Abstract

The invention discloses a waterborne transparent fire-proof coating for wood materials and a preparation method of the waterborne transparent fire-proof coating for the wood materials. The waterborne transparent fire-proof coating for the wood materials is prepared from the following raw materials which are taken as components in parts by weight: 45 to 55 parts of amino resin, 5 to 10 parts of polysiloxane emulsion, 25 to 30 parts of ammonium polyphosphate, 10 to 15 parts of pentaerythritol, 0.3 to 0.5 part of a thickener XS-167, 0.3 to 0.5 part of a light stabilizer UV1130, 0.3 to 0.5 part of an ultraviolet absorbent UV292, 0.3 to 0.5 part of dispersant SP-762, 0.3 to 0.5 part of a coalescing agent PPH, 0.3 to 0.5 part of a leveling agent XS-12, 0.3 to 0.5 part of a defoaming agent and an appropriate amount of deionized water. The waterborne transparent fire-proof coating for the wood materials disclosed by the invention is good in fireproof performance and transparent in coating, and can keep the original appearances of the wood materials, so as to be used in ancient buildings to restore the old as the old, and is further difficult to crack and good in weather resistance.

Description

Technical field [0001] The invention belongs to the technical field of architectural coatings, and in particular relates to a water-based transparent wooden material fireproof coating and a preparation method thereof Background technique [0002] In September 2015, the Ministry of Industry and Information Technology and the Ministry of Housing and Urban Construction jointly issued the "Action Plan on Promoting the Production and Application of Green Building Materials", which pointed out: "Develop wood structure buildings. Promote the application of wood structure buildings in cities and towns, and promote the use of wood structure buildings in government-invested schools and young Newly-built low-rise public buildings such as nursing homes, nursing homes, gardens and landscapes, and used in flat slopes in cities and towns.” The poor fireproof performance of structural members limits the promotion and use of wooden structures to a certain extent. Although wood fire retardant at ...
