Problems solved by technology

[0003] The purpose of the present invention is to provide a kind of flame retardant and waterproof decorative board for the current situation that the existing decorative artificial boards have serious flammability problems and are not suitable for use in environments with high temperature and humidity or large changes in temperature and humidity. Method: In the production process of the decorative board, the non-aldehyde adhesive is evenly coated on the surface of the flame-retardant inorganic glass magnesium board, and then it is combined with veneer and honeycomb aluminum foil to form a blank, and finally it is cold-pressed and shaped. Heat-curing treatment to produce decorative panels with the decorative effect of natural wood, good flame retardant and waterproof effects, as well as thermal insulation and sound insulation functions

Embodiment 1

[0023] (1) Veneer processing: use a planer to process the wood into thin wood with a thickness of 0.5 mm;

[0024] (2) Drying of veneer: use mesh belt drying method to dry the moisture content of veneer to 12%;

[0025] (3) Glue coating: use a four-roll double-sided glue coating machine to evenly coat the adhesive (mainly composed of polyvinyl alcohol, magnesium oxide, magnesium chloride, industrial flour, water and surfactants) on the upper and lower sides of the glass magnesium board. (4) Aging: aging the glued glass magnesium board for 1.0 hour to evaporate the excess water in the adhesive;

[0026] (5) Blank assembly: Composite assembly of the aged glue-coated glass magnesium board, veneer, and honeycomb aluminum foil with upper and lower surfaces; the slab has a five-layer structure, in which the honeycomb aluminum foil is located in the middle of the slab, and the two sides of the honeycomb aluminum foil Each has a glass magnesium board, and two layers of veneer are res...

Embodiment 2

[0031] (1) Veneer processing: using string cutting machine to process logs into veneer with a thickness of 1.0mm;

[0032] (2) Drying of veneer: Dry the moisture content of veneer to 10% by flat-plate hot pressing drying method;

[0033] (3) Glue coating: use a four-roll double-sided glue coating machine to evenly coat the adhesive (mainly composed of polyvinyl alcohol, magnesium oxide, magnesium chloride, industrial flour, water and surfactants) on the upper and lower sides of the glass magnesium board. surface, the amount of double-sided glue is 600 grams per square meter;

[0034] (4) Aging: aging the glued glass magnesium board for 1.5 hours to evaporate the excess water in the adhesive;

[0035] (5) Blank assembly: Composite assembly of aged glue-coated glass magnesium board, veneer, and honeycomb aluminum foil with upper and lower surfaces. The slab has a 5-layer structure, in which the honeycomb aluminum foil is located in the middle of the slab, and there is a glass ...

Abstract

A method for producing a flame-retardant waterproof decorating plate is that: during the production process of the decorating plate, the non-aldehyde adhesive is uniformly coated on the surface of a flame-retardant inorganic glass magnesium plate, then, the flame-retardant inorganic glass magnesium plate, a veneer and a honeycomb aluminum foil are in composite assembling, and finally, through cold-pressed forming and thermocuring treatment, the decorating plate which has not only a natural wooden decorating effect but also good flame-retardant and waterproof effects as well as the functions of thermal insulation and sound insulation is produced. The decorating plate which is produced by the technology has the fire resistance rating which reaches the fire-retardant level, can be used in the humidity environment for a long time, and has good thermal insulation and sound insulation effects, and the release amount of free formaldehyde of the plate reaches the E0 level.

Description

technical field [0001] The invention belongs to the field of wood-based panel manufacturing in the wood industry, in particular to a method for manufacturing a flame-retardant and waterproof decorative panel. Background technique [0002] As a renewable and recyclable environmentally friendly ecological material, wood is widely used in furniture, flooring, building decoration and other industries due to its natural color and beautiful patterns. In recent years, with the strengthening of my country's economy and the improvement of people's living standards, the consumption of wood has been increasing year by year. By 2007, it has exceeded 150 million cubic meters, and the use in construction and interior decoration alone has exceeded 80 million cubic meters per year. However, there is a serious flammability problem in wood, and the occurrence and spread of fires in many buildings are directly related to wood. Fires caused by wood are still a major problem that endangers the s...
