Problems solved by technology

[0003] Technical problems to be solved: adhesives have a wide range of applications. In environments involving high temperatures, higher requirements are placed on the peel strength of the adhesive at high temperatures. Adhesives whose peel strength drops sharply at high temperatures are not suitable for use at high temperatures. The high temperature resistance of conventional adhesives is poor, so new high temperature resistant adhesives and their preparation methods are needed

Abstract

The invention belongs to the field of the adhesives and discloses a high-temperature-resistant wood floor nano adhesive and a preparation method thereof. The nano adhesive is prepared from nano titanium dioxide, nano aluminium oxide, urea resin, verdyl acetate, ethyl laurate, methyl anthranilate, n-valeraldehyde and a silane coupling agent KH560. The preparation method comprises the following steps: (1) evenly mixing the two nano compounds, namely nano titanium dioxide and nano aluminium oxide, thereby obtaining powder A; (2) adding the urea resin, verdyl acetate, ethyl laurate and methyl anthranilate while stirring mechanically; (3) heating the mixture of the step (2) and then adding valeraldehyde, the silane coupling agent KH560 and the powder A prepared in the step (1), and mixing and stirring evenly to obtain the high temperature-resistant wood floor nano adhesive.

Description

technical field [0001] The invention belongs to the field of adhesives, and relates to an adhesive and a preparation method thereof, in particular to a high-temperature-resistant wooden floor nano-adhesive and a preparation method thereof. Background technique [0002] At present, the application of adhesives has penetrated into various fields of the national economy. On many occasions, adhesives can effectively replace welding, riveting, screwing and other mechanical connections, simplifying processes, saving energy, reducing costs, and increasing production costs for each production front. Economic benefits provide an effective way. With the rapid development of science and technology, higher and higher requirements are put forward for the performance of adhesives and bonding technology. There are many ways to classify adhesives. According to the application method, they can be divided into thermosetting type, hot melt type, room temperature curing type, pressure sensitiv...
