Abstract
The invention discloses a method for preparing synthetic leather of an electronic product. The method comprises the following steps of mixing and proportioning by a wet method; uniformly mixing dimethylformamide and wet type hydrolysis-resistant color slurry, and then uniformly mixing with the dimethylformamide and a surface active agent; adding a high hydrolysis-resistant polyurethane resin to uniformly mix, deaerating, filtering, standing, and defoaming for standby use; carrying out impregnating and permeating on the slurry, then causing flannel cloth to contain the high hydrolysis-resistant polyurethane resin, solidifying into films, and washing and removing the remained dimethylformamide from the leather by a multiple washing and extrusion process; drying and shaping; and finally grinding and napping a wet type Bass surface, inspecting and packaging. The synthetic fiber has the advantages that the water-proof and dirt-proof effects are realized, the touch feeling is soft, and a fine flannel feel is realized on the surface; the electronic product can be well protected; the flannel cloth is used as the wet type base cloth, so the synthetic leather has a double-side flannel feel property, and the electronic product can be well protected by any side of the synthetic leather; and the convenience in use is realized.
Description
Technical field
The present invention relates to a kind of artificial leather preparation method, particularly a kind of synthetic leather preparation method for electronic product.
Background technology
The displaying table top of the packing of electronic product and placement electronic product all needs soft packaging material, the packaging material quality of using at present is stiff, frictional force is little, and the phenomenon of skidding appears in electronic product easily on its surface, the situation on electronic product surface occurs scratching easily.
Summary of the invention
In order to overcome defects, the invention provides a kind of synthetic leather preparation method for electronic product, the synthetic leather preparation method technique that should be used for electronic product was simple, and the product of producing is soft, anti-skidding, can carry out well effectively protecting to electronic product.
The present invention for the technical scheme that solves its technical problem and adopt is: a kind of synthetic leather preparation method for electronic product, and concrete steps are as follows:
Step 1: wet-mixing batching:
With 20～40kg dimethyl formamide and 10～25kg wet method hydrolysis mill base high-speed stirred 15～20 minutes, then filter static stand-by; Then with said mixture, 60～180kg dimethyl formamide and 1～3kg surfactant mix and blend 15～20 minutes; Add 100kg high hydrolysis resistance polyurethane resin mix and blend 60～90 minutes under 20～40 ℃ temperature conditions, making the viscosity of above-mentioned mixing slurry is 500CPS-3000CPS again, and then deaeration, to filter static rear froth breaking stand-by;
Step 2: the wet method bass is produced:
Fleece is carried out whole boiling hot processing, then the method for the wet method slurry that forms in the step 1 being processed by the impregnation infiltration makes and contains the high hydrolysis resistance polyurethane resin in the flannelette, the high hydrolysis resistance polyurethane resin is by the displacement after coagulation film forming of organic solvent and water, clean residual dimethyl formamide in the leather through multiple tracks washing extrusion process again, then carry out drying and shaping, described bake out temperature is controlled at 100～160 ℃ (thickness of wet method bass layer can be controlled according to product requirement);
Step 3: surperficial napping is processed:
With the surface finish napping of above-mentioned wet method bass, to reach the velvet of the exquisiteness of positive and negative as superfine fibre;
Step 4: check, packing:
Gained finished product in the step 3 checked according to test stone and the packing case of packing in.
As a further improvement on the present invention, the mixture that dimethyl formamide and wet method hydrolysis mill base form in the described step 1 and dimethyl formamide and surfactant mix in the reactor that can take out negative pressure.
As a further improvement on the present invention, fleece is super fine fleece in described two.
The invention has the beneficial effects as follows: water proof anti-soil of the present invention; soft-touch; the surface has fine and smooth velvet; electronic product had splendid protective effect; more by adopting flannelette to do the wet method base cloth; so that synthetic leather has two-sided velvet characteristic, no matter use which face well to protect electronic product, easy to use.
The specific embodiment
Embodiment: a kind of synthetic leather preparation method for electronic product, concrete steps are as follows:
Step 1: wet-mixing batching:
With 20～40kg dimethyl formamide and 10～25kg wet method hydrolysis mill base high-speed stirred 15～20 minutes, then filter static stand-by; Then with said mixture, 60～180kg dimethyl formamide and 1～3kg surfactant mix and blend 15～20 minutes; Add 100kg high hydrolysis resistance polyurethane resin mix and blend 60～90 minutes under 20～40 ℃ temperature conditions, making the viscosity of above-mentioned mixing slurry is 500CPS-3000CPS again, and then deaeration, to filter static rear froth breaking stand-by;
Step 2: the wet method bass is produced:
Fleece is carried out whole boiling hot processing, then the method for the wet method slurry that forms in the step 1 being processed by the impregnation infiltration makes and contains the high hydrolysis resistance polyurethane resin in the flannelette, the high hydrolysis resistance polyurethane resin is by the displacement after coagulation film forming of organic solvent and water, clean residual dimethyl formamide in the leather through multiple tracks washing extrusion process again, then carry out drying and shaping, described bake out temperature is controlled at 100～160 ℃ (thickness of wet method bass layer can be controlled according to product requirement);
Step 3: surperficial napping is processed:
With the surface finish napping of above-mentioned wet method bass, to reach the velvet of the exquisiteness of positive and negative as superfine fibre;
Step 4: check, packing:
Gained finished product in the step 3 checked according to test stone and the packing case of packing in.
The mixture that dimethyl formamide and wet method hydrolysis mill base form in the described step 1 and dimethyl formamide and surfactant mix in the reactor that can take out negative pressure.
Fleece is super fine fleece in described two.
