Problems solved by technology

In the furniture coating market, American-style painted furniture occupies a relatively large market share. Most of the domestic furniture industry uses color essence (a metal complex dye, such dyes have serious problems such as heavy metals exceeding the standard, containing pathogenic substances, temperature resistance, Poor light fastness and migration resistance, commonly known as Grace) for wood grain wiping and varnishing colorants, most of the resins used for wiping are ordinary alkyd resins and linseed oils, and the furniture still remains for a long time after painting. Odor; today's huge wood paint market has higher and higher requirements for paint products. Especially wood polyurethane (PU) paint has excellent comprehensive performance and is widely used by consumers, but there are many shortcomings in the product, such as whitening and blistering , delamination, non-scratch resistance, ghosting, fingerprints are not easy to disappear, etc.

Embodiment 1

[0024] According to the formula weight ratio, add 22.5 parts of mixed solvent into the dispersion tank, add 55 parts of 70% solid-containing alkyd resin, add 6 parts of TEGO-610 color paste dispersant and stir evenly, slowly add 16 parts of translucent light maple wood Color calcined raw powder, 0.2 part of defoamer, 0.3 part of anti-sedimentation agent, then disperse at a high speed of 1000-1200r / min for 45-60 minutes, and then go to a horizontal sand mill to grind 5-8 times until the color paste The fineness and particle size meet the requirement of ≤5μ, move to the paint mixing tank for defoaming and viscosity adjustment, filter and pack to obtain light maple color paste.

Embodiment 2

[0026] According to the formula weight ratio, add 16 parts of mixed solvent into the dispersion tank, add 65 parts of 70% solid-containing alkyd resin and stir evenly, add 2 parts of matting powder, 0.3 parts of dispersant, disperse at high speed for 30-40 minutes, and stir at low speed Add 15 parts of light maple color paste, 0.3 parts of titanate-modified silicone chelating leveling agent, 0.2 parts of fluorine-modified acrylic leveling agent, 0.2 parts of modified silicone defoamer, and 1 part of anti-settling agent After being stirred and passed the test, filtered and packaged, the first component of translucent light maple color calcined sodium-cleaning polyurethane wood lacquer is obtained.

Embodiment 3

[0028] Add 40 parts of TDI / TMP adduct, 30 parts of HDI trimer, and 30 parts of mixed solvent into the dispersion tank and stir evenly. After passing the test, filter and pack to obtain translucent light maple color calcined na-taste polyurethane Part B of wood lacquer.

[0029] Mix the paint according to the ratio of component A: component B = 1:0.5, and add thinner to adjust the viscosity to spray or brush.

Abstract

The invention relates to a translucent light maple-colored calcined and clean-smelling polyurethane wood lacquer and a preparation method thereof. Alkyd resin, matting powder, dispersant, light maple color paste, leveling agent, defoamer, anti-settling agent and solvent; component B is composed of TDI, HDI trimer or adduct-based benzene-free Curing agent; the translucent light maple color calcined and taste-cleaning type polyurethane wood lacquer prepared by the present invention does not contain aromatic hydrocarbons, aldehydes and ketones, and heavy metals, and reaches the effect of cleansing taste after 48 hours of film formation; and No sedimentation during storage, good fluidity, good hand feeling, high scratch resistance, no ghosting; the wood grain is clear and thorough when painted on wood, making the furniture look elegant, noble, simple and natural, giving people an elegant and comfortable feeling, adapting to modern times Its aesthetics are favored by the market and loved by customers. Widely used in wood, metal, plastic and other surface decoration and protection.

Description

technical field [0001] The invention relates to a preparation method of a two-component polyurethane wood finish, in particular to an anti-scratch two-component polyurethane wood finish with a translucent light maple color calcined and clean taste. Background technique [0002] With the improvement of people's material and cultural living standards, consumers have higher and higher requirements for the coating effect of furniture, which has led to the rapid growth of domestic wood coatings. In the furniture coating market, American-style painted furniture occupies a relatively large market share. Most of the domestic furniture industry uses color essence (a metal complex dye, such dyes have serious problems such as heavy metals exceeding the standard, containing pathogenic substances, temperature resistance, Poor light fastness and migration resistance, commonly known as Grace) for wood grain wiping and varnishing colorants, most of the resins used for wiping are ordinary al...
