Abstract

The invention provides a water-based carpentry paint filler. The filler comprises the following raw material components in parts by weight: 33-53 parts of polyurethane emulsion, 4-12 parts of water, 0.2-1 part of cellulose, 0.2-1 part of a pigment filler dispersant, 0.1-1 part of a defoaming agent, 0.1-0.5 part of a pH additive, 5-25 parts of 800-mesh ground calcium carbonate, 12-40 parts of talcum powder, 2.5-10 parts of a coalescing agent, 2-8 parts of a polishing additive, 0.1-0.5 part of a bactericide and 0.1-3 parts of a thickener. The water-based carpentry paint filler provided by the invention is a carpentry paint filler which is high in solid content and good in filling property, avoids later-period collapse, is good in polishing property, reduces paint construction times, and is low in formulation cost and convenient in construction.

Description

technical field [0001] The invention relates to the field of furniture paint, in particular to a water-based wood paint filler and a preparation method thereof. Background technique [0002] At present, the base materials used in furniture on the market are mainly solid wood and solid wood veneer to reflect the natural texture of the furniture. Especially the boards of broad-leaved forests have clear and beautiful textures and are loved by most consumers. However, the broad-leaved forest board has deep texture and ducts, while the water-based wood paint has low solid content, poor filling performance, low hardness, and poor sanding performance. During the construction of wood paint, it needs multiple spraying and sanding. Filling the texture and ducts requires a high cost of manpower and material resources. [0003] On the furniture board, first apply a transparent primer or sealing primer, then spray the first transparent primer and polish; then spray the second transpare...
