High-density composite fiber board
Technical Field
The invention belongs to the technical field of composite fiber boards, and particularly relates to a high-density composite fiber board.
Background
The ecological balance for protecting the nature is the most concerned hot point problem at present in the world, and the recycling of agricultural straw wastes becomes the focus of attention. The straw resources in China are quite rich, mainly straws of rice, wheat and corn, but the treatment mode of the crop straws is mainly to directly burn the crop straws, so that not only useful resources are wasted, but also serious environmental pollution is caused, and the major reasons for repeated prohibition are that the comprehensive utilization of the straws is poor, and key technical problems are not broken through. Therefore, how to reasonably and effectively utilize plant straws is not only a strategic subject in the agricultural industry, but also becomes a focus of attention of relevant government departments.
With the continuous and deepened implementation of national policies of environmental protection and sustainable development, how to utilize building wastes as resources has become an important technical and social subject. Since setting and hardening of concrete is a very slow process, even after 20 years, hydration of cement has not been completely completed, and related studies have revealed that the construction waste has an activity index of 66%. Therefore, the method has important significance in improving the high value-added utilization of the construction waste.
Some technical schemes of high-density fiberboard also appear in the prior art, for example, a chinese patent with application number 201510414379.5 discloses a whitening composite high-density fiberboard, which is prepared from the following raw materials in parts by weight: 42-45 parts of crop straws, 30-32 parts of wood leftover materials, a proper amount of 2% sodium hydroxide, 20-22 parts of 10% hydrogen peroxide, 2-3 parts of sodium silicate, 1-2 parts of magnesium sulfate, 2-2.5 parts of a silane coupling agent kh450, 66-70 parts of 95% ethanol, 7-8 parts of a water-based polyurethane adhesive, 1.5-2 parts of emulsified paraffin, a proper amount of water and 1-2 parts of a pure acrylic emulsion; mainly use suitable timber leftover bits and pieces and crop straw as the raw materials among this technical scheme, wherein timber leftover bits is longer because ligneous growth cycle, the price of timber leftover bits is far above the crop fibre, manufacturing cost increases substantially, crop straw's intensity is lower simultaneously, and the fibreboard that produces only has the one deck, can't provide stronger impact resistance, and its fibreboard itself intensity is serious not enough, and life is short, simultaneously along with the increase of live time, the limiting plate surface very easily produces mould, can lead to the inside corruption of fibreboard to appear when influencing pleasing to the eye.
In view of this, the present invention provides a high-density composite fiberboard, which has high toughness, strength and anti-impact capability through different materials and production methods for the face plate and the core plate, and simultaneously has a long service life, and the designed processing device is used to perform special processing on the raw material, so that the tightness of each substance in the raw material can be further improved, and the high-density composite fiberboard has high toughness, strength and anti-impact capability.
