Abstract

The invention relates to a water-based white sealed primer and a preparation method thereof. The water-based white sealed primer comprises the following components in part by weight: 350 to 600 parts of water-based resin and 50 to 100 parts of modified barium metaborate. The water-based white sealed primer provided by the invention has performance of sealing wood tannic acid and has a durable and good sealing effect after construction on the base material containing the tannic acid, nicotine blot and water-based pigment. Water-based white wood coating is coated on the primer, so the water-based white wood coating is not polluted by the pollutants and is not discolored, and the primer has high rubbing property, covering power and corrosion resistance and can prevent wood from being rotten and deteriorated.

Description

technical field [0001] The invention relates to the field of paint chemical industry, in particular to a water-based white sealing primer and a preparation method thereof. Background technique [0002] At present, white paint and white-based light-colored coating effects on the market have been recognized by consumers and have become the mainstream style in the decorative coating industry. White gives people the impression of purity, frankness and softness, and can remind people of holiness and innocence. White furniture, pure and elegant, reflects the distinctive style of the times, and white is the expression of a life philosophy. [0003] There are three kinds of conventional solvent-based paints commonly used at present: ordinary alkyd paint, polyurethane (PU) paint and nitro (NC) paint. Ordinary alkyd paints are prone to aging, cracking, and peeling off; polyurethane paints tend to turn yellow, and the decoration effect cannot last; while NC paints have low solid cont...
