Problems solved by technology

The fullness, hardness, and flexibility of this polyurethane paint are poor, and if it is painted only once, it will not be able to meet the requirements of the furniture's feel and fullness; because of its poor dryness and hardness, if it is painted multiple times, it will prolong the life of the furniture. The shipping time also increases the manpower and material cost of the furniture factory

Embodiment 1

[0049] 1) Preparation of anti-settling slurry:

[0050] Prepare raw materials according to the following mass percentages;

[0051] Fatty acid short oil alkyd resin 40%

[0052] Propylene glycol methyl ether acetate 20%

[0053] Polyamide wax 20%

[0054] Xylene 20%;

[0055] The fatty acid short oil alkyd resin is a resin produced by DSM Synthetic Resin (Foshan) Co., Ltd. (model: 2510X80C, solid content: 80%);

[0056] The polyamide wax is produced by Kusumoto Chemical (model: 6900HV, solid content: 20%);

[0057] Production process: Choose a clean and meet the requirements of the dispersion tank, put in fatty acid short oil alkyd resin, propylene glycol methyl ether acetate, stir evenly at 600-800 revolutions per minute, and put in polyamide wax at 600-800 revolutions per minute. Disperse at a minute speed to the fineness ≤ 25μm, stop adding xylene, stir evenly at a speed of 600-800 revolutions per minute, and then pack it into a barrel for later use.

Abstract

The invention relates to a PU high-fullness matte varnish for melamine boards, which belongs to the technical field of wood coating manufacturing. The PU high-fullness matte varnish for melamine boards of the present invention is composed of components A, B and C according to the weight ratio of 1:0.5:0.5-0.7; wherein component A is composed of fatty acid short oil alkyd resin, hydroxyacrylic acid Resin, xylene, wetting and dispersing agent, defoamer A, defoamer B, anti-settling slurry, matte powder, wax powder, leveling agent A, leveling agent B, adhesion promoter, cyclohexanone and n-butyl ester Composition; B component is composed of TDI trimer curing agent, TDI prepolymer, HDI trimer curing agent, xylene and n-butyl acetate; C component is composed of xylene, n-butyl acetate, propylene glycol methyl ether acetate It is composed of ester, cyclohexanone, and ethylene glycol diacetate; it significantly improves the fullness, adhesion, yellow resistance, and flexibility of matte clear topcoats. The PU high-fullness matte clear finish paint for melamine boards of the present invention can be directly sprayed on melamine boards.

Description

Technical field [0001] The invention relates to a PU high-fullness matte varnish for melamine board, which belongs to the technical field of wood coating manufacturing. Background technique [0002] Melamine board, melamine board for short, prefers to be called ecological board in the industry. The full name is melamine impregnated adhesive film paper veneer wood-based board. Melamine board is also called double veneer board, paint-free board, ecological board, and some people call it one-time forming board. Its base material is particle board and medium fiber board, which is made by bonding the base material and the surface. The surface is soaked in melamine resin adhesive with paper with different colors or textures, and then dried to a certain degree of curing, and then laid It is a decorative board that is installed on the surface of particleboard, moisture-proof board, medium density fiberboard, plywood, blockboard or other hard fiberboard, and is heated and pressed. The su...
