A high-solid, low-viscosity, fast-drying and clean-tasting alkyd resin, its preparation method and application

Abstract

The invention discloses high-solid, low-viscosity and quick-drying odor removal alkyd resin, a method for preparing the same and application of the high-solid, low-viscosity and quick-drying odor removal alkyd resin. The high-solid, low-viscosity and quick-drying odor removal alkyd resin in a formula comprises, by weight, 15-20 parts of oleic acid, 2-4 parts of 3, 5, 5-trimethyl hexanoic acid, 2-4 parts of 2-ethylhexanoic acid, 2-4 parts of castor oil, 25-32 parts of polyacid, 18-26 parts of polyols, 3-5 parts of reflux solvents, 17-21 parts of diluting solvents and 0.5-2 parts of auxiliaries. The high-solid, low-viscosity and quick-drying odor removal alkyd resin, the method and the application have the advantages that the high-solid, low-viscosity and quick-drying odor removal alkyd resin has quick-drying and odor removal characteristics, the solvents can be quickly released when the high-solid, low-viscosity and quick-drying odor removal alkyd resin is coated, the high-solid, low-viscosity and quick-drying odor removal alkyd resin in construction sites rarely has odor and can be completely dried after being coated for 24 h, dried paint films hardly have odor, and people can hardly smell out smell and can have a sense of joy just like a sense of joy under the condition of water-based paint films; the solid content of the high-solid, low-viscosity and quick-drying odor removal alkyd resin prepared by the aid of the method is 80+ / -2%, the viscosity of the high-solid, low-viscosity and quick-drying odor removal alkyd resin is 10000+ / -2000 mpa.s / 25 DEG C, accordingly, the high-solid, low-viscosity and quick-drying odor removal alkyd resin has high-solid and low-viscosity characteristics, the usage of diluents can be reduced when paint is prepared, the VOC (volatile organic compounds) content can be reduced and is only 350 g / L after the paint is manufactured, and tax exemption requirement on construction VOC content lower than 420 g / L after the paint is manufactured can be sufficiently met.

Description

technical field [0001] The invention relates to an alkyd resin for wood lacquer coating, in particular to a high-solid, low-viscosity, quick-drying and clean-odour alkyd resin, a preparation method and application thereof. Background technique [0002] The coating made of hydroxyl-containing alkyd resin has the advantages of good film adhesion, high hardness, good leveling, bright, plump, and good chemical resistance. Compared with other resins (such as nitrocellulose, epoxy resin, acrylic resin, etc. Resin, polyurethane resin, amino resin, etc.) can be formulated into a variety of coatings with different properties to play a decorative and protective role. Coatings made of hydroxyl-containing alkyd resins are the main types of wood lacquer coatings, accounting for about 40% to 50% of the total wood lacquer coatings. Alkyd resin has easy-to-obtain raw materials, simple process, excellent compatibility, convenient construction, superior performance, and meets the social requ...

AI Technical Summary

Problems solved by technology

[0004] In conventional wood coating products, a certain amount of solvent is contained, and the solvent itself has its own characteristic smell. Senses cause greater stimulation, affecting the environment of the painting site and the health of construction workers

In addition to the smell caused by the solvent, the paint film after painting will also have more or less smell, which cannot give people a pleasant feeling
