A kind of additive for artificial leather products and its preparation method

Abstract

The invention relates to an artificial leather additive and a preparation method thereof. The invention relates to a field of artificial leather additive processing. According to the invention, the additive is composed of crushed tree branches, hydrogen peroxide accounting for 5-15% of the total weight of the crushed tree branches, ultramarine blue accounting for 0.05-1% of the total weight of the crushed tree branches, glass water accounting for 3-13% of the total weight of the crushed tree branches, a whitening agent accounting for 0.5-3% of the total weight of the crushed tree branches, caustic soda flake accounting for 0.5-2% of the total weight of the crushed tree branches, and sodium sulfide nonahydrate accounting for 1-5% of the total weight of the crushed tree branches. Through steps of stirring, sun-drying, pulverizing, powder sieving, quality inspection, sterilization, and bagging, finished products are obtained. According to the invention, the artificial leather additive is manufactured by using tree branches as a raw material, such that atmosphere pollution caused by a traditional preparation method using plastic is avoided, and resource is greatly saved. As it is known to all, wood is a renewable resource. With the circulated utilization method, harmful gas caused by plastic production is greatly reduced. Also, the cost of wood is low, and the additive production method is simple.

Description

Technical field: [0001] The invention relates to the field of artificial leather additive processing, in particular to an additive for artificial leather products and a production process thereof. Background technique: [0002] Artificial leather is also called imitation leather or rubber. It is a general term for artificial materials such as PVC and PU. It is made of foaming or coating of various formulations of PVC and PU. It has the characteristics of a wide variety of colors, good waterproof performance, neat edges, high utilization rate and relatively cheap price compared with real leather. However, when making artificial leather, in order to make it durable, And stylish and beautiful, it is necessary to add a kind of artificial leather additive, this additive is usually made of various plastics, this additive will have high manufacturing cost, the most important is because the plastic needs to be melted when making the additive , At this time, harmful gases will be pr...

[0002] Artificial leather is also called imitation leather or rubber. It is a general term for artificial materials such as PVC and PU. It is made of foaming or coating of various formulations of PVC and PU. It has the characteristics of a wide variety of colors, good waterproof performance, neat edges, high utilization rate and relatively cheap price compared with real leather. However, when making artificial leather, in order to make it durable, And stylish and beautiful, it is necessary to add a kind of artificial leather additive, this additive is usually made of various plastics, this additive will have high manufacturing cost, the most important is because the plastic needs to be melted when making the additive At this time, harmful gases will be produced, which will seriously pollute the environment. Therefore, the manufacture of a non-polluting, environmentally friendly and low-cost artificial leather additive is imminent
