Embodiment 1

[0032] The preparation method of a kind of formaldehyde-free flame-retardant high-strength woodworking board of the present embodiment comprises the following steps:

[0033] Step 1. Making woodworking core slats: select wood processing scraps, remove impurities and processing defects, add hydrogen peroxide for bleaching, send them into an ultraviolet sterilizer, fully sterilize, and make wooden strips with a width of 3 cm and a thickness of 5 cm;

[0034] Step 2. Soak the flame retardant: add the wood strips prepared in step 1 into the flame retardant solution, pressurize and soak for 10 minutes at a pressure of 2 atmospheres, and send the soaked wood strips into a dryer for drying;

[0035] Step 3, gluing and making boards; apply formaldehyde-free environmental protection adhesives on each surface of the wooden strips prepared in step 2, use a blockboard jigsaw to assemble the core strips into blockboard core board blanks, and then send them into the hot press machine The te...

Embodiment 2

[0045] The preparation method of a kind of formaldehyde-free flame-retardant high-strength woodworking board of the present embodiment comprises the following steps:

[0046] Step 1. Making woodworking core slats: select wood processing scraps, remove impurities and processing defects, add hydrogen peroxide to bleach, send them into an ultraviolet sterilizer, fully sterilize, and make wooden strips with a width of 7cm and a thickness of 9cm;

[0047] Step 2. Soak the flame retardant: add the wood strips prepared in step 1 into the flame retardant solution, pressurize and soak for 20 minutes at a pressure of 4 atmospheres, and send the soaked wood strips into a dryer for drying;

[0048] Step 3, gluing and making boards; apply formaldehyde-free environmental protection adhesive on each surface of the wooden strips prepared in step 2, use a blockboard machine to assemble the core strips into blockboard core board blanks, and then send them into the hot press machine The temperat...

Abstract

The invention discloses a production method of formaldehyde-free flame-retardant high-strength laminated wood boards. The method comprises the following steps: step one, manufacturing laminated wood board battens; step two, soaking the laminated wood board battens in fire retardant; step three, gluing and manufacturing boards; step four, producing face boards; and step five, assembling blanks to obtain the finished laminated wood boards. Through the method, various types of bonding glues are used; all the bonding glues are free of toxic and harmful materials such as formaldehyde and benzene compounds and the like; the material is subjected to flame-retardant treatment, so that the fire resistance and the high-temperature resistance of the laminated wood boards can be greatly improved; through hot pressing layer by layer, the close lamination is achieved; the mechanical strength of the material is greatly improved; meanwhile, a large quantity of wood wastes are adopted, so that the resources are saved; the cost is reduced; the production method has a high application value and a good application prospect.

Description

technical field [0001] The invention relates to the technical field of building decoration materials, in particular to a method for preparing a formaldehyde-free flame-retardant high-strength wood board. Background technique [0002] No matter in the past, now or for a long time in the future, blockboard will still be the main material for building interior decoration and furniture making. At present, the products sold on the market are mainly produced with urea-formaldehyde resin glue, and the blockboard produced by this will release formaldehyde which is harmful to the human body and the living environment. The country has mandatory standards for products sold, and their formaldehyde emission must meet the specified requirements. In order to meet the standard requirements, manufacturers use modified urea-formaldehyde resin adhesives for production, which greatly reduces the release of formaldehyde from blockboards, but this measure cannot completely eliminate the release ...
