Water-based carpentry putty

Abstract

The invention discloses water-based carpentry putty which comprises the following components by mass percent: 10-15% of water, 20-25% of zinc stearate emulsion, 20-25% of heavy calcium, 25-30% of light calcium, 5% of talcum powder, 2% of propylene glycol, 1% of a defoamer, 1-1.5% of a film former, a proper amount of a leveler and a proper amount of a thickener. The water-based carpentry putty is fine and smooth in surface, good in grindability and very good in heat resistance; the situation that a coating film is softened and adhered to abrasive paper or an abrasive wheel due to temperature rise during grinding of the abrasive paper or mechanical grinding of the abrasive wheel can be avoided; moreover, the water-based carpentry putty is good in transparence, difficult to precipitate and yellowing-resistant, can well protect wood after being applied, and prolongs the service life of carpentry.

Description

technical field

[0001] The water-based wood putty of the invention has strong corrosion resistance, smoothness and fineness, and good heat resistance. The invention belongs to the category of chemical coatings. Background technique

[0002] At present, wood coatings on the market have disadvantages such as non-environmental protection, peculiar smell, short shelf life, poor adhesion, poor sealing, and easy to fall off. The present invention is a water-based wood putty that replaces organic solvents with water, is environmentally friendly, has low VOC, and has strong adhesion. , Strong anti-aging power. Contents of the invention

specific Embodiment approach

[0005] detailed description The specific components, mass ratio of each component and specific production process of a water-based wood putty are as follows:

[0006] 1 Add 1% of preservative, 1% of defoamer, and 2% of propylene glycol.

[0007] 2 Add 25% heavy calcium, 30% light calcium and 5% talc.

[0008] 3 Grind the paint slurry after the dispersion is sufficient. The fineness of the grinding should be measured with a fineness meter and the fineness should be below 50um through the grinding machine to make the paint fineness reach the standard.

[0009] 4 Add 25% zinc stearate emulsion and stir well.

[0010] 5 Add proper amount of thickener, leveling agent, and film forming aid.

[0011] 6 After all the indicators are tested and qualified, it will be packed into barrels and wait for delivery.
