Problems solved by technology

Such as pigment-based colorants, good coloring effect, excellent workability, but poor filling effect
Water-based putty, oil-based putty, and nitro putty have good filling performance, poor coloring, and poor operability in large areas
Two-component polyurethane putty and unsaturated polyester putty have good filling properties, poor coloring properties, poor operability in large areas, and have aging problems. Moreover, the above-mentioned types of putty can only be applied by scraping, which greatly reduces the Labor productivity

Embodiment 1

[0042] Components and parts by weight:

[0043] 8 parts of polyethylene resin, 24 parts of S-100 solvent, 1 part of bentonite, 65 parts of 200 mesh quartz sand, 2 parts of linseed oil.

[0044] First dissolve polyethylene resin with S-100 solvent, stir, add bentonite, then add 200 mesh quartz sand, disperse fully, add linseed oil, and stir evenly.

[0045] Wipe or scrape this product on boards with deep wood grains such as oak or ash, wipe it clean, and after drying, the polisher directly sprays PU primer twice, PU topcoat once; or paint three times One base primer, one nitro top coat. All products can achieve full sealing effect. After 48 hours, the adhesion is tested by the 100-grid method, and the adhesion is grade 1. This product is unpainted.

Embodiment 2

[0047] Components and parts by weight:

[0048] 8 parts of polyethylene resin, 23 parts of S-100 solvent, 1 part of bentonite, 1 part of dispersant, 5 parts of transparent iron oxide brown, 60 parts of 200 mesh quartz sand, 2 parts of linseed oil;

[0049] The dispersant is a high molecular weight acrylic block copolymer solution, preferably EFKA4401 or BYK-2000, such as EFKA-4401 from EFKA in the Netherlands;

[0050] First dissolve polyethylene resin with S-100 solvent, stir, add bentonite, then add dispersant, add transparent iron oxide brown sand to grind to fineness ≤ 10 microns, then add 200 mesh quartz sand, disperse fully, add linseed oil, stir uniform.

[0051] Wipe or scrape this product on boards with deep wood grains such as oak or ash, wipe it clean, and after drying, the polisher directly sprays PU primer twice, PU topcoat once; or paint three times One base primer, one nitro top coat. All products can achieve full sealing effect. After 48 hours, the adhesion ...

Abstract

The invention provides a wood filling agent, which comprises components in weight portion as follows: 6 to 10 portions of polyethylene resin, 20 to 30 portions of solvent, 1 to 2 portions of anti-settling agent, 60 to 70 portions of filler and 1 to 5 portions of linseed oil. The wood filling agent has excellent interlayer adhesion and good filling performance, and can save 1 or 2 times of coating polyurethane (PU) with quick drying; and the wood with the wood filling agent can be polished after 15 minutes at a normal temperature of 25 DEG C. With excellent large-scale operation, the wood filling agent can adopt a plurality of construction ways such as rubbing or scrapping and has even wood coloring, thereby greatly improving labor productivity.

Description

technical field [0001] The invention relates to a filler, in particular to a one-component filler for woodware. Background technique [0002] There are many varieties of wood conduit staining and filling used in carpentry products today. Such as pigment-type colorants, the coloring effect is good, the workability is excellent, but the filling effect is poor. Water-based putty, oil-based putty, and nitro putty have good filling performance, poor coloring, and poor operability in large areas. Two-component polyurethane putty and unsaturated polyester putty have good filling properties, poor coloring properties, poor operability in large areas, and have aging problems. Moreover, the above-mentioned types of putty can only be applied by scraping, which greatly reduces the Labor productivity. Contents of the invention [0003] The purpose of this invention is to provide a wood filler to overcome the above-mentioned defects in the prior art. [0004] Wood filler of the prese...
