Embodiment approach

[0031] As an embodiment of the present invention, the mixed fiber is formed by blending sepiolite fiber and glass fiber; because sepiolite fiber has good wear resistance, and glass fiber has higher strength, but there is For the problem of poor friction resistance, blending the two fibers can obtain a blended fiber with high strength and high wear resistance. When the water-based additive is applied to synthetic leather, it can not only improve the tear resistance of synthetic leather , At the same time, it can improve the wear resistance of synthetic leather.

[0032] As an embodiment of the present invention, the phospholipid molecular solution is formed by mixing and stirring phospholipid powder with water, wherein the specific preparation method of the phospholipid powder is: adding water to crude soybean oil, fully stirring at 70-90° C. for 30 min, The phospholipids are hydrated into colloidal precipitates, and the hydrated phospholipids are obtained by continuous centrif...

Abstract

The invention belongs to the technical field of water-based auxiliary agents for synthetic leather, and particularly relates to a water-based auxiliary agent for synthetic leather and a preparation method thereof. The water-based auxiliary agent comprises, 10-15 parts of polyvinylpyrrolidone, 5-7 parts of polyvinyl alcohol resin, 4-6 parts of phospholipid molecule solution, 2-3 parts of far infrared ceramic powder, 5-10 parts of polytetrafluoroethylene emulsion, 1-2 parts of polyethylene oxide, 2-3 parts of poly-1-butene, 1-2 parts of mixed fiber and 60-100 parts of water. The water-based auxiliary agent has the advantages that by adding polyvinylpyrrolidone and polyvinyl alcohol resin, good bonding performance and film forming performance are realized, so that polyurethane molecules can be better dispersed; in addition, the polyurethane molecules form stable colloid, so that the inside fluid of the synthetic leather is uniform, and the intensity is high; the poly-1-butene is added, the distinctive advantages of very excellent creep resistance, environmental stress crack resistance and impact resistance are realized; the far infrared ceramic powder is added, the ultraviolet ray shielding rate reaches up to 98%, and the effects of resisting and inhibiting bacteria, removing odor and preventing mildew are achieved; and the mixed fiber is added, the tearing-resistant performance of the synthetic leather can be improved.

Description

technical field [0001] The invention belongs to the technical field of water-based additives for synthetic leather, in particular to a water-based additive for synthetic leather and a preparation method thereof. Background technique [0002] Synthetic leather is a plastic product that simulates the composition and structure of natural leather and can be used as its substitute material. Usually, the impregnated non-woven fabric is used as the mesh layer, and the microporous polyurethane layer is used as the grain layer. Its front and back are very similar to leather, and has a certain degree of air permeability, which is closer to natural leather than ordinary artificial leather. It is widely used in making shoes, boots, bags and ball games. With the continuous development of technology and the continuous improvement of human living standards, the requirements for consumer goods are also getting higher and higher. However, due to the constraints of natural conditions and the...
