Embodiment 6
[0027] A kind of preparation method of the water-based neoprene that does not slag by roll coating, its component and the steps that comprise are as follows: Weigh 140g of neoprene latex C84, slowly add 0.6g mass concentration wherein to be 5% pH adjuster HBO 3 Aqueous solution and 0.3g mass concentration of 10% anti-slagging agent potassium pentaborate aqueous solution, after stirring fully, add 48g of styrene-acrylic emulsion under shear at 600rpm, disperse for 20 minutes, and finally add 10.89g of terpene phenol resin under stirring at 400rpm Aqueous dispersion and 0.21g hydroxymethyl cellulose, stir evenly to obtain slag-free water-based neoprene by roll coating.
Embodiment 7
[0029] A kind of preparation method of the water-based neoprene that does not slag by roll coating, its component and the steps that comprise are as follows: Weigh 140g of neoprene latex C84, slowly add 0.6g mass concentration wherein to be 5% pH adjuster HBO 3 Aqueous solution and 0.3g mass concentration of 10% anti-slagging agent lithium borate aqueous solution, after stirring fully, add styrene-acrylic emulsion 48g under shear at 900rpm, disperse for 25 minutes, finally add 10.89g terpene phenol resin water dispersion under stirring at 500rpm Body and 0.21g hydroxymethyl cellulose, stir evenly to obtain water-based neoprene without slag by rolling.
Embodiment 8
[0031] A method for preparing water-based neoprene by roller coating without slag, its components and steps are as follows: Weigh 140 g of domestic neoprene latex SNL-6042, and slowly add 0.6 g of a pH regulator with a mass concentration of 5% HBO 3 Aqueous solution and 0.3g mass concentration of 10% anti-slagging agent potassium pentaborate aqueous solution, after stirring fully, add 48g of styrene-acrylic emulsion under shearing at 800rpm, disperse for 25 minutes, finally add 10.89g of terpene phenol resin water under stirring at 450rpm Dispersion and 0.21g hydroxymethyl cellulose, stir evenly to obtain slag-free water-based neoprene by roller coating.
