Problems solved by technology

[0004] In recent years, some domestic and foreign methods have been developed to replace wood-based panels with wood scraps and crop stalks. However, the existing panel-making methods are not perfect, such as single raw materials and rough manufacturing methods. The problem is that unfavorable factors are not considered in the manufacturing process: the problem of high sugar content, if not treated, will affect the physical and mechanical properties of wood-based panels such as water absorption, strength, and the amount of adhesive will be large, too much sugar If the content is not reduced, it will be easily eroded by fungi, and fermentation will affect the fiber strength. When it is damp in rainy days or the ground is soaked in water, the wood-based panel will provide a good living environment for the fungus, resulting in mildew of the wood-based panel

Embodiment 1

[0021] A method for making wood-based panels using wood scraps and straws, comprising the following steps: (1) pretreatment of miscellaneous wood and wood scraps: taking miscellaneous wood and wood scraps to be pulverized and sieved into cellulose particles with a particle size of 30 meshes, and the wood The cellulose particles were soaked and washed in urine oxygen solution (the molar mass ratio of urea to hydrogen peroxide was 3:5, and the weight ratio of wood fiber particles to urine oxygen solution was 1:10) at constant temperature for 30 minutes, soaking temperature was 45°C, and then added cellulose Degumming treatment with enzyme and pectinase and filtration, drying at 105°C for 4 hours, adding polylactic acid and vacuum drying at 45°C; (2) Pretreatment of crop straw: take the crop straw and put it into a mill for grinding, and then sieve After treatment, 30-mesh straw cellulose particles were obtained, which were degummed by adding cellulase and pectinase, filtered, and...

Embodiment 2

[0026] A method for making wood-based panels using wood scraps and straws, comprising the following steps: (1) pretreatment of miscellaneous wood and wood scraps: taking miscellaneous wood and wood scraps to be pulverized and sieved into cellulose particles with a particle size of 30 meshes, and the wood The cellulose particles were soaked and washed in urine oxygen solution (the molar mass ratio of urea to hydrogen peroxide was 2:5, the weight ratio of wood fiber particles to urine oxygen solution was 1:5) and soaked and washed for 30min at a constant temperature. Degumming treatment with enzyme and pectinase and filtering, drying at 90°C for 6 hours, adding polylactic acid and vacuum drying at 45°C; (2) Pretreatment of crop straw: take the crop straw and put it into a mill for grinding, and then sieve After treatment, 30-mesh straw cellulose particles were obtained, which were degummed by adding cellulase and pectinase, filtered, and dried at 120°C for 4 hours. The dried stra...

Embodiment 3

[0031] A method for making wood-based panels by using wood scraps and straws, comprising the following steps: (1) pretreatment of miscellaneous wood and wood scraps: taking miscellaneous wood and wood scraps to be crushed and sieved into cellulose particles with a particle size of 40 meshes, and the wood The cellulose particles were soaked and washed in urine oxygen solution (the molar mass ratio of urea to hydrogen peroxide was 3:4, and the weight ratio of wood fiber particles to urine oxygen solution was 1:15) for 50 minutes at constant temperature, the soaking temperature was 30°C, and then the fiber Sulfase and pectinase were degummed and filtered, dried at 120°C for 4 hours, added polylactic acid and dried in vacuum at 30°C; (2) Pretreatment of crop straw: take the crop straw and put it into a mill for powder treatment, after sieving After sub-treatment, 40 mesh straw cellulose particles were obtained, which were degummed by adding cellulase and pectinase, filtered, and dr...

Abstract

The invention discloses a method for making an artificial board with wood leftover materials and straw. According to the method, the wood leftover materials and the straw are used as raw materials to make the artificial board. Compared with a common artificial board, the artificial board is more environment-friendly, the ageing resistance, anti-bacterial property, corrosion resistance, flame retardant property and water resistance are more excellent, and the service life is longer. Moreover, the wood leftover materials and crop straw can achieve waste recovery, so that production cost of the artificial board is reduced, and social benefits and economic benefits are remarkable.

Description

technical field [0001] The invention relates to the technical field of artificial board manufacturing, in particular to a method for making artificial boards by using wood leftovers and straws. Background technique [0002] The application of wood in people's life is ubiquitous, such as furniture, floor boards, door and window frames, etc. It is also widely used in industry and agriculture. However, these applications have caused a large number of trees to be felled, seriously damaging the ecological environment. However, the utilization rate of leftovers produced in the production process of wood products is extremely low. These leftovers are generally burned as fuel, resulting in a great waste of resources, and even randomly placed in any corner of the factory, affecting the working environment. In addition, my country is a large agricultural production country, and the utilization rate of straw in agricultural production is also extremely low. Most of them are burned and ...
