Flame-retardant impregnated film adhesive facing blockboard

Abstract

The invention provides a flame-retardant impregnated film adhesive facing blockboard. The flame-retardant impregnated film adhesive facing blockboard comprises a board core, middle boards, poplar veneers, decorative film adhesive and flame-retardant adhesive layers, wherein the upper surface and the lower surface of the board core are correspondingly covered with the middle boards and are integrally pressed to form a board blank; adhesive connection is correspondingly carried out between the upper surface of the board core and the middle board as well as between the lower surface of the boardcore and the middle board through flame retardant adhesive layers, wherein the flame retardant glue layers are prepared by coating glue added with 25% of a urea glue flame retardant; the upper surfaceand the lower surface of the board blank are correspondingly covered with the poplar veneers and are integrally made into a base board through cold and hot pressing, and the upper surface of the board blank and the poplar veneer and the lower surface of the board blank and the poplar veneer are correspondingly subjected to adhesive connection through the flame retardant adhesive layers, wherein the flame retardant adhesive layers are prepared by coating glue added with the urea glue flame retardant in a proportion of 30%; and the decorative film adhesive is correspondingly pasted on the uppersurface and the lower surface of the base board, and finished products of the flame-retardant impregnated film adhesive facing blockboard are obtained through hot pressing and integral forming, so that the flame retardant performance of the impregnated film adhesive facing blockboard is improved, and meanwhile, environment protection is achieved, and various home decoration requirements of peoplecan be met.

Description

technical field [0001] The invention belongs to the field of plate processing, and relates to a blockboard with impregnated film and paper veneer, in particular to a flame-retardant blockboard with impregnated film and paper veneer. Background technique [0002] The occurrence of fire is often directly related to the use of combustibles that have not been treated with flame retardant. According to analysis, 21% of the fires are caused by fibrous materials such as wood, while 70% of residential fires are caused by the lack of flame retardancy of wood materials. With the continuous development of my country's economic construction and the improvement of people's living standards, people have put forward higher requirements for the aesthetics, comfort and other functions of architectural and decorative panels. Today's ordinary building and decoration boards are far from meeting the needs of the society. As a new type of environmentally friendly protective board, flame-retardan...
