Problems solved by technology

Most of them are solvent-based fillers. Solvent-type fillers have excellent operability in large areas, but they contain aromatic hydrocarbons, alcohol ethers, and ether ester solvents, which are harmful to the health of operators and are likely to cause safety hazards such as fire.
[0003] Water-based fillers, such as water ash, which are commonly used in the wood coating market today, can only be applied by scraping. If the simple method of wiping is used, the operability of a large area is not good, which affects labor productivity.

Embodiment 1

[0031] Components and parts by weight:

[0032] 12 parts of water-based resin, 28 parts of deionized water, 10 parts of 200 mesh quartz powder, 50 parts of 425 mesh mica powder, 5 parts of iron red paste

[0033] Put the water-based resin in first, add 80% of the total amount of deionized water, add quartz powder and mica powder under medium speed stirring, after the dispersion is uniform, then add iron red slurry, and finally add the remaining 20% ​​of deionized water .

[0034] Wipe this product on ash or oak, sapele and other wood-grained boards, wipe it clean, after drying, then lightly sand the surface, spray the PU head bottom once, polish it after drying, spray PE primer once, and polish it after drying , Spray PU topcoat. The product can achieve a fully sealed effect. After drying for 48 hours, the adhesion is tested by the 100-grid method, and the adhesion is grade 1.

[0035] Spray the PU primer on the board wiped with filler, and polish it flat after drying, then...

Abstract

The invention provides an aqueous filler for woodware, which comprises the following components in portion by weight: 8 to 15 portions of water borne resin, 20 to 30 portions of water, 10 to 20 portions of filler A, 40 to 50 portions of filler B and 0 to 15 portions of pigment. The water borne resin is water-reducible alkyd resin latex; the filler A is 108 to 220 mesh quartz powder; and the filler B is 400 to 150 mesh mica powder. The aqueous filler for woodware of the invention contains no arene or alcohol ether and ether ester solution, avoids harm to the health of operators, uses water as a solvent and does not belong to dangerous chemicals. Therefore, the aqueous filler is safe and reliable in production, transportation and use.

Description

technical field [0001] The invention relates to a filler, in particular to a one-component filler for wood using water as a solvent. Background technique [0002] There are many types of fillers used in wood products today. Most of them are solvent-based fillers. Solvent-based fillers have excellent operability in large areas, but they contain aromatic hydrocarbons, alcohol ethers, and ether ester solvents, which are harmful to the health of operators and are likely to cause safety hazards such as fire. [0003] Water-based fillers, such as water ash, which are commonly used in the wood coating market today, can only be applied by scraping. The simple method of wiping is not easy to operate in large areas, which affects labor productivity. Contents of the invention [0004] The purpose of the present invention is to provide a water-based wood filler to overcome the above-mentioned defects in the prior art. [0005] Wood water-based filler of the present invention, its co...
