Abstract

The present invention relates to a middle density fiberboard made of wheat straws or rice straws and a manufacture method thereof, and aldehyde adhesive is used as adhesive. Wheat straws and rice straws are used as main materials, and the present invention is manufactured by adding 8 to 12% of adhesive in the main materials. The manufacture processes are that after dust and earth are removed, wheat straws and rice straws are ground into crushed materials in a fiber bundle shape; SiO2 is separated; fine fibers are ground after a steaming and boiling procedure at high temperature; 8-12% of adhesive is added; the fine fibers in which adhesive is added are dried and paved for shaping; board blanks are prepressed and pressed in a heating mode, the edges are trimmed, the board surfaces are sanded, and thus, a middle density fiberboard made of wheat straws and rice straws is manufactured. The present invention enlarges the resource of middle density fiberboard raw materials, insufficient supply of a part of wood is solved and the cost is low.

Description

With straw straw medium density fibre board (MDF) and the manufacture method of aldehyde adhesive as adhesive
The invention belongs to a kind of medium density fiber board fabrication method, specifically is a kind of with the manufacture method of aldehyde adhesive as the straw straw medium density fibre board (MDF) of adhesive.
China's wood supply breach is very big at present, it is estimated to lack 6,000 ten thousand m in 2000 approximately 3Therefore utilize agricultural crop straw to make wood-based plate and have epochmaking meaning, it can be again to solve the important measures that straw burns as substitute for wood.(China also is) utilizes agricultural crop straw in the whole world, all focus on flax stalk, bagasse etc., studied with corn stalk again afterwards and made wood-based plate, particularly felt simply helpless with the making sheet of aldehyde adhesive stick and the agricultural thing of this class quantity maximum of straw straw is done waste material making sheet.Because the straw straw wheat face content of wax is very smooth, be commonly used to the aldehyde adhesive stick of veneer(ed) wood particieboard, can not well straw or straw be composed sheet material.The method of getting the raw materials ready commonly used now has the process of chopping, double drum wheel polishing method, hammers broken method into shape, and the product of the process of chopping is still the roundlet column, and what double drum wheel polishing method was produced is flakelet shape particle, and it is smooth still having one side.With the broken method production of hammer is needle-like or sheet particle, equally also still has one-sided smooth, and this is that the aldehyde adhesive stick can not glue together good major reason.And it is more much higher with other class glue than aldehyde adhesive cost.
The purpose of this invention is to provide a kind of is medium density fibre board (MDF) and the manufacture method that raw material is made with the straw straw, and this method is that the straw straw is made fiber, adopts aldehyde adhesive as adhesive, has reduced the cost of plate.
The present invention is to be primary raw material with straw straw and aldehyde adhesive stick, and the adhesive consumption is 8%～12% of a straw straw amount.
The technical scheme of manufacture method of the present invention is finished by following operation successively:
1. raw material straw straw is removed dust;
2. clean straw straw is broken into particle;
3. separate the dust in the particle;
4. will carry out thermophilic digestion through the raw material of above-mentioned processing, boiling temperature be 110 ℃～
170℃；
5. the particle of boiling is worn into fiber;
Toward grind fiber in apply aldehyde adhesive, resin added is 8%～12%;
7. sized fiber is carried out drying, 200 ℃～350 ℃ of baking temperatures are done
Dry time 5～10s;
8. the moulding of mating formation;
9. slab precompressed;
10. slab hot pressing, 130 ℃～170 ℃ of hot pressing temperatures, pressure 2.5MPa～
5.5MPa the time is 30～50s/mm thickness of slab;
11. with the straw straw medium density fibre board (MDF) hair plates cutting edge after the hot pressing;
12. plate facing sand light.
By the straw straw medium density fibre board (MDF) that said method is produced, the quality of plate can be contrasted with " medium density fibre board (MDF) " standard GB-11718-89.The performance of medium density fibre board (MDF) of producing and the medium density fibre board (MDF) made with timber is very approximate.
The present invention has enlarged the source of medium density fiber board raw material, and most that makes the nearly 200,000,000 tons of straw straw of annual output can substitute timber, solves the breach of a part of wood supply deficiency, can no longer burn straw again, reduces air environmental pollution.Make straw straw medium density fibre board (MDF) by this production method, can use the aldehyde adhesive stick, thereby reduce the cost of plate greatly.
Embodiment:
Get 1 ton of straw (or straw) raw material, soil is removed in dedusting, puts into Hammermill hammer and wears into particle, and this particle is separated meticulous dust in seperator.Particle high-temperature steam boiling, boiling temperature is 150 ℃, the particle of boiling is put into Cold grinder or defibrator or is used thermomechanometry, grind into fiber, impose the aldehyde adhesive stick in fiber, resin added is 12%, sized raw material is by the drying machine drying, baking temperature is 250 ℃, after time 10s, dried applying glue raw material put into the spreading machine upper berth and dress up type, put into the precompressed of preformer slab, preload pressure 1.5Mpa, the hot press hot pressing of the slab after the precompressed, 160 ℃ of hot pressing temperatures, pressure 3.5MPa, time 30s/mm thickness of slab, the hair plates cutting edge after the hot pressing is the about 1m of straw straw medium density fibre board (MDF) of adhesive with promptly making with the aldehyde adhesive behind the abrasive finishing machine abrasive finishing plate face 3
