Description
Technical Field
The invention relates to the technical field of artificial board manufacturing, in particular to a PB board odor control process.
Background
The PB board is an artificial board, called shaving board, particle board, bagasse board, etc., which is made by cutting the main raw material into pieces of a certain specification, drying, mixing with sizing material, hardening agent, waterproofing agent, etc., and pressing under a certain temperature and pressure. The PB plate is mainly used for furniture and building industry, train and automobile carriage manufacturing and the like.
The chinese PB plate production went through a repetitive process of 20 th century rising from 80 s, to 90 s declining and then to 2000 s rising again. The quality of the PB board is obviously improved and accepted by the market again after the PB board is abandoned by the market due to poor quality and other reasons, many PB board enterprises absorb teaching and training, after foreign advanced production lines are introduced and the process level is improved, many furniture manufacturing enterprises select the PB board as the raw material again, and furthermore, the oriented PB board is accepted by consumers gradually, so that the demand of the Chinese PB board is increased year by year in recent years. With the increasing demand of PB boards at home and abroad and the promotion of preferential policies of China, the development of the artificial board industry is encouraged, and excellent conditions are created for the development of the PB board industry.
In recent years, with the increasing living standard and the increasing awareness of environmental protection, more and more consumers are concerned about the smell of the customized furniture products, mainly the smell of the artificial boards for the customized furniture. The wood raw materials, chemical raw materials, production process, cooling and curing treatment and the like used by the PB plate are main factors influencing the smell of the PB plate. In the prior art, the odor of the PB board is mostly controlled by adopting a veneering treatment mode, but the veneering PB board produced by a common factory at present is limited by the production process level, and the veneering treatment of the PB board cannot play a role in sealing certain hazardous substances in a flakeboard, so that a large amount of aromatic compounds contained in the flakeboard is released. Based on the above statement, the invention provides a PB plate odor control process.
Disclosure of Invention
The invention aims to solve the problem that in the prior art, the odor of a PB board is controlled by adopting a veneering treatment mode, and the veneering treatment cannot play a role in sealing harmful substances in a particle board element board, so that a large amount of aromatic compounds contained in the particle board element board are released, and provides a PB board odor control process.
A PB plate odor control process comprises the following steps:
s1: preparation of plain plate
S11, adding corn straws and Chinese fir wood into the cooking liquor together for cooking treatment, after primary deodorization, washing with water, and drying until the water content is 18-28% to obtain a mixed raw material;
s12, conveying the dried mixed raw materials into a wood shaving machine for wood shaving, drying the obtained wood shaving, uniformly mixing the obtained wood shaving with an adhesive, paving, and carrying out hot pressing to obtain a plain board;
s2: preparing composite veneers
Adding polycarbonate and corn straw fiber into a mixer together, uniformly mixing, adding p-toluenesulfonylacetone hydrazone and ethylene glycol dimethacrylate, carrying out micro-foaming at the temperature of 40-70 ℃ until the foaming ratio is 5-8 times, and carrying out extrusion molding to obtain a composite veneer;
s3: preparation of veneered PB Panel
S31, connecting the composite veneers, the plain plates and the composite veneers through adhesives in sequence from top to bottom, and performing hot press molding to obtain a PB plate initial product;
s32, adding the primary PB plate into a cleaning solution, soaking and cleaning for 8-15min, then adding into a treatment solution, soaking for 20-30min, and after soaking, placing into hot air at 55-75 ℃ for air drying to obtain the required PB plate;
the cooking liquor in the step S1 is a compound of tannic acid, hydrogen peroxide and water in a mass ratio of 3-4:1:10-15, the cooking temperature is 78-98 ℃, and the cooking time is 2-3 h;
the treatment liquid in the step S3 is prepared by compounding hydroxypropyl cellulose, ethyl acetoacetate and water according to the mass ratio.
Preferably, the mass ratio of the corn straws to the fir wood in the step S1 is 4-7: 1; the mass ratio of the wood shavings to the adhesive is 100: 7-14.
Preferably, the adhesive in the steps S1 and S3 is prepared by compounding the following raw materials in parts by weight: 25-35 parts of polybutene, 4-8 parts of ammonium polyacrylate, 2-4 parts of lauryl methacrylate, 2-4 parts of ethylene glycol dimethacrylate and 1-3 parts of microcrystalline paraffin.
Preferably, the mass ratio of the polycarbonate to the corn straw fiber to the tosylacetone hydrazone to the ethylene glycol dimethacrylate in the step S2 is 30-50:12-18:1-2: 1-3.
Preferably, the thickness of the adhesive between the composite overlay and the plain plate in the step S3 is 0.05-0.5mm, and the bonding area is 100%.
Preferably, the cleaning solution in the step S3 is prepared by compounding acetone, hydrogen peroxide and water in a mass ratio of 5-6:1: 11-14.
The PB plate odor control process provided by the invention has the following beneficial effects:
1. the method adopts the corn straw mixed with the fir wood as the main raw material to prepare the wood shavings, presses the PB plate, prepares the cooking liquor by compounding the tannic acid, the hydrogen peroxide and the water, treats the raw material, and can effectively remove the smell of the raw material, thereby reducing the smell of the prepared PB plate.
2. According to the invention, the PB plate veneering is prepared by mixing polycarbonate, corn straw fiber, p-toluenesulfonylacetone hydrazone and ethylene glycol dimethacrylate, and the obtained veneering has good wear resistance and sealing property, and can effectively hinder the release of PB plate odor.
