Abstract
The invention discloses a cold resistant finishing agent for leather. The cold resistant finishing agent comprises 33-44% of toluene diisocyanate, 8-37% of trimethylolethane, 13-23% of potassium persulphate, 8-17% of perchlorethylene, 1-7% of dibasic lead stearate, 3-11% of polydimethylsiloxane and 1-6% of butylated hydroxyanisole. Compared with a prior art, the cold resistant finishing agent for leather provided by the invention not only has excellent low temperature flex resistance but also reaches highlight brightness, strong crystal feel and stereo perception on leather, so as to realize better visual effect.
Description
Technical field
The present invention relates to the leather finishing agent technical field, particularly a kind of cold resistant paint for leather.
Background technology
Artificial leather class synthetic leather has following several kinds:
Existing high light class synthetic leather product, though the glossiness of product is good, quartzy sense and third dimension are not strong, transparency is not high, product is high-grade inadequately; And low, the anti-tortuous poor performance of low temperature of high light class synthetic leather product elongation, overall performance is not high, can not satisfy people can enjoy high-quality emulational leather again in environmental protection demand.
Leather finishing agent is a kind of synthetic leather finish materials, is used for that durability is beautified and improved on the synthetic leather surface and handles, and can effectively improve the quality and the added value of synthetic leather.Though traditional moisture curing type coating agent can improve the glossiness of synthetic leather to a certain extent, does not reach comparatively desirable degree, and the anti-tortuous poor-performing of low temperature, overall performance is not high.
Summary of the invention
To the problems referred to above that exist in the prior art, the purpose of this invention is to provide a kind of cold resistant paint for leather, this finishing agent can make that the crystal sense of leather products is strong, transparency is high, third dimension is strong, the anti-tortuosity of low temperature is good, and then improves its product overall performance.
For realizing above-mentioned purpose; The technical scheme that the present invention adopted is: a kind of cold resistant paint for leather, said each component and weight percent content thereof are respectively: toluene di-isocyanate(TDI) 33-44%, trimethylolethane 8-37%, potassium peroxydisulfate 13-23%, perchloroethylene 8-17%, dibasic lead stearate 1-7%, dimethyl silicone polymer 3-11%, butylated hydroxy anisole 1-6%.
The preparation method of above-mentioned prescription and processing step are: toluene di-isocyanate(TDI) 33-44%, trimethylolethane 8-37%, potassium peroxydisulfate 13-23%, dibasic lead stearate 1-7%, dimethyl silicone polymer 3-11%, butylated hydroxy anisole 1-6% are dropped in the agitated reactor be heated to 80-100 ℃, stir about 8-11 hour to detecting reaction end; Perchloroethylene 8-17% is added into stirred again in the agitated reactor 1-1.5 hour; Being cooled to normal temperature gets final product.
Cold resistant paint for leather provided by the invention compared with prior art not only has the anti-tortuous performance of very good low temperature, and covering with paint can reach on leather, and high brightness is felt with strong crystal, third dimension, has better visual effect.
The specific embodiment
Come further to set forth cold resistant paint for leather of the present invention below in conjunction with instance.
Embodiment 1: a kind of cold resistant paint for leather of the present invention, and measure each composition weight respectively and be: toluene di-isocyanate(TDI) 35KG, trimethylolethane 22KG, potassium peroxydisulfate 15KG, perchloroethylene 10KG, dibasic lead stearate 5KG, dimethyl silicone polymer 9KG, butylated hydroxy anisole 4KG.
The preparation method of above-mentioned prescription and processing step are: toluene di-isocyanate(TDI) 35KG, trimethylolethane 22KG, potassium peroxydisulfate 15KG, dibasic lead stearate 5KG, dimethyl silicone polymer 9KG, butylated hydroxy anisole 4KG are dropped in the agitated reactor be heated to 88 ℃, stir about 11 hours is to detecting reaction end; Perchloroethylene 10KG is added into stirred again in the agitated reactor 1.5 hours; Being cooled to normal temperature gets final product for 25 ℃.
Embodiment 2: a kind of cold resistant paint for leather of the present invention, and measure each composition weight respectively and be: with toluene di-isocyanate(TDI) 41KG, trimethylolethane 18KG, potassium peroxydisulfate 20KG, perchloroethylene 11KG, dibasic lead stearate 3KG, dimethyl silicone polymer 5KG, butylated hydroxy anisole 2KG.
The preparation method of above-mentioned prescription and processing step are: toluene di-isocyanate(TDI) 41KG, trimethylolethane 18KG, potassium peroxydisulfate 20KG, dibasic lead stearate 3KG, dimethyl silicone polymer 5KG, butylated hydroxy anisole 2KG are dropped in the agitated reactor be heated to 95 ℃, stir about 10 hours is to detecting reaction end; Perchloroethylene 11KG is added into stirred again in the agitated reactor 1 hour; Being cooled to normal temperature gets final product for 25 ℃.
Like the prescription of above-mentioned embodiment, adopt other cold resistant paint for leather that obtained with the same or similar prescription of this embodiment, all within protection domain of the present invention.
