Problems solved by technology

But it also has its inherent disadvantages, because the edges are rough and easy to absorb moisture. In addition, due to the nature of the wood and the properties of the adhesive used, the particleboard of the prior art is not mildew-proof and antibacterial, and it is easy to mold and breed bacteria when used in a humid environment.
In addition, due to the problem of the adhesive used, this kind of particleboard has a certain odor more or less, which affects the quality of the indoor environment in people's lives and is not environmentally friendly.

Embodiment 1

[0046] A method for preparing an antibacterial, mildew-proof and environment-friendly particle board. The particle board includes an upper surface layer, a core layer and a lower surface layer, and the three layers are bonded and hot-pressed for lamination. The preparation method includes the following steps: the first step is to prepare the core layer:

[0047] (1) Raw material preparation: select sawdust, shavings, and waste bamboo fibers, and remove impurities such as sediment, dust, and iron filings through screening and magnetic suction. The mass ratio of sawdust, shavings, and waste bamboo fibers is: 2:1: 3;

[0048] (2) Raw material pretreatment: the raw material in step (1) is crushed, then steamed in a steamer at 110°C for 30 minutes, and then dried until the moisture content is lower than 5.0%;

[0049] (3) Mixing material: Mix the dried raw material and adhesive obtained in step (2) evenly in a mixing machine; the mass ratio of raw material to adhesive is 8:1

Abstract

The invention relates to a preparation method for an antibacterial mould-proof environment-friendly chipboard. The chipboard comprises an upper surface layer, a core layer and a lower surface layer which are bonded and subjected to hot pressing and recombination. The preparation method comprises the following steps that firstly, the core layer is prepared, (1) raw materials are prepared; (2) pretreatment is conducted on the raw materials; (3) the materials are stirred; and (4) mixed materials obtained in the step (3) are subjected to blank packing, primary hot pressing and cooling, and the core layer is obtained; and secondly, the upper surface layer and the lower surface layer are prepared and are both made of single plates with the thickness of 0.8-1.0 mm, the faces, attached to the core layer, of the upper surface layer and the lower surface layer are evenly coated with an appropriate number of adhesives, then the upper surface layer and the lower surface layer are combined with the core layer, and through secondary hot pressing, cooling, edge cutting and polishing procedures, the antibacterial mould-proof environment-friendly chipboard is obtained. Raw materials of an adhesive A and an adhesive B of the environment-friendly adhesives used in the preparation method are selected reasonably, compatibility is appropriate, the prepared adhesives have excellent water resistance and bonding performance, and the drying process is good in uniformity, the smoothness is good, and excellent antibacterial performance, antiatativity and flame resistance are also achieved.

Description

technical field [0001] The invention relates to a preparation method of an antibacterial, mildew-proof and environment-friendly particle board, which belongs to the technical field of building decoration boards. Background technique [0002] The production of particleboard has low energy consumption, low cost, low requirements on the quality of wood raw materials, and good physical and mechanical properties. It is widely used in furniture, decoration, building materials and other industries. In recent years, China has become the world's third largest producer of particleboard after the United States and Germany. Particleboard, also known as particle board, particle board, or bagasse board, is a wood-based panel that is made of wood or other lignocellulosic materials and glued under heat and pressure after applying an adhesive, also known as particle board. [0003] Particleboard has relatively uniform structure and good processing performance. It can be processed into large...
