Abstract
The invention discloses a modified urea-formaldehyde resin adhesive which is mainly prepared from the following raw materials in parts by weight: 100 parts of modified urea-formaldehyde resin, 15-25 parts of organophosphate, 4-10 parts of wood dust powder, 3-7 parts of pentaerythritol, 4-12 parts of talcum powder, 4-12 parts of kaolin, 10-20 parts of magnesium hydroxide and 2-8 parts of starch. The invention also discloses a preparation method of the modified urea-formaldehyde resin adhesive. Compared with the prior art, the modified urea-formaldehyde resin adhesive disclosed by the invention has the advantages of obviously higher binding strength, excellent adhesive property and obviously lower free formaldehyde content, and can effectively reduce the environmental pollution.
Description
Technical field
The present invention relates to a kind of sizing agent and preparation method thereof, be specifically related to a kind of modified urea-formaldehyde resin glue and stick agent and preparation method thereof, be widely used in the industry such as production and interior decoration of woodenware processing, glued board, shaving board, wood-based plate.
Background technology
At present, the use of sizing agent is more and more extensive, and demand is also increasing, and it is widely used in the industries such as woodenware processing, glued board, shaving board, the production of wood-based plate and interior decoration.Along with the fast development of China's economic construction, the requirement for sizing agent is also more and more higher, not only requires that it has more excellent gluing performance, and reduces that it is also more important to the pollution of environment.
Urea-formaldehyde resin (UF resin) be urea and formaldehyde under catalyzer (alkalescence or an acidic catalyst) act on, polycondensation becomes initial stage urea-formaldehyde resin, and then under solidifying agent or promoter effect, forms resin in latter stage that is insoluble, that do not melt.Urea-formaldehyde resin is one of maximum resin of market demand, because its raw material is cheap and easy to get, manufacturing process is simple, first viscosity large, cohesive strength advantages of higher, is widely used in the industries such as woodenware processing, the production of artificial board and interior decoration.
But, but along with people are to the expansion of raising and sizing agent Application Areas day by day that indoor environment is realized, the subject matter that tackiness agent exists also exposes out: as adhesive property is poor, free formaldehyde content is higher, causes environmental pollution, infringement HUMAN HEALTH.
