Embodiment Construction

[0030] Below in conjunction with embodiment the present invention is further described.

[0031] High-hardness, fast-polishing PU glossy wood varnish is characterized in that it includes component A, component B, and dilution components, and components A, component B, and dilution components are mixed in a weight percentage of 1:1:0.8, in;

[0032] The A component includes the following raw materials in weight percentage: 55% oil-free polyester resin I, 16% oil-free polyester resin II, 0.3% siloxane polymer, 0.5% acrylate polymer, 10% xylene, 17.7% butyl ester;

[0033] The B component includes the following raw materials in weight percentage: 66% TDI adduct, 33.5% butyl ester, 0.5% methyl ethyl ketone oxime

[0034] Described dilution component comprises the raw material of following percentage by weight: 60% dimethylbenzene and 40% butyl ester;

[0035] The chemical formula of the oil-free polyester resin I is:

[0036]

[0037] HO(CH2)nC(CH3)2CH2COOC6H10COOCH2CC2H5CH...

Abstract

The invention relates to high-hardness quick-polishing PU (Polyurethane) light wood paint. The high-hardness quick-polishing PU light wood paint comprises a component A, a component B and a diluent component, wherein the component A, the component B and the diluent component are mixed according to the weight percentage ratio of 1:1:0.8; the component A comprises the following raw materials in percentage by weight: 55 percent of oil-free polyester resin I, 16 percent of oil-free polyester resin II, 0.3 percent of a siloxane polymer, 0.5 percent of an acrylic ester polymer, 10 percent of xylene and 17.7 percent of butyl ester; the component B comprises the following raw materials in percentage by weight: 66 percent of a TDI (Toluene Diisocyanate) addition product, 33.5 percent of butyl ester and 0.5 percent of methyl ethyl ketoxime; and the diluent component comprises the following raw materials in percentage by weight: 60 percent of xylene and 40 percent of butyl ester. Through adoption of the high-hardness quick-polishing PU light wood paint, the bottleneck that packing and polishing cannot be finished within 48 hours is broken; the production efficiency of a wooden furniture production enterprise is increased; and overstocked products are reduced.

Description

technical field [0001] The invention relates to a wood furniture paint, which is mainly used in the field of wood furniture manufacturing, in particular to a high-hardness, fast-polishable PU bright wood paint and a preparation method thereof. Background technique [0002] At present, the wood furniture industry will use the PU gloss varnish, which is a two-component product, consisting of a main paint and a curing agent. The main paint is generally a synthetic fatty acid alkyd resin, and the curing agent is TDI or TDI. Trimer, the product is characterized by good fullness and high gloss, but it generally dries slowly, and it takes 48 hours to pack. If it is to be polished, it also takes more than 48 hours to reach the hardness that can be polished; if you adjust the curing agent, increase the The amount of trimer to achieve the desired drying speed, but at the expense of good fullness and high gloss performance. Therefore, in terms of dryness and hardness in the existing P...
