Preparation method of wood product corrosion-resistant paint

Abstract

The invention discloses a preparation method of wood product corrosion-resistant paint. The wood product corrosion-resistant paint is prepared from the following raw materials in parts by weight: 20-25 parts of bisphenol-A epoxy resin, 15-20 parts of phenolic resin, 15-20 parts of alkyd resin, 15-18 parts of styrene, 4.5-6 parts of calcium carbonate, 7-8 parts of talcum powder, 7.5-10 parts of kaolin, 5-8 parts of bentonite, 7.5-9 parts of titanium dioxide, 0.01-0.05 part of a dispersing agent, 12-15 parts of a corrosion-resistant agent, 4.5-8 parts of a coalescing agent and 0.3-1 part of a defoaming agent. The corrosion-resistant agent is prepared in the process of preparing the wood product corrosion-resistant paint, the corrosion-resistant agent belongs to imidazolines, the imidazolineshave good corrosion resistance, meanwhile molecules of the corrosion-resistant agent contain hydrophilic groups and hydrophobic groups, the hydrophilic groups are attached to the surface of a wood product, a large number of the hydrophobic groups are located between the hydrophilic groups and the outside, absorption of water by the wood product is well isolated, corrosion of the wood product dueto being soaked in water for a long time is further prevented, and the service life of the wood product is prolonged.

Description

technical field [0001] The invention belongs to the field of paints, and in particular relates to a preparation method of corrosion-resistant paint for wood products. Background technique [0002] Wooden products are made of wood raw materials. After processing, the formed products have a short service life. Wooden products are usually painted with wood product paint to prolong the service life of wood products. The traditional wood product paint Corrosion resistance is average, and some wood product paints will cause uneven paint film thickness during the painting process and affect the appearance; [0003] Chinese patent CN105400259A discloses an anti-cracking environmental protection wood lacquer, which is composed of the following quality components: water-based acrylic emulsion 35-45%, methyl methacrylate 13-15%, hydroxyethyl acrylate 3-9% %, nano-calcium carbonate 5-7%, nano-silver antibacterial agent 4-6%, nano-calcium carbonate 5-7%, alumina particles 1-4%, animal a...

[0003] Chinese patent CN105400259A discloses an anti-cracking environmental protection wood lacquer, which is composed of the following quality components: water-based acrylic emulsion 35-45%, methyl methacrylate 13-15%, hydroxyethyl acrylate 3-9% %, nano-calcium carbonate 5-7%, nano-silver antibacterial agent 4-6%, nano-calcium carbonate 5-7%, alumina particles 1-4%, animal and vegetable oil composition 4-6%, diatomaceous earth 3-5% %, wax emulsion 0.1-0.4%, defoamer 0.4-0.8%, pH regulator 0.1-0.4%, anti-sedimentation agent 2.1-3.2%, dispersant 0.3-0.6%, film-forming aid 2-4%, attached Concentrate on 0.3-0.5% accelerator, 5-9% bamboo charcoal powder, 1-3% glass powder, and the balance is water; the invention can prevent wood products from cracking, and has strong adsorption to wood materials, is not easy to fall off, and is environmentally friendly and harmless to the body. The characteristics of harm, but the corrosion resistance of this invention is poor, and it will corrode the wood products when it is soaked in acid, alkali, organic solvent and water, which will affect the appearance and service life of the wood products
