For traditional household glue, there is always aldehyde, which leads to a pungent smell in the room after home decoration for a period of time, which seriously affects people's health.
[0003] There are many problems in the currently used viscose glue, such as high viscosity of bean glue, which cannot be sprayed at all, low solid content, high water content, and cannot be cured by hot pressing in a short time; isocyanate glue sticks too badly to the guide plate of the press machine , can not be operated, even if demoulding can be operated, it is too time-consuming and laborious, and the production cost is increased. At the same time, its own cost is too high, and it is a toxic and harmful substance and is not environmentally friendly. The so-called formaldehyde-free industry

Abstract
The invention discloses glue. The glue comprises urea resin, polyimide, ethylacrylic acid ester and polyurethane. A weight ratio of the urea resin to the polyimide to the ethylacrylic acid ester to the polyurethane is 2-4:1-3:2-3:2-6. The glue has the advantages that the glue is made of natural biological raw materials and is free of formaldehyde release, applicable to shaving board processing technologies, excellent in the bonding strength and nail holding power and good in machining performance, and the traditional aldehyde-containing glue is completely replaced.
Description
technical field [0001] The invention relates to the technical field of household glue, in particular to a kind of glue. Background technique [0002] Viscose is often used in existing home decoration, which is convenient and fast to use, and is stable and widely used. For traditional household glue, there is always aldehyde, which leads to a pungent smell in the room after home decoration for a period of time, which seriously affects people's health. [0003] There are many problems in the currently used viscose, such as high viscosity of bean glue, which cannot be sprayed at all, low solid content, high water content, and cannot be cured by hot pressing in a short time; isocyanate glue sticks too badly to the guide plate of the press machine , can not be operated, even if demoulding can be operated, it is too time-consuming and laborious, and the production cost is increased. At the same time, its own cost is too high, and it is a toxic and harmful substance and is not env...
