Problems solved by technology

Although the flame-retardant blockboards produced by some factories have certain flame-retardant properties, because the blockboard core boards and glued boards have not undergone special technical treatment during the production process, the moisture content of adjacent wood strips inside the blockboard core boards is different. Even and a certain residual stress, affected by changes in ambient temperature and humidity during use, the wood strips of the core board are inconsistent with deformation and moisture expansion, which will be displayed on the surface of the blockboard, causing uneven wood blocks on the board surface Imprinting, which seriously affects the decoration quality
Therefore, ordinary flame-retardant blockboard can only be used as low-grade furniture and decoration materials.

Embodiment Construction

[0033] Below in conjunction with accompanying drawing, the present invention will be further described:

[0034] combine Figure 1-Figure 2 , the present embodiment provides a method for making a composite flame-retardant blockboard, which is realized by the following specific steps:

[0035] 1. The preparation method of flame retardant water solvent: the ALFR type flame retardant selected as the flame retardant is a non-halogen water-based environmentally friendly flame retardant that does not contain formaldehyde and has strong flame retardant performance, easy penetration, and Loss, smoke suppression and anti-mildew effects, its main ingredients are hydroxymethyl phosphate amidinourea and boric acid, the appearance is white powdery substance, molecular formula: OHCH2HNC(NH2)NHCONH2·H2PO4+H3BO3. When preparing, add the flame retardant into warm water at about 50 degrees at a ratio of 15:85, and stir well to dissolve the flame retardant into a transparent solution.

Abstract

The invention relates to a preparation method for composite inflaming retarding core-board. The technology of filling a flame retardant by secondary vacuumizing / pressurizing is employed to lead the flame retardant to be more sufficiently dipped into the inside of a core-board strip and improve the inflaming retarding performance of the core-board strip. The flame retardant employs a non-halogen water-base environmental-friendly compound flame retardant which does not contain formaldehyde, has strong inflaming retarding performance, smoke inhibiting and mould-proof effects. The invention is a manufacture method for employing the low-grade wood or leftover materials after processing like undersized logs and removing the quality and processing defects to produce high-grade composite inflaming retarding core-board. The product of the invention has the characteristics of inflaming retarding, corrosion resistance, environment protection, heat preservation, sound isolation, and easy processing, and is an ideal fire-proof inflaming retarding material for the industries like furniture, door manufacture, and building decoration.

Description

(1) Technical field [0001] The invention relates to the technical field of blockboard preparation, in particular to a method for producing high-grade composite flame-retardant blockboard by using low-grade wood such as small-diameter wood or processing leftovers. (2) Background technology [0002] Blockboard is widely used in furniture, interior decoration and decorative construction industries, etc., but due to the flammability of blockboard, there is a great fire hazard. The occurrence of fire is often caused by the lack of fire resistance of wooden materials. Although the flame-retardant blockboards produced by some factories have certain flame-retardant properties, because the blockboard core boards and glued boards have not undergone special technical treatment during the production process, the moisture content of adjacent wood strips inside the blockboard core boards is different. Even and a certain residual stress, affected by changes in ambient temperature and humi...
