The surface of the fiberboard is smooth and easy to paste various finishes, which can make the furniture and interior decoration more beautiful. materials are widely used. Because urea-formaldehyde resin is mainly used as the adhesive for fiberboard production in dry-process fiberboard production, there are common problems such as formaldehyde pollution, and fiberboard is generally used as a common board. With the adjustment of my country's forestry industry policy, the construction of a national timber strategic resource reserve base, the main cutting of natural forests in the Daxingan Mountains and Changbai Mountains will be completely stopped in 2015. Under this background, small-diameter wood and forest logging residues are used as the main raw materials. The production of fibreboard from the source brings about the problem of raw material supply.

本发明硅藻土导电材料复合抗静电环保农林剩余物纤维板制造原料易得，为市售产品。The diatomite conductive material composite antistatic environmental protection agricultural and forestry residue fiberboard of the present invention has easy-to-obtain raw materials and is a commercially available product.
本发明所述的硅藻土是硅藻土原土及煅烧硅藻土，硅藻土是海洋或湖泊中生长的硅藻类的残骸在水底沉积经过地质作用而逐渐形成的一种天然多孔矿物材料，一般为1～100μm，硅藻壳体具有特殊的孔结构及由非晶质二氧化硅构成的壳壁及分布于壁上的小孔，能吸附或负载其他化学组分，可制备良好的载体或吸附材料。The diatomaceous earth described in the present invention is diatomite raw earth and calcined diatomite. Diatomite is a kind of natural porous mineral material that is gradually formed by the remains of diatoms growing in oceans or lakes and deposited on the bottom of the water through geological processes. , generally 1 to 100 μm, the diatom shell has a special pore structure and a shell wall composed of amorphous silica and small pores distributed on the wall, which can adsorb or load other chemical components, and can be used to prepare good carrier or adsorbent.
本发明所述的导电材料是导电炭黑、导电石墨、导电纤维、导电胶黏剂等，导电材料事先加入到胶黏剂中，与胶黏剂一起加入到纤维中。The conductive material in the present invention is conductive carbon black, conductive graphite, conductive fiber, conductive adhesive, etc. The conductive material is added to the adhesive in advance, and added to the fiber together with the adhesive.
本发明所述的胶黏剂为纤维板用低游离甲醛脲醛树脂。The adhesive described in the present invention is low free formaldehyde urea-formaldehyde resin for fiberboard.
本发明所述防水剂为熔点在52～58℃的工业石蜡，经熔化后与胶黏剂一起加入到纤维中。The waterproofing agent in the present invention is industrial paraffin wax with a melting point of 52-58°C, which is added to the fiber together with the adhesive after melting.
本发明主要利用硅藻土的吸附性吸附纤维板制品中胶黏剂中的游离甲醛及胶黏剂在使用过程中因老化分解而释放出的甲醛，进而降低纤维板的甲醛释放量，使纤维板的甲醛释放量始终满足E0级环保要求；同时利用导电材料的导电特性，将粉末状或纤维状的导电材料与胶黏剂混合均匀后加入到纤维中，使之均匀的分布于纤维表面，在压制成的纤维板内部形成导电网格，可使纤维板的系统电阻值降低至1×109以下，达到抗静电木质地板对系统电阻的要求；采用二级干燥工艺，纤维在完成一级干燥的同时，因一级干燥的高温干燥工艺，使胶黏剂中的大部分游离甲醛随水分一起排出，在二级干燥前在加入硅藻土可有效避免硅藻土吸附大量游离甲醛而导致其后续吸附作用的降低，最大限度的发挥硅藻土的作用。The present invention mainly utilizes the adsorption of diatomite to absorb the free formaldehyde in the adhesive in the fiberboard product and the formaldehyde released by the adhesive during use due to aging and decomposition, thereby reducing the formaldehyde emission of the fiberboard and making the formaldehyde of the fiberboard The amount of release always meets the environmental protection requirements of E 0 level; at the same time, using the conductive properties of conductive materials, the powdery or fibrous conductive materials and adhesives are evenly mixed and added to the fibers so that they are evenly distributed on the surface of the fibers. The conductive grid is formed inside the fiberboard, which can reduce the system resistance value of the fiberboard to less than 1×10 9 , which meets the requirements of antistatic wood flooring for the system resistance; the second-level drying process is adopted, and the fibers are dried at the same time as the first-level drying. Due to the high-temperature drying process of the first-stage drying, most of the free formaldehyde in the adhesive is discharged together with the water. Adding diatomite before the second-stage drying can effectively prevent the subsequent adsorption of diatomite from absorbing a large amount of free formaldehyde. The reduction, to maximize the role of diatomaceous earth.
