Embodiment 1

[0023] According to the formula weight ratio, add 25 parts of mixed solvent into the dispersion tank, add 50 parts of 60% solid alkyd resin, add Stir 9 parts of 4320 carbon black dispersant evenly, slowly add 15 parts of special 4 carbon black, then disperse at a high speed of 1000~1200r / min for 45~60min, and then grind 4~6 times in a horizontal sand mill until the color The fineness and particle size of the pulp meet the requirement of ≤10μ, and it is transferred to the paint mixing tank for defoaming and viscosity adjustment, and then filtered and packaged to obtain solvent-based carbon black pulp.

Embodiment 2

[0025] Add 40 parts of 60% solid alkyd resin, 15 parts of 70% solid hydroxyl acrylic resin, 8 parts of 60% solid aldehyde and ketone resin, and 11 parts of mixed solvent into the paint bucket. Add 25 parts of the above ground carbon black slurry, add 0.2 parts of titanate modified silicone leveling agent, 0.1 part of silicone modified acrylic leveling agent, 0.2 parts of antioxidant, modified siloxane disinfectant at low speed 0.2 part of foaming agent, 0.3 part of fumed silicon dioxide, stirred and tested, filtered and packaged to obtain anti-scratch two-component polyurethane wood gloss black finish A component.

Embodiment 3

[0027] 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 prepare the second component of anti-scratch polyurethane wood glossy black finish.

[0028] Mix the paint according to the ratio of component A: component B = 1:0.5, and add thinner to adjust the viscosity to be brushable.

Abstract

The invention relates to a preparation method of a scratch resistant polyurethane woodenware glossy black finish paint. The finish paint is composed of a resin paint component A and a curing agent component B; wherein the weight ratio of the component A to the component B is 1:0.5; the resin paint component A is composed of alkyd resin, acrylic resin, aldehyde-ketone resin, carbon black color paste, a chelating leveling agent, an antifoaming agent, an anti-settling agent, and a solvent; and the curing agent component B is composed of a TDI-HDI mixed trimer or a TDI / TMP adduct, a HDI trimer, and a solvent. The prepared finish paint has the advantages of high hardness, low viscosity, and good leveling property. The finish paint can form a membrane at a time, the membrane is thick, and no sag is generated. The paint has high gloss and a transparent crystal appearance like a black jade. The paint membrane is like a crystal, is thick and smooth, gives people a high quality sense, has a decoration effect like a mirror, and creates a fresh, grace, concise, and tranquil space. A refreshing unique feeling is created by the finished paint which is accord with the modern aesthetics, so the finish paint is welcomed by market and customers. The finish paint can be used to decorate and protect the surfaces of woodenware, metal products, and plastic products.

Description

technical field [0001] The invention relates to a preparation method of a two-component polyurethane gloss black finish for woodware, in particular to an anti-scratch polyurethane glossy black finish for woodware. 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. The coating effect of the furniture surface will directly affect consumers' choice of furniture, and matt wood coatings occupy a large market share in the furniture coating market. 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. However, the product has many shortcomings, such as whitening, foaming, and peeling. layer, not resistant to scratches, ghosting, fingerprints are ...
