Fire-proof sound insulation shock-proof plate and its producing method

Abstract

The disclosed board includes a wood-fiber layer and a cement layer. Pressing majority of wood-fiber with mixed calcium chloride, fire retardant, and a little cement produces wood-fiber layer. Mixing cement with resin produces the said cement layer. The inner side of cement layer is bonded to one side of the wood-fiber layer. The method includes following fabricating steps: first, cutting wood to fiber; next, pressing mixed calcium chloride, fire retardant, and cement produces tabular wood-fiber layer; then placing wood-fiber layer into die with cement and resin being filled to; finally, drying and molding.

Description

Technical field [0001] The invention relates to a building material, in particular to a fire-proof, sound-proof and anti-vibration board with simple construction and a manufacturing method thereof. Background technique [0002] The walls of general buildings are usually made of brickwork or cement grouting and then smeared with cement on both sides. However, the brickwork method requires manual piling up one by one, which is quite time-consuming and laborious, while the cement grouting method requires the wall to be erected in advance. After the cement grout is poured in and dried, the wall formwork is removed. This is also quite time-consuming and laborious. The walls made of brickwork or cement grouting usually have considerable thickness and occupy a lot of space, so it is very Not suitable for use as a partition wall. [0003] Therefore, some manufacturers are thinking of replacing them with light-weight boards. After assembling most of the light-weight boards piece by piece,...

[0002] The walls of general buildings are usually made of bricks or cement grouting, and then smeared cement on both sides to level them. After the cement grout is poured in and dried and shaped, then the wall formwork is removed, which is also quite time-consuming and laborious, and the walls made of bricks or cement grouting usually have a considerable thickness and take up a lot of space, so it is very Not suitable for use as a partition wall

[0003] Therefore, some people in the industry think of replacing them with light and solid boards. After assembling most of the light and solid boards one by one and then smearing cement on both sides to form a wall, this will not only save time and effort when assembling the wall, but also reduce the cost of the wall. In addition, the walls usually need to have functions such as fire prevention, sound insulation, and heat insulation to have a certain degree of safety and privacy. Generally, the most common light-weight board on the market is calcium silicate board, which has a good fire prevention effect. , but the material cost is too high, and the sound-absorbing effect is not good. In addition, another common light-weight board is wood ore board, which soaks most wood wool in calcium chloride solution to achieve anti-corrosion and lower ignition point, and then combines with Cement is mixed and pressed into a board shape. In this way, the fiber structure of wood wool itself can achieve sound absorption and heat insulation (low thermal conductivity). However, wood ore boards are not as hard as bricks, cement, calcium silicate boards, etc., and The fire-resistant point is not as high as bricks, cement, and calcium silicate boards. Therefore, in use, when the wood ore boards are assembled into a wall, a layer of cement with a considerable thickness must be applied to both sides of the wall to strengthen the fire resistance. Its structure and fire resistance, so a lot of time and manpower will be wasted during construction
