Example Embodiment

[0026] Example 1: It is a 50 mold PU dry process resin 22%, a quarter second nitrocellulose 1%, ultrafine silica 9%, micronized polyethylene wax 1.2%, oily organic fluorine water and oil repellent 4%, castor Sesame oil 4%, organic silicon leveling and dispersing agent 0.5%, the balance butanone. The formula product of this example is suitable for the artificial leather burnt treatment of luggage leather.

[0027] The preparation method of the artificial skin burnt treatment agent for synthetic leather of the present invention includes the following steps: first add quarter-second nitrocellulose to methyl ethyl ketone in a dispersing machine or a dispersing reaction kettle to completely dissolve it Add superfine silicon dioxide, micronized polyethylene wax and organic silicon dispersion and leveling agent to disperse at high speed for 10 minutes, then add castor oil, 50 mold PU dry resin, and organic fluorine water and oil repellent to disperse evenly.

Example Embodiment

[0028] Example 2: 50 mold PU dry resin 20%, quarter second nitrocellulose 2%, superfine silica 10%, micronized polyethylene wax 1.5%, oily organic fluorine water and oil repellent 4%, castor Sesame oil 5%, organic silicon leveling and dispersing agent 0.5%, the balance butanone. The formula product of this example is suitable for the artificial light and bright burnt treatment of luggage leather and shoe leather.

Example Embodiment

[0029] Example 3: It is a 50 mold PU dry process resin 15%, a quarter second nitrocellulose 4%, ultra-fine silica 8%, micronized polyethylene wax 1.8%, oily organic fluorine water and oil repellent 4%, castor Sesame oil 3%, organic silicon leveling and dispersing agent 0.5%, the balance butanone. The formula product of this example is suitable for high-bright scorching treatment of artificial leather of luggage leather and shoe leather.

Abstract

The invention relates to crystal slippery resin for synthetic leather and a preparation method of the crystal slippery resin. The crystal slippery resin is formed by preparing the following raw materials in part by weight: 35 to 50 parts of dimethyl formamide, 8 to 15 parts of polyether polyol, 4 to 8 parts of polyester polyol, 10 to 30 parts of diphenylmethane diisocyanate, 0.5 to 1.8 parts of 1,4-butanediol, 3 to 6 parts of ethanediol, 10 to 20 parts of toluene, 10 to 20 parts of acetic ether, 3 to 5 parts of silicone emulsion and 0.01 to 0.03 part of antioxidant. The preparation method comprises the following steps of: performing addition polymerization reaction of the polyether polyol, the polyester polyol and diisocyanate to form a prepolymer; performing chain extension reaction to form polymer with high relative molecular mass; and performing chain extension reaction of diol and polyol on the prepolymer to prepare the resin. The invention has the advantage that the problems of pastiness of gloss oil resin and poor temperature resistance can be solved, the crystal slippery resin is high-temperature-resistant, folding-resistant, anti-aging, simple in process, convenient to produce and low in cost and can be directly applied to the subsequent production process, and the process can employ three-plate printing or spraying.

Description

technical field [0001] The invention belongs to a burnishing and polishing treatment agent for synthetic leather and a preparation method thereof, in particular to an imitation leather burnishing treatment agent for synthetic leather and a preparation method thereof. Background technique [0002] At present, with the improvement of people's living standards, there is more and more demand for genuine leather, but due to the rarity and preciousness of natural resources of genuine leather, the products of the synthetic leather industry must move closer to and develop towards genuine leather. Tactile agents, physical and mechanical strength and chemical resistance, so the development of leather surface imitation leather treatment is the main research direction of leather chemical companies. The coke polishing treatment agent is one of the best treatment agents for imitation leather. [0003] At present, the coke throwing treatment agent in the domestic market is basically produ...
