Abstract

The invention relates to the field of plates, and specifically relates to a plate containing a modified urea formaldehyde foam adhesive, as well as application and a preparation method thereof. The plate containing the modified urea formaldehyde foam adhesive is prepared from the following raw materials: the modified urea formaldehyde foam adhesive and a powdery inorganic material carrier, wherein the inorganic material carrier comprises any one of perlite, vermiculite, gypsum, wollastonite, kieselguhr and cinerite; the modified urea formaldehyde foam adhesive is prepared from the following raw materials in parts by weight: 500-700 parts of formaldehyde, 200-350 parts of urea, 10-20 parts of melamine and 2-4.5 parts of hexamine. Compared with the prior art, the plate containing the modified urea formaldehyde foam adhesive has the advantages that the content of formaldehyde in the foam adhesive is reduced and carcinogenic harm and environmental pollution are avoided.

Description

technical field [0001] The invention relates to the field of boards, in particular to boards containing modified urea-formaldehyde foam glue, applications of boards and preparation methods thereof. Background technique [0002] In the application fields of construction, board, core material, insulation, etc., board is widely used, and the main application of board is urea-formaldehyde glue and glass and rock powder. [0003] Urea-formaldehyde glue is the polycondensation of urea and formaldehyde under the action of catalyst (basic catalyst or acid catalyst) to form initial urea-formaldehyde resin, and then under the action of curing agent or auxiliary agent, it forms an infusible and insoluble final resin adhesive. Since urea-formaldehyde glue contains a lot of formaldehyde inside, and formaldehyde is a carcinogen, and the abnormal smell is relatively large, and there are few types of glass and rock powder, which seriously restricts the application space of the board. Cont...
