Problems solved by technology

At present, the color in furniture production and painting is made of color correction agent or color correction essential oil plus color essence, and the drying time is longer
In the painting process, the water-based color correction agent can only be applied to the water-based topcoat after it is dry, which greatly affects the painting efficiency and prolongs the time for finished furniture products to go off the assembly line and enter the market.
During the painting process of the automatic assembly line of furniture, the topcoat must be sprayed after the color is repaired (commonly known as the "wet-on-wet" process). Problems such as blooming, oil leakage, and poor adhesion often occur, and it cannot meet the requirements of UV-based water-based surfaces, PU Water-based surface and other process coating

Abstract

The invention discloses a water-based color repairing agent used in furniture and woodware production industries. The water-based color repairing agent is composed of the following raw materials in parts by weight: 15-20 parts by weight of water-based polyurethane resin, 0.1-0.5 parts by weight of pH regulator, 0.1-0.3 parts by weight of water-based wetting agent, 0.1-0.3 parts by weight of water-based defoamer, 0.1-0.3 parts by weight of water-based thickening rheological agent, 3.0-5.0 parts by weight of co-solvent, 0.1-0.2 parts by weight of silane coupling agent, 70-80 parts by weight of hydrophilic solvent, 1-10 parts by weight of water. The invention has simple formula composition, simple production process, low economic cost, no need to add or change the original production equipment, and the invented product has quick drying, good adhesion, good color matching, can be "wet on wet" construction, and has a wide range of applications, etc. Features, meet the assembly line coating requirements, suitable for industrialized mass production.

Description

technical field [0001] The invention relates to the field of coatings, in particular to the field of water-based varnishes used for furniture and woodware. Background technique [0002] Due to the further restrictions on VOC emissions of coatings by the national environmental protection policy, water-based coatings are used more and more in wood coatings due to their environmental protection and low VOC emissions. At present, the color in the production and painting of furniture is made of color correction agent or color correction essential oil plus color essence, and the drying time is longer. In the painting process, the water-based color correction agent can only be applied to the water-based topcoat after it is dry, which greatly affects the painting efficiency and prolongs the time for finished furniture products to go off the assembly line and enter the market. During the painting process of the automatic assembly line of furniture, the topcoat must be sprayed after ...
