5.0 parts, 35-42 parts of acetone, 1-2 parts of H-66 surfactant, 70-80 parts of deionized water, 10-15 parts of attapulgite.
The attapulgite passes through modification, the specific steps are as follows:
(1) surface activation process:
Attapulgite is put into the hydrochloric acid solution that the mass fraction of 5 times of its weight is 15%, is filtered out after immersion treatment 15min；
(2) surface modification treatment:
By step (1) treated attapulgite high-temperature process 30min at 565 DEG C, it is then naturally cooling to room temperature, it will be concave-convex
Stick soil uses the sodium hydroxide solution elder generation immersion treatment 15min of mass fraction 10%, uses at ultrasonic oscillation in soaking process
Reason, then heated solution to temperature is 65 ~ 70 DEG C, filters after continuing immersion treatment 30-40min, it is spare to obtain filter residue；
(3) it is dried:
Step (2) resulting filter residue is put into drying box and is dried, keeping the temperature in drying box is 85 DEG C, place
It is taken out after managing 1.5h.
A kind of preparation method of adhesive used for artificial leather, comprising the following steps:
(1) polyvinyl acetate is added into the flask that thermometer, constant pressure funnel, electric mixer, reflux condensing tube are housed, gathers
Dimethyl siloxane, triethanolamine and acetone, stirring are warming up to 65-70 DEG C, and mixing speed is 320-330 revs/min, complete to it
After portion's dissolution, it is cooled to 45-55 DEG C, H-66 surfactant and sodium sulphate is added, is continued stirring and emulsifying 30-40 minutes；
(2) hydroxyethylmethylcellulose, magnesium chloride are mixed, is added in beaker, poured into deionized water mixing, dissolved
Waterglass is added after complete, is placed in high-speed mixer and mixes 10-15 minutes, be then heated to 45-55 DEG C, at this temperature aging
18-20 hours, continues that γ-aminopropyl triethoxysilane is added dropwise under stiring, be warming up to 60-65 DEG C, it is small to be stirred to react 2-3
When；
(3) reaction solution that step (2) is prepared is added dropwise in the emulsifying mixt of step (1), the drop in 1.5-2.0 hours
It adds, half potassium peroxydisulfate is added when being added dropwise to half, then stirring is warming up to 60-70 DEG C, and remaining potassium peroxydisulfate is added
Initiator insulated and stirred 30-40 minutes, is cooled to 40-45 DEG C, using phosphate buffer adjust pH value be 6.5-6.8, then plus
Enter attapulgite, discharges after cooling.
Step (3) the phosphate buffer pH value is between 7.3-7.5.
The present invention has the advantage that adhesive used for artificial leather of the invention compared with prior art, with the poly-vinegar of environment-friendly type
Vinyl acetate solves its water resistance, cold resistance, heat resistance, corrosion resistance and mechanical stability etc. all very as main body, by modified
The problem of difference, the adhesive adhesion strength being prepared is good, and caking property is original 5 times or more, utilizes waterglass and ethoxy
Methylcellulose is compound, carries out the modifying agent that silanization treatment is prepared and combines the advantages of inorganic material and polymer
Come, play synergistic effect, the good dispersion in lotion, so that gluing agent emulsion viscosity and hydrophobicity significantly improve, ensure that every
One condensation group has modified molecules package, and doping is few but to be influenced significantly, to improve the mechanics such as its cohesive force and adhesion strength
The problems such as performance, while its durability and toughness are also improved, the later period is not in contraction, cracking.
