Abstract

The invention discloses pinewood water-based oil-proof transparent primer as well as a preparation method and an application thereof. The pinewood water-based oil-proof transparent primer is formed by mixing components A with components B according to the mass ratio of 100:(5-15), wherein the components A consist of 60 to 70 percent of waterborne polyurethane-acrylic ester graft oil-proof copolymers, 15.6 to 24.6 percent of acrylic resin, 14 to 19 percent of water and 0.4 percent of additives, and the components B are polyfunctional aziridine solution. Paint films formed by the pinewood water-based oil-proof transparent primer have the characteristics of high compactness, resistance to corrosion of various kinds of organic solutions and chemical corrosion, water resistance, no toxicity and no odor, and in addition, grease can be efficiently sealed. The oil bleeding problem of pinewood products existing for a long time is thoroughly solved. In addition, the pinewood water-based oil-proof transparent primer adopts the water as diluting agent, so no volatile organic compounds (VOC) are released in the production and use processes, and the environment-friendly coating is really realized.

Description

technical field [0001] The invention relates to a water-based polyurethane paint, in particular to a special water-based oil-proof transparent primer for pine wood and its preparation method and application. Background technique [0002] The turpentine in pine wood is mainly composed of liquid turpentine and solid resin acid at room temperature. Because turpentine can dissolve solid resin acid, it has fluidity. When the temperature is low, resin acid is very viscous and difficult to flow, but with As the temperature increases, the viscosity of the resin acid decreases and will seep out of the wood surface. [0003] Currently commonly used pine primers include nitrolacquer (NC), which contains rosin esters or alkyd resins, and turpentine in pine is just the most suitable solvent for these resins. When the temperature rises, turpentine and other oily substances will drive straight into On the surface of the nitro-coated film, the disadvantages of the nitro-lacquer, such as ye...
