Problems solved by technology

[0003] However, since the main material of wood-based panels is wood particles or fibers, there are many gaps and voids, and the structure is loose. After absorbing moisture in the air, the edges are prone to expansion in the thickness direction, and even mildew, which seriously affects subsequent processing.
[0004] At present, paraffin wax and its similar products are mainly used in the market to deal with the above-mentioned expansion and mildew phenomenon, but the effect is very small, and the problem of edge expansion cannot be fundamentally solved

preparation example Construction

[0040] The present invention has no special requirements on the preparation method of the surface sealing agent, and the surface active agent, acrylic resin water-soluble organic matter, nano-microcapsule paraffin wax emulsion and antifungal agent can be mixed in any order.

[0041] The surface sealing agent obtained in the present invention is a milky white liquid with a pH value of 7-8.

[0042] The invention also provides a method for using the surface sealing agent, which comprises coating the surface sealing agent on the surface to be treated and drying it.

[0043] The present invention has no special requirements on the specific method of finishing, which may be hand coating, dip coating or brush coating. In the present invention, the coating dosage of the surface sealing agent is preferably 300-400 g / m 2 , more preferably 320-380g / m 2 , most preferably 340-360g / m 2 .

[0044] In the present invention, the drying temperature is preferably 60-100°C, more preferably 7...

Embodiment 1

[0048] Mix 10 parts of surfactant, 60 parts of acrylic resin water-soluble organic matter, 20 parts of nano-capsule paraffin wax emulsion and 1 part of antifungal agent, and paint on the fiberboard with a brushing amount of 400g / m 2 . The painted fiberboard was dried at 60° C. for 3 minutes.

[0049]In the present invention, the dried fiberboards in Example 1 and the fiberboards coated with commercially available sealant #1 and commercially available sealant #2 were soaked in water for four weeks at room temperature, and the thicknesses of the edges of the three boards were tracked. The detailed expansion rate is shown in Table 1. The commercially available sealant #1 is Black Gold Steel (batch number 20160419), and the commercially available sealant #2 is Honglian (20160423).

[0050] Table 1 Example 1 provides surface sealant and commercially available sealant to handle the immersion expansion rate of fiberboard

[0051] Type of sealant one day a week two w...

Embodiment 2

[0063] Mix 20 parts of surfactant, 70 parts of acrylic resin water-soluble organic matter, 10 parts of nano-microcapsule paraffin wax emulsion and 0.5 part of antifungal agent, and paint on the blockboard with a brushing amount of 300g / m 2 . The painted fiberboard was dried at 100° C. for 1 minute.

[0064] The test is carried out according to the experimental method of the example, and the test result shows that the expansion rate of the fiberboard treated with the surface sealant provided by Example 2 is 0.41% after four weeks.

Abstract

The invention provides a surface sealing agent and a use method thereof. The surface sealing agent provided by the invention comprises 10-20 parts of a surfactant, 60-70 parts of an acrylic resin water soluble organic matter, 10-20 parts of a nano microcapsule paraffin emulsion and 0.1-1 part of a mildew inhibitor. According to the result of the embodiment, the surface sealing agent provided by the invention has excellent anti-swelling and anti-mildew properties. The expansion ratio of a fiber board in four weeks is just 0.4% which is far lower than 1.33% and 1.95% of the sealing agents sold in the market. Slight mildewing happens on the 30th day, and the mildewing time is greatly prolonged.

Description

technical field [0001] The invention relates to the technical field of surface treatment agents, in particular to a surface sealing agent and its application method. Background technique [0002] Wood-based panels are boards or molded products that are made of wood or other non-wood plants, separated into various unit materials by certain mechanical processing, and glued with or without adhesives and other additives, mainly including plywood , shaving (particle) board and fiberboard three categories of products, its extension products and deep processing products amount to hundreds of kinds. [0003] However, since the main material of wood-based panels is wood particles or fibers, there are many gaps and voids, and the structure is loose. After absorbing moisture in the air, the edges are prone to expansion in the thickness direction, and even mildew, which seriously affects subsequent processing. . [0004] Currently on the market, paraffin wax and its similar products a...
