Problems solved by technology

For example: plates made of metal, plates treated with flame-retardant wood, or a combination of the above two forms; the above-mentioned forms do have good flame-retardant effects when metal materials are involved, because metal is inconvenient to cut and the price is too high. The defects of high post-processing difficulty and high cost; based on the above reasons, the flame-retardant treated board is the main type of board used in the flame-retardant market, but this type of board is only slow in the combustion process and still produces a lot of heat and smoke. When burning It cannot play a real barrier role; in addition, this type of flame-retardant board generally has the problems of low density, easy deformation, poor hardness, and easy warping, which makes it unable to be used as high-end furniture.

preparation example Construction

[0049] The present invention also provides a method for preparing a flame-retardant polymer composite plate, comprising the following steps:

[0050] Step 1: Put the fiber organic powder, mineral powder and binder in a container for stirring, and wait until the above materials are evenly mixed for later use;

[0051] Step 2: Put the uniformly mixed material into a mold that can withstand heavy pressure for a long time, and press the uniformly mixed material through a press to become a semi-finished organic-inorganic polymer composite core layer; the pressure of the press is : 1000~1500t, pressing time: 16~24h;

[0052] The thickness of the semi-finished organic-inorganic polymer composite core layer is the same as the thickness of the organic-inorganic polymer composite core layer (2);

[0053] Step 3: Make the organic-inorganic polymer composite core layer semi-finished product go through shaping, drying, sanding, cutting, inspection, finished product, and packaging processe...

Abstract

The invention belongs to a flame-retardant polymer composite board and a preparation method thereof. The composite board comprises an upper-layer flame-retardant board unit, an organic-inorganic polymer composite core layer and a lower-layer flame-retardant board unit, a first bonding layer is arranged between the upper-layer flame-retardant board unit and the organic-inorganic polymer composite core layer, and a second bonding layer is arranged between the organic-inorganic polymer composite core layer and the lower-layer flame-retardant board unit; and the composite board has the advantages of being simple in structure, reasonable in design, large in density, free of deformation, good in hardness, free of warping, capable of effectively prolonging combustion time and reducing spreading speed when a fire disaster occurs, especially capable of effectively blocking combustion through the organic-inorganic polymer composite core layer, and suitable for buildings, engineering, decoration, home decoration, door frames and high-grade furniture.

Description

technical field [0001] The invention belongs to the field of flame-retardant plates, and in particular relates to a flame-retardant polymer composite plate and a preparation method. Background technique [0002] In modern offices and homes, many materials are flammable. Due to the uncertainty of fire, when a fire breaks out, the boards used for decoration and furniture are burned, on the one hand, it will generate a lot of heat, on the other hand, it will emit toxic gas and smoke, which increases the danger of fire. In order to solve the above technical problems, many board manufacturers have developed flame-retardant boards of different materials. For example: plates made of metal, plates treated with flame-retardant wood, or a combination of the above two forms; the above-mentioned forms do have good flame-retardant effects when metal materials are involved, because metal is inconvenient to cut and the price is too high. The defects of high post-processing difficulty and...
