Biological environment-friendly frosted wooden coating and preparation method

Abstract

The invention relates to the technical field of coatings, in particular to a biological environment-friendly frosted wooden coating and a preparation method. The biological environment-friendly frosted wooden coating is prepared from substances in parts by weight as follows: 60-100 parts of waterborne polyurethane, 15-30 parts of hard shells, 20-40 parts of soft shells, 5-10 parts of a surfactant,5-10 parts of quaternary ammonium salt, 3-8 parts of phosphate, 5-12 parts of shellac, 5-15 parts of a filling agent, 3-12 parts of a silane coupling agent, 1-8 parts of a defoaming agent, 2-8 partsof a thickening agent, 1-3 parts of a preservative and 120-180 parts of water. According to the coating, the hard shells and the soft shells are compounded, so that compatibility of shell powder and acoating substrate is improved, good three-dimensional frosted effect is also achieved, the coating is ecological and environmentally friendly and touches comfortable and natural, and coating layers are combined tightly without cracking or delaminating.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a bio-environmental protection frosted wood coating and a preparation method. Background technique [0002] Wood coatings refer to coatings used on equipment made of solid wood boards, wood grain panels, glue boards, chipboards, fiberboards, etc., including paints for furniture, floors, stationery, musical instruments, and building decoration materials. Roughly divided into two categories, one is used in furniture factories, and the other is used in interior decoration. [0003] At present, the main varieties of wood coatings (including furniture and interior decoration coatings) are nitro lacquer (NC), polyurethane coating (PU), unsaturated polyester coating (PE), amino alkyd coating (AC, referred to as acid curing coating). ), UV-curable coatings (UV) and water-based coatings, etc. During the production and use of solvent-based wood coatings, a large amount of water volatili...

AI Technical Summary

Problems solved by technology

[0006] Aiming at the defects of single decorative color, varnish pollution, and weak three-dimensional effect of existing wooden paint furniture, in order to make the paint have a woody frosted feeling, the present invention proposes a biologically environmentally friendly frosted wood paint and a preparation method, which has a good frosted three-dimensional effect , ecological and environmental protection, and does not affect the wooden effect of wooden furniture, feels comfortable and natural, and the coating layer is tightly bonded without cracking or delamination
