Problems solved by technology

The problems of solvent-based nitro paint / polyurethane paint are: (1) Contains harmful ingredients, such as "triphenyl" (benzene, toluene, xylene), or TDI, formaldehyde, polycyclic aromatic hydrocarbons or Eight heavy metals (Cd, Pb, Hg, Cr, Ba, Se, As, Sb); (2) When the external temperature and humidity changes, the coating of wood products can adjust the internal ventilation poorly, and it is prone to expansion deformation and cracking.
(3) The coating is surface-covering type, and the paint film will peel off or be scratched in the event of collision and friction; while ordinary wood wax oil is coated with slow drying speed, low hardness of the dry film of the coating, and poor wear resistance

Abstract

The invention discloses a nano silicon dioxide modified hard wood wax oil and a preparation method thereof. The invention aims to overcome the defects of low drying speed and low hardness in the existing wood wax oil, and to be applied to furniture application instead of common wood wax oil or nitrocellulose paint/polyurethane paint. The product comprises the following raw materials in percentage by weight: 35-45% of modified hard tung oil or linseed oil, 15-25% of carnauba wax of which the softening point is 85-95 DEG C, 15-25% of linseed oil long oil alkyd of which the oil length is 78-80% and the solid content is higher than 98%, 3-5% of nano silicon dioxide of which the particle size is 60-80 nm, 20-30% of decyclized aromatic hydrocarbon of which the distillation range is 160-200 degrees, 1-2% of isooctoate compound drying agent and 0.3-0.5% of methylethylketoxime. The preparation method comprises the following steps: preparing a material A, preparing a material B, and mixing the material A and the material B.

Description

technical field [0001] The invention relates to a coating used on wood products and a production method thereof, and is characterized in that it is an environment-friendly high-solid content coating used on wood products and a production method thereof. Background technique [0002] my country's "Twelfth Five-Year Plan for the Coatings Industry" points out that the focus and direction of the structural adjustment of the coatings industry is to encourage environmentally friendly and resource-saving coatings - water-based coatings, high-solid coatings, solvent-free coatings, radiation-curing coatings, etc. However, ordinary wood wax oil or solvent-based nitro / polyurethane furniture paint is mostly used for wood product coating. The problems of solvent-based nitro paint / polyurethane paint are: (1) Contains harmful ingredients, such as "triphenyl" (benzene, toluene, xylene), or TDI, formaldehyde, polycyclic aromatic hydrocarbons or Eight heavy metals (Cd, Pb, Hg, Cr, Ba, Se, As...
