Description
Technical field
The present invention relates to a kind of double-component aqueous wood paint, preparation method and constructional method thereof, be specifically related to a kind of acid catalysis double-component aqueous wood paint, preparation method and constructional method thereof.
Background technology
Aqueous woodware paint developed rapidly in recent years, along with the continuous development of resin synthetic technology makes the performance of aqueous woodware paint also increase.Difference by film forming mechanism can be divided into aqueous woodware paint common on the present market two big classes: single-component water-based wood lacquer and dual-component polyurethane aqueous woodware paint.As the patent publication No. of announcing on March 2nd, 2005 is that CN1587331A, denomination of invention are the Chinese invention patent of " water-based mono-component polyurethane carpentry paint and manufacture method thereof ", it discloses a kind of aqueous one-component polyurethane carpentry paint, and the contriver has given prominence to the open effect that it had and the advantage of environmental protection aspect.As the patent publication No. of announcing on February 23rd, 2005 is that CN1583916A, denomination of invention are the Chinese invention patent application of " aqueous double-component polyurethane wood lacquer and preparation method thereof ", it discloses a kind of aqueous double-component polyurethane wood lacquer, the contriver has improved use properties, overcome the defective that traditional double component lacquer must use up the short period of time thereby make the serviceable time prolong, otherwise gel can take place the paint that mixes up can't use, thereby wasting present situation.Single-component water-based wood lacquer is easy to use directly can be brushed or spray by the water dilution, but its mechanical property and chemical resistance are relatively poor.The dual-component polyurethane aqueous woodware paint is because the reaction of water-base resin and water-based polymeric polyisocyanate makes paint film property that obvious lifting be arranged, but because its reaction is slow, waits that the time of doing is long, influenced user's production efficiency greatly.Because moisture for a long time in the paint film, a part of water-based polymeric polyisocyanate can make final paint film property descend with the water reaction simultaneously.In addition, because the synthetic technology of water-based polymeric polyisocyanate is grasped in a few transnational company's hand, its price is high, has had a strong impact on double-component aqueous wood paint popularization at home.The present invention is improved aqueous woodware paint from many-sides such as cost, efficient, performances.
