Summary of the invention
In order to overcome above-mentioned defect, the invention provides the super fine preparation method of a kind of nanometer, the advantages such as that the super fine preparation method production technology of this nanometer product simple, that produce has is ventilative, soft, good hand feeling, good springiness.
The present invention for the technical scheme that solves its technical problem and adopt is: the super fine preparation method of a kind of nanometer, and concrete steps are as follows:
Step 1: mix:
A, 5-10kg dimethyl formamide, 2-10kg hydrolysis mill base and 1-3kg surfactant high-speed stirring is even, filters stand-by;
B, by 80-100kg high hydrolysis resistance polyurethane resin and 150-280kg dimethyl formamide mixing and stirring, after mixing with slurry in step a after standing 20-45 minute, under 20 ℃ of-40 ℃ of temperature conditions, stir, and deaeration filters staticly, froth breaking is stand-by;
Step 2: select the uniform fleece of fluffing;
Step 3: wet method bass is produced:
The fleece of choosing is fully contained and is immersed in the slurry preparing in step b after whole scalding, make to contain in flannelette high hydrolysis resistance polyurethane resin, then in the middle of putting into mass percent concentration and be the dimethyl formamide aqueous solution of 12-25%, solidify, then carry out multiple tracks washing, extruding post-drying obtains the super fine wet method bass of nanometer;
Step 4: post processing mill skin:
The super fine wet method bass of above-mentioned nanometer carries out surface finish in the situation that running up through sand paper, until its surperficial feel is fine and smooth, the feel of wool evenly; It is super fine that the super fine product of nanometer of the rear gained of polishing processes by net grain surface the nanometer that gets product again.
As a further improvement on the present invention, the mixture high-speed stirred 60-90 minute in described step a.
As a further improvement on the present invention, the high hydrolysis resistance polyurethane resin in described step b and dimethyl formamide mix high-speed stirred 30 minutes.
As a further improvement on the present invention, in described step b high hydrolysis resistance polyurethane resin and dimethyl formamide mixing and stirring after standing with step a in slurry mix and blend and deaeration in the reactor of negative pressure vacuum-pumping, mixing time is 2 hours.
As a further improvement on the present invention, in described step 3 wet method bass production stage, baking temperature is 100-160 ℃, and this operation speed of a motor vehicle is controlled at 6-15m/min.
As a further improvement on the present invention, in described step 4, the super fine wet method bass of nanometer of post processing mill skin operation adopts 100 order sand paper to polish.
As a further improvement on the present invention, in described step 4, the super fine product of nanometer after polishing is processed by 100 order net grain surfaces.
The invention has the beneficial effects as follows: the present invention mainly adopts high hydrolysis resistance polyurethane resin to prepare wet method bass, skin is ground through post processing in its surface, the super fibre of nanometer of its production has that surface is fine and smooth, the feel of wool evenly, there is the advantages such as certain puckery feel, ventilative, softness, good hand feeling, good springiness.
