A processing method of flame retardant and fireproof calcium silicate board

Abstract

The present invention provides a method for processing a flame-retardant fireproof veneered calcium silicate board. A calcium silicate board and wood veneers are put into a hot press according to an order that a first layer of material and a third layer of material are wood veneers and a second layer of material is a calcium silicate board, and an adhesive mixture prepared by mixing unsaturated resin and cellulose cotton is used for seamlessly adhering a first-layer wood veneer and a third-layer wood veneer to two sides of the second-layer calcium silicate board separately by means of a curing hot-pressing treatment process. One hand, the calcium silicate board having two sides adhered with the wood veneers inherits excellent fire-retardant, fireproof, energy-saving and environmental-protection properties of the calcium silicate board, and on the other hand, the surface texture of the wood veneers increases beauty of the whole calcium silicate board; and the calcium silicate board is easy to sculpt, can be applied to furniture, floorboards, cabinets and other fields, has multiple functions of being waterproof, flame retardant, not easy to deform and easy moving, needs low manufacturing cost, and effectively prevents the defect that the formaldehyde content of traditional furniture exceeds a standard.

Description

technical field [0001] The invention relates to the field of building materials, in particular to a processing method for a flame-retardant and fire-resistant calcium silicate board. Background technique [0002] Calcium silicate board is made of organic and inorganic materials such as silicon, calcium materials and fibers through a series of production process molding, pressurization, high temperature, high pressure steaming and special technology. It has a long service life, safety and environmental protection, and is Widely used in interior and exterior walls of various buildings, suspended ceilings, road sound insulation (sound absorption) barriers, industrial panels and ceilings, pouring walls, panels of composite wall panels, interior and exterior insulation panels of exterior walls, inorganic pre-painted decorative panels , industrial fireproof insulation boards, etc., are ideal low-carbon energy-saving, green and environmentally friendly materials. And the calcium s...

Problems solved by technology

[0003] However, due to its own characteristics and appearance, traditional calcium silicate boards are often limited to the above-mentioned ceilings, partitions and other fields, and cannot replace the original density boards in furniture, floors, cabinets and other fields. Existing boards The furniture is made of density board and other materials, which have the disadvantages of not being able to withstand blisters, being flammable, not easy to move, and the probability of deformation is prominent, and it is difficult to control the formaldehyde exceeding the standard, which is harmful to human health. On the one hand, solid wood furniture is expensive, on the other hand, it Consumption of forest tree resources, affecting the ecological environment

[0004] If the calcium silicate board can be laminated with wood to make a material with aesthetics and fireproof and sound insulation functions, it will be an upgrade of the furniture industry if it is applied to the fields of furniture, floors, and cabinet lights. Two materials with different properties, thermal expansion and contraction are very different. It is difficult to permanently and seamlessly bond them together by ordinary methods, and it is easy to crack and separate when heated.
