Abstract

The utility model relates to a chipboard for strengthening physical and mechanical properties. The chipboard is designed for raising the bending resistance and the tensile strength of the chipboard. The utility model is characterized in that reinforcing ribs are arranged in the chipboard; the reinforcing ribs are bonded and pressed together by shavings, saw dusts, coarse fiber adhesive, etc. thereby, the mechanical properties of the chipboard are improved, the bending resistance and the tensile strength of the chipboard are raised, and the utility model satisfies using requirements.

Description

The reinforcement particieboard

Technical field

The utility model relates to a kind of furniture, finishing, packaging material, specifically a kind of reinforcement particieboard.

Background technology

Its structure of particieboard of producing is pressed into tabular mixture by material adhesives such as wood shavings, sawdust, crude fibre and adhesives now.Because raw-material fiber is short in the particieboard, adhesive solidifies the back embrittlement, causes particieboard bending resistance, tensile strength low, fractures easily, does not satisfy the production instructions for use.

The utility model content

The purpose of this utility model is exactly the reinforcement particieboard of a kind of new construction of design, to improve its bending resistance, tensile strength, satisfies the needs that packing is produced and used.

The utility model is achieved in that in by wood shavings, sawdust, crude fibre, the bonding mixture that is pressed into of adhesive and is provided with reinforcement.Inside at particieboard increases reinforcement, can improve the mechanical performance of particieboard.More popular saying, just as bending resistance, the tension mechanical performance that reinforcing bar can improve prefabricated board being set in building panel (floor) inside, in the particieboard production process, reinforcement is placed on the inside, repressed drying, reinforcement and raw material such as wood shavings, sawdust are bonded together, form a monoblock reinforcement particieboard.The reinforcement number of plies divide one deck, two layers or multilayer, decide according to purposes.The material of reinforcement can adopt the plant straw, as bamboo bar, batten, the twigs of the chaste tree, branch bar, reed, reed, rattan, cotton straw etc., also can utilize other materials such as non-plant wire rod, plastics, steel wire.The cross section structure of reinforcement also can be diversified, as circle, side, polygonal or various formed steel construction.

Description of drawings

Fig. 1 is the cross section structure schematic diagram that the utility model has one deck reinforcement.

Fig. 2 is the cross section structure schematic diagram that the utility model has two layers of reinforcement.

Fig. 3 is the cross section structure schematic diagram that the utility model has the multilayer reinforcement.

Fig. 4 is that the utility model is the cross section structure schematic diagram of netted reinforcement.

The specific embodiment

As shown in Figure 1, the utility model is reinforcement 2 to be cooperated with auxiliary material 3 be woven together, and forms nettedly, is placed in the mixture 1 that is formed by composite materials such as wood shavings, sawdust, crude fibre, adhesives, is pressed into the reinforcement particieboard.Reinforcement 2 be placed in the mixture 1 by under the position, to bear the suffered pulling force of particieboard preferably.

As shown in Figure 2, reinforcement 2 and auxiliary material 3 are placed on the upper and lower position of material mixture 1, divide two layers, and during use, one deck muscle is subjected to pulling force, and another layer muscle is stressed, thereby the bending resistance of reinforcement particieboard, tensile strength height, and serviceability is better.

As shown in Figure 3, as required, placement of multiple layers reinforcement 2 and auxiliary material 3 in the material mixture 1 make made reinforcement particieboard intensity higher.

As shown in Figure 4, reinforcement 2 and auxiliary material 3 materials are basic identical, are woven into nettedly, are placed in the mixture 1 of materials such as wood shavings, sawdust, crude fibre, adhesive press forming.Vertical, horizontal bending resistance, the tensile strength of reinforcement particieboard are all good like this.

In the utility model, reinforcement 2 can one one single the putting in ground, and it is netted also can to cooperate auxiliary material 3 that reinforcement 2 is woven into, and integral body is placed in the mixture 1.Can improve make efficiency of the present utility model like this, also increase the intensity of particieboard simultaneously.

In the utility model, reinforcement can vertically be placed, laterally place, and also can horizontal, vertically be staggeredly placed.

Claims

1, a kind of reinforcement particieboard by the bonding mixture (1) that is pressed into of wood shavings, sawdust, crude fibre and adhesive, is characterized in that being provided with reinforcement (2) in mixture (1).

2,, it is characterized in that reinforcement (2) is one or more layers according to claims 1 described reinforcement particieboard.

3,, it is characterized in that reinforcement (2) can singlely put or cooperate auxiliary material (3) to be woven into netted according to claims 1 or 2 described reinforcement particieboards.
