Abstract

The invention relates to a technology in the field of composite materials, and discloses a method for producing laminated wood boards by using waste and used plywood cement templates. The method comprises the following steps of: sawing the waste and used plywood cement templates into battens with certain length, width and thickness to serve as the core strips of the laminated wood boards; carrying out lateral cement pressing on the core strips to prepare the board cores of the laminated wood boards; and sticking a veneer and thin wood on two surfaces of each boardcore to prepare the laminated wood boards. The method has the technical characteristics that the core strips which can be manufactured to have certain length, width and thickness in the waste and used plywood cement templates are used for producing the laminated wood boards.

Description

Waste and old glued board cement formwork is produced the new technology of composite wooden material

One, technical field

The invention discloses a kind of method of utilizing waste and old glued board cement formwork to produce core-board.With waste and old glued board cement formwork cut off to length, the lath of width and thickness, as the central layer bar of core-board, its technical characteristics is: utilize the mid portion of waste and old glued board cement formwork to produce core-board.

Two, background technology

Along with the development of national economy, increasing to the demand of timber, but the scarcity of timber resources forces people to utilize various raw materials to research and produce composite wooden material, the deficiency of the needs of satisfying the market and alleviation timber resources.Utilizing each waste and old wood to produce composite is domestic and international outline and research forward position.

Glued board cement formwork construction technology is applied one of new technology as ten of the Ministry of Construction, and its use amount is increasing.Construction practices for many years shows, the glued board cement formwork has the advantages such as reduce labor strength, constructability, be easy to combination, cost is lower, develop the increase that speeds with foreign trade with domestic economy, construction scope increases rapidly, the construction of domestic skyscraper, the demand of the template of building industry is in rising trend, and that the glued board cement formwork has a breadth is large, from heavy and light, the turnover access times are many, be particularly suitable for making large section mould plate, construction quality and efficiency of construction increase substantially, and have promoted the production development of plywood form.Along with the consumption increase of glued board cement formwork, the quantity of waste and old glued board cement formwork also sharply increases, and how to utilize these waste and old glued board cement formworks to make it to turn waste into wealth, and environmental contamination reduction is current, and even research direction from now on.

To can make the batten of certain thickness and width in waste and old glued board cement formwork as making the core-board material.Not only can take full advantage of waste and old wood and environmental contamination reduction, and there is structural inconsistency in the timber resources that can alleviate China.

Three, summary of the invention

1. the purpose of inventing

The object of the invention is to enlarge utilizing scope and improving use value of waste and old glued board cement formwork.Waste and old wood recycling is conducive to protect China's wildwood resource and protected ecological environment and the ecological balance.Utilize the product of urea-formaldehyde resin adhesive production high added value scrap rubber plywood cement formwork.

2. technical scheme

1) waste and old glued board cement formwork is made joiner's preparation method, it is characterized in that its manufacturing technology steps is divided:

1. with waste and old glued board cement formwork, being sawn into width is the 15-30mm strip material, amputates or the breakable layer on thickness direction two surfaces of shooting off, and strip material is sawed-off, and its length is not less than 300mm, as the core bar of core-board;

2. the core bar is through the side gluing, and the plate core that it is 8-20mm that assembly becomes the long 2440mm thickness of wide 1220mm is then through side pressurization manufactured Board core, side moulding pressure 0.3-0.5MPa, temperature 110-140 ℃.Core bar extensible during plate core assembly, during spreading, joint will suitably stagger at width and the length direction of plate core, does not occur a plurality of joints in a partial splice zone;

3. respectively paste one through single spreading on the both sides of plate core, thickness is the rotary cut venner of 1.2-2.5mm, makes blank flat through hot pressing; The glue-spread of veneer is 200-350g/m 2, hot pressing temperature is 100-120 ℃, hot pressing pressure 0.6-1.0MPa, hot pressing time 1.5-4min;

4. blank flat is through repairing and sanding, then carries out the hot pressing veneer of panel, backboard, and hot pressing temperature is 100-140 ℃, and hot pressing time 30-90s makes core-board.

Four, the specific embodiment
