Description

A kind of wood wool enhancing rice straw plate

Technical field

The utility model belongs to technical field of artificial boards, and in particular to a kind of wood wool enhancing rice straw plate.

Background technique

It is more and more in short supply for the forest timber resource of felling with the implementation of China's natural forest protection policy, but with Building decoration and furniture consumption demand are growing day by day, and domestic lumber consumption increases rapidly.At the same time, China generates largely every year Crops rice straw, these rice straw some are by on-site incineration, and some is out of office outer by stack retting, these unreasonable stalks Processing mode not only wastes biomass resource, and serious pollution of ecological environment.It is manufactured by primary raw material of agricultural crop straw Artificial board develops crops rice straw plate industry, is to alleviate the contradictory effective way of timber supply and demand, is to realize " stalk generation The environment-friendly type new industry of wood " is also beneficial to build beautiful rural area and preserve the ecological environment.

Rice straw plate the advantages such as saves timber resources and preserves the ecological environment due to having, and industrialization is also by people Attention.But rice straw plate primary raw material is rice straw, and rice straw has source dispersion, collection difficulty big, seasonal The features such as strong, causes the supply of raw material to exist and is difficult to meet large-scale industrial production, and the hardened structure of rice straw is unstable It is fixed, it is easily deformed, it is difficult to be applied to furniture building materials field on a large scale.

Utility model content

The purpose of this utility model is to provide the wood wools of a kind of stable structure, lighting to enhance rice straw plate.

This wood wool provided by the utility model enhances rice straw plate, including set gradually from top to bottom surface layer, core Layer and bottom, the surface layer, bottom are rice straw layer, and structure of putting together is laminated by the wood wool rice straw of multilayer in the sandwich layer At the wood wool rice straw layer is made of wood wool and rice straw, the wood wool oriented alignment in wood wool rice straw layer, every phase Wood wool in adjacent wood wool rice straw layer is mutually perpendicular to, and the rice straw in wood wool rice straw layer is set to the gap of wood wool In, to play filling effect.

Preferably, enhance rice straw plate thickness with a thickness of wood wool 1/2~3/4 of the sandwich layer.

Preferably, the surface layer, rice straw length≤3mm in bottom.

Preferably, the rice straw length in the sandwich layer is 15~35mm.

Preferably, the length of the wood wool is 50~120mm, and width is 0.5~3mm, with a thickness of 0.45~2mm, wood wool It is prepared using broad-leaved wood or needle timber.

Preferably, the weight ratio of wood wool and rice straw is 1:(0.2~0.6 in the wood wool rice straw layer).

Preferably, the sandwich layer is made of three layers of wood wool rice straw layer.

This wood wool provided by the utility model enhances rice straw plate, constructs three layers of orientation of wood wool and rice straw Sandwich layer of the space structure as stalk board makes wood wool play the role of skeletal support in plate, and forms one kind with rice straw The structure of dimensionally stable is conducive to save material, reduces transportation cost, reduces the density of rice straw plate, is conducive to subtract The consumption of few raw material, realizes the lighting of rice straw plate.

Detailed description of the invention

Fig. 1 provides a kind of cross-sectional view of wood wool enhancing rice straw plate for the utility model.

Fig. 2 provides a kind of wood wool enhancing rice straw plate plate blank paving structural schematic diagram for the utility model.

In figure: 1-surface layer；2-sandwich layers；3-bottoms.

Specific embodiment

The utility model is described in detail With reference to embodiment.

This kind of wood wool provided by the utility model enhances rice straw plate, as shown in Figure 1, including from top to bottom successively Surface layer 1, sandwich layer 2 and the bottom 3 of setting, surface layer 1, bottom 3 are rice straw layer, and sandwich layer 2 is laminated by three layers of wood wool rice straw It puts together composition, wood wool rice straw layer is made of wood wool and rice straw, and the wood wool in wood wool rice straw layer orients row Cloth, often the wood wool in adjacent wood wool rice straw layer is mutually perpendicular to, and the rice straw in wood wool rice straw layer is set to wood In the gap of silk, to play filling effect.

In the present embodiment, enhance rice straw plate thickness with a thickness of wood wool 2/3 of sandwich layer；Rice in surface layer, bottom Careless stalk length≤3mm；Rice straw length in sandwich layer is 15~35mm；The length of wood wool is 50~120mm, and width is 0.5~3mm, with a thickness of 0.45~2mm, wood wool is prepared using broad-leaved wood；Wood wool and straw in wood wool rice straw layer The weight ratio of stalk is 1:0.4.

The preparation step that the present embodiment wood wool enhances rice straw plate is as follows:

(1) it using rice straw as raw material, after rice straw is by crushing, is sieved by the sieve in the aperture 3mm, obtains rice Careless fines is glued straw fines, is glued using the glue system that high pressure homogeneous pump and atomization jetting device form, For isocyanates as adhesive, resin added is the 3~6% of raw material weight, by pipeline drying machine that raw material moisture is dry after sizing To 6~10%, then it is delivered to leading portion and back segment feed bin, mated formation raw material as surface layer and bottom；

(2) using broad-leaved wood as raw material, logs of wood is obtained after rotary-cut is processed and is dried with a thickness of 0.45~2mm Wooden veneer, Wooden veneer is subjected to chopping and truncation, is processed into that length is 50~120mm, width is 0.5~3mm, thickness It is spare for the wood wool of 0.45~2mm；

(3) using rice straw as raw material, straw obtains length after cutting as the rice straw of 15~35mm, then with The wood wool that step (2) obtains uniformly is mixed in drum-type glue mixer, is glued, is adopted to wood wool and rice straw mixture It is glued with the glue system that high pressure homogeneous pump and atomization jetting device form, isocyanates is as adhesive, resin added The 3~6% of raw material weight, it is by pipeline drying machine that raw material moisture is dry to 6~10% after sizing, it is delivered to middle section feed bin, is made Mat formation raw material for sandwich layer；

(4) five spreading head spreading machines are used, as shown in Fig. 2, the raw material of mating formation of bottom obtained by step (1) is passed through leading portion Fibre spread head is layered on bottom, and the raw material of mating formation of sandwich layer obtained by step (3) is mutually hung down according to three layers using three orienting spreading heads Straight structure is layered on sandwich layer, so that wood wool is presented three layers in the core is mutually perpendicular to structure, rice straw is in wood wool three-decker It plays filling effect, then the raw material of mating formation of surface layer obtained by step (1) is mated formation on surface layer by back segment fibre spread head, finally by company Continuous precompressed, hot pressing obtain wood wool enhancing rice straw plate.

In conclusion the utility model constructs three layers of directional space structure of wood wool and rice straw as stalk board Sandwich layer makes wood wool play the role of skeletal support in plate, and a kind of structure of dimensionally stable is formed with rice straw, reduces The density of rice straw plate advantageously reduces the consumption of raw material, realizes the lighting of rice straw plate.
