Embodiment 1

[0028] Add 35g of water-soluble urea-formaldehyde resin and 15g of water into the mixing tank in turn, and stir while pouring in, and stir for 20min to mix evenly to obtain component A; add 50g of water-based stearic acid, 75g of water-based zinc stearate, water-based Add 75g of calcium stearate and 50g of water into the mixing tank in turn, and pour it in while stirring to make it evenly mixed to obtain component B; add 130g of talc powder, 10g of titanium dioxide, and 60g of water into the mixing tank in turn , pour while stirring while pouring, make it mix homogeneously, obtain C component; Then A, B, C component mix, stir, promptly obtain 500g solid content and be the super coating environmental protection coating of 47.3wt%.

Embodiment 2

[0030] First prepare aqueous lithium stearate: add 86kg deionized water in the reactor, add 1kg sodium tripolyphosphate, 1kg Tween 80 and 1kg Span 80 and 10kg lithium stearate under stirring at a stirring speed of 2000r / min, Then use a pipeline shearer to stir at a high speed of 8000r / min for 20 minutes to completely emulsify and disperse the materials in the reactor; Preservatives, mechanically stirred for 10 minutes; the resulting mixture was input into a horizontal sand mill and ground for 10 minutes until there were no obvious agglomerates, and then filtered through a 1000-mesh ultrasonic vibrating sieve to obtain a viscosity of 20mPa·S and an average particle size of 25μm , Aqueous lithium stearate with a solid content of 10 wt%.

[0031] Add 27.5g of water-based urea-formaldehyde resin of component A, 10g of water-based melamine-formaldehyde resin, and 12.5g of water into the mixing tank in turn, and stir while pouring to make it evenly mixed; 62.5g of water-based steari...

Embodiment 3

[0033] First prepare aqueous lithium stearate: add 85kg deionized water to the reactor, add 1kg sodium polyacrylate, 1.3kg fatty alcohol polyoxyethylene ether and 12kg lithium stearate under stirring at a stirring speed of 2000r / min, and reuse The pipeline shearer stirred at a high speed of 9000r / min for 40 minutes to completely emulsify and disperse the materials in the reactor; then add 0.1kg of emulsified silicone oil defoamer and 0.1kg of dichlorodimethylhydantoin Preservatives, mechanically stirred for 15 minutes; put the resulting mixture into a horizontal sand mill and grind it for 15 minutes until there is no obvious agglomerate, and then filtered through a 1000-mesh ultrasonic vibrating screen to obtain a viscosity of 30mPa.S and an average particle size of 35μm , Aqueous lithium stearate with a solid content of 12 wt%.

Abstract

The invention discloses a super environment-friendly coating for an abrasive paper, an abrasive cloth and an abrasive belt and a preparation method of the coating. The coating is prepared from a component I, a component II and a component III, wherein the mass ratio of the component I to the component II to the component III is 50:(200-300):(150-250); by weight percent, the component I comprises 70%-90% of an adhesive and 10%-30% of water, the component II comprises 70%-80% of a heat absorber and 20%-30% of water, and the component III comprises 65%-80% of fillers and 20%-35% of water; the heat absorber adopts one or a mixture of two or more of water-soluble stearic acid, water-based calcium stearate, water-based zinc stearate, water-based aluminum stearate and water-based lithium stearate. The preparation method comprises the following steps: preparing the component I, the component II and the component III respectively, and uniformly stirring according to the ratio. The coating is safe and environmentally friendly, and has an anti-blockage function; the preparation method is simple in flow process and easy to operate.

Description

technical field [0001] The invention belongs to the technical field of environmental protection coatings, in particular to a super-coating environmental protection coating for sandpaper, abrasive cloth and abrasive belts and a preparation method thereof. Background technique [0002] In the abrasives and abrasives industry, sandpaper, emery cloth, and abrasive belts are widely used as grinding tools. Different types of sandpaper, abrasive cloth, and abrasive belts have the advantages of wide range of use, convenient use, and low price. However, when using sandpaper, abrasive cloth, and abrasive belts to grind and polish soft materials such as paint, wood, soft metals, precision castings, and high-end furniture, ordinary sandpaper, abrasive cloth, and abrasive belts tend to be blocked by debris. , affecting the performance and service life of sandpaper, abrasive cloth, and abrasive belts. At present, the commonly used solvent-based super-coating coatings have high productio...
