[0022] Two. Preparation method of supercoating material for sandpaper

[0023] The supercoating material for sandpaper is prepared by mixing the above-mentioned components A, B and C, and the steps include:

[0024] (1) Preparation of component A: Pour 10-35% of the adhesive and 65-90% of the solvent into the reaction kettle in turn, and stir while pouring, and mix evenly.

[0025] (2) Preparation of component B: Pour 25-40% of endothermic agent, 20-30% of filler and 30-55% of solvent into the reaction kettle in sequence, and stir while pouring, and mix evenly.

[0026] (3) Mixing and preparation: first mix and prepare the prepared A and B components at a ratio of 100:200 to 350 by weight, stir evenly, then add component C to mix and prepare at 5 to 70 by weight, and stir evenly to obtain Supercoated material for sandpaper.

[0027] How to use the super-coating material: during normal use, it can be used by stirring evenly according to the ratio of component A: component B: ...

Embodiment 1

[0030] Example 1: Add 20% polyvinyl acetate-ethylene and 80% ethanol of component A to the reaction kettle in turn, pour in while stirring to make it mix evenly; add 30% calcium carbonate of component B , titanium dioxide 25%, ethanol 45%, add to the reaction kettle in turn, pour in while stirring to make it mix evenly; then mix A and B components according to the ratio of 100:250, stir evenly, Add toluene and adjust to proper viscosity to get the super coating material.

Embodiment 2

[0031] Example 2: Add 15% polyvinyl acetate-ethylene and 85% ethanol of component A to the reaction kettle in turn, pour in while stirring to make it mix evenly; add 35% calcium carbonate of component B , titanium dioxide 25%, ethanol 40%, add to the reaction kettle in turn, pour in while stirring to make it mix evenly; then mix A and B components according to the ratio of 100:250, stir evenly, Add toluene and adjust to proper viscosity to get the super coating material.

Abstract

A super coating material for adhesive paper is prepared from components A, B and C through preparing component A from adhesive and solvent, preparing component B from heat absorbent, filler and solvent, preparing component C from solvent, proportionally mixing A with B, stirring, proportionally adding C and stirring. Its advantages are low drying temp and high heat dissipating effect.

Description

technical field [0001] The invention relates to the field of materials, in particular to a supercoating material for sandpaper and a preparation method thereof. Background technique [0002] In the abrasives industry, sandpaper is a widely used grinding tool. Different types of sandpaper have the advantages of wide range of use, convenience, and low price. However, when sanding soft materials such as wood, paint, and soft metals, ordinary sandpaper tends to become clogged with debris. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a super-coating material for sandpaper and a preparation method thereof. The supercoat material has an anti-clogging function, thereby being able to overcome the above-mentioned deficiencies in the prior art. [0004] The technical solution adopted by the present invention to solve the technical problem is: the supercoating material for sandpaper is prepared by mixing components A, ...
