so many countries have banned the use of related organic solvents

The invention provides breathable artificial leather and a manufacturing method thereof. The manufacturing method includes the following steps of heating, wherein polyurethane resin with the solid content weight percentage of 100% is heated to reduce the viscosity of the polyurethane resin so as to form a raw material, and the polyurethane resin is prepared from polyester polyol, polyether polyol and isocyanate; guiding-in, wherein the raw material in guided on a base material; coating, wherein the surface of the base material is uniformly coated with the raw material; rolling, wherein the coated base material and the raw material are rolled into bundles together to form a semi-finished product; ripening, wherein the semi-finished product stands so that polyurethane resin in the raw material and water molecules in air can be connected in a bridged mode to generate carbon dioxide, the raw material uniformly foams to form a foaming layer, and then the breathable artificial leather is obtained.
Description
technical field [0001] The present invention relates to a breathable artificial leather and its manufacturing method, which is formed by uniform foaming of polyurethane resin with a solid content of 100% and water molecules in the air, so that the artificial leather of the present invention has excellent breathability sex. Background technique [0002] With the development of industrial technology, the production technology of artificial leather is also improving day by day. It can be matched with different substrates and used in different processing methods to produce artificial leather with different characteristics and surface patterns. Therefore, compared with natural leather, Artificial leather has the advantages of multi-function and diversification. [0003] In the conventional artificial leather, polyurethane resin (Polyurethane, referred to as PU) with a solid content of about 50% to 60% by weight is the most common raw material composition, and in the manufacturin...
