Abstract

The invention relates to a high-construction-performance polyurethane (PU) paint which is prepared by using main aggregates of alkyd resin, nitrocellulose, and a modified TDI curing agent. The paint has good construction performance. The paint is prepared from the components of: alkyd resin, nitrocellulose, titanium dioxide, talc, an organic solvent, a surfactant, a siccative, an anti-settling agent, and the modified TDI curing agent. With the components, the prepared PU paint has advantages of high surface drying speed. Under a natural environment, after 50min of natural drying, obtained materials can be fetched, and can be stacked and stored. The paint can be used for batched machine-stage on-line production, and provides good adhesive force for coated topcoat. During a drying early-stage, most of cross-linking reactions are fast. During a drying late-stage, the reactions are relatively slow, such that topcoats have certain dissolving capacity and good adhesive force for primers. A paint film has good flexibility and sealing ability, and is suitable for both soft and hard base materials. Especially, the paint film has good sealing ability for density boards, and assists in preventing oil-emitting or non-drying phenomena during a drying process. The paint provided by the invention is suitable for large-scale machine-stage productions of various solid wood furniture and board furniture.

Description

technical field [0001] The invention relates to a paint with high construction performance, in particular to a polyurethane colored primer. Background technique [0002] At present, the competition in the furniture industry is fierce. With the increase of the cost of raw materials and labor, the profits of the furniture industry are gradually declining. A series of ways to reduce costs, such as the improvement of production efficiency and the replacement of labor by automatic production lines, have gradually become the goals pursued by various furniture industries. This demand requires the coating to have higher construction performance and good environmental applicability. This product can improve production efficiency and is suitable for different construction techniques and different environments. Polyurethane coatings in the prior art, such as a vegetable oil-based environment-friendly bright floor paint disclosed in the invention patent of Chinese Patent No. 2009101607...
