Problems solved by technology

[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

Embodiment 1

[0019] An additive for artificial leather products and a preparation method, first weighing 1000kg of crushed branches, 100kg of hydrogen peroxide, 1kg of ultramarine blue, 80kg of glass water, 15kg of whitening agent, 10kg of caustic soda, and 25kg of sodium chloride nonahydrate; Put all the raw materials together in a mixing box and stir for 40 minutes to obtain a mixture, then dry the mixture and grind it into powder at 200°C with a mill to obtain a mixed powder. The mixture powder is sieved by a machine to remove impurities and unqualified components. The semi-finished product is then inspected and sterilized. After passing the test, it is packaged, and finally the finished product is inspected to obtain a qualified artificial leather additive.

Embodiment 2

[0021] An additive for artificial leather products and a preparation method, first weighing 1000 kg of crushed branches, 150 kg of hydrogen peroxide, 10 kg of ultramarine blue, 130 kg of glass water, 30 kg of whitening agent, 20 kg of caustic soda, and 50 kg of sodium chloride nonahydrate; Put all the raw materials together in a mixing box and stir for 40 minutes to obtain a mixture, then dry the mixture and grind it into powder at 200°C with a mill to obtain a mixed powder. The mixture powder is sieved by a machine to remove impurities and unqualified components. The semi-finished product is then inspected and sterilized. After passing the test, it is packaged, and finally the finished product is inspected to obtain a qualified artificial leather additive.

Embodiment 3

[0023] An additive for artificial leather products and a preparation method, first weighing 1000kg of crushed branches, 50kg of hydrogen peroxide, 0.5kg of ultramarine blue, 30kg of glass water, 5kg of whitening agent, 5kg of caustic soda, sodium chloride nonahydrate 1 by crushing branches and 5-15% hydrogen peroxide, 0.05-1% ultramarine, 3-13% glass water, 0.5-3% whitening agent, 0.5-2% caustic soda and 1-5% Composition of sodium sulfide nonahydrate. 0kg; then put the weighed raw materials together into a mixing box and stir for 40 minutes to obtain a mixture, then dry the mixture and grind it into powder at 200°C by a mill to obtain a mixed powder, and sieve the mixture powder through a machine Impurities and unqualified components are removed, and semi-finished products are inspected and sterilized. After passing the test, they are packaged, and finally the finished product is inspected to obtain qualified artificial leather additives.

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.
