Problems solved by technology

[0003] In the waterproof construction, the base layer with complex shape needs to be spliced ​​in multiple pieces. It is difficult to bond the overlapping parts of the waterproof membranes. Complete sealing becomes the main problem, and the hidden danger of water leakage is great.
High-grade waterproof membranes have durability for decades, but there is no matching adhesive at home and abroad. Due to the environment and the factors of the adhesive material itself, the bonding function is often lost in advance, generally 5-7 years at most. life

preparation example Construction

[0035] A corrugated asphalt waterproof board in this embodiment, the corrugated asphalt waterproof board is made by using wood fiber as a raw material, spraying glue on the surface to make a corrugated tile shape, and then impregnating asphalt. Its preparation method specifically comprises the following steps:

[0036] 1) Make wood pulp into a slurry with a concentration of about 2% (mass fraction), and then use special equipment to copy the slurry into a quantitatively uniform (uniform density) substrate, press and dry the substrate to A board with a moisture content of 8% was obtained;

[0037] Among them, before the plate is dry, the patterns are pressed on both sides; the surface of the plate is sprayed with glue before the plate is dried; the glue sprayed is made of special glue to control the water absorption of the plate and the amount of asphalt impregnation;

[0038] 2) Press the dried plate into a corrugated tile shape at a high temperature of about 250°C;

Abstract

The invention discloses a corrugated asphalt waterproof board. The corrugated asphalt waterproof board is made by using wood fiber as a raw material, forming into a corrugated tile type after performing glue spraying on the surface, and performing impregnation with asphalt. Compared with the coiled material with the expansion and contraction by its own material, due to the corrugated structure andthe self-material expansion and contraction under the frequent changes of temperature, the corrugated asphalt waterproof board of the invention has higher fatigue resistance, the waterproof life which is at least 5 times longer than that of the coil material, and the service life which is at least 25 years (while the quality insurance of the waterproof coiled material is generally within 5 years); the corrugated asphalt waterproof board of the invention has a waveform of a special size and can bear more than 180 kg per square meter; the wood fiber is used as the tire base to enhance the flexibility of the waterproof board so as to enable the waterproof board of the invention to be resistant to repeated folding like paper, thereby achieving strong impact resistance; the corrugated structure is favorable for roof ventilation and dehumidification; the waterproof board of the corrugated structure of the invention is in line contact with the base or partially in surface contact with the base, the position of the corrugated structure is raised and suspended, and the heat dissipation effect is greatly improved compared with the coiled material; and the construction and the replacement are convenient.

Description

technical field [0001] The invention relates to the field of waterproof boards, in particular to a corrugated asphalt waterproof board. Background technique [0002] At this stage, asphalt waterproofing membrane is commonly used for roof waterproofing, which generally uses SBS rubber modified petroleum asphalt as the impregnated covering layer, polyester fiber non-woven fabric, jute cloth, glass fiber mat, etc. as the base, and plastic film as anti-sticking The isolation layer is compositely formed through material selection, ingredients, eutectic impregnation. During construction, glue is applied to the building base and the surface of the coiled material. In order to enhance the bonding effect, sometimes high temperature bonding is used. [0003] In the waterproof construction, the waterproof membrane needs to be spliced ​​in multiple pieces for the base layer with complex shape. It is difficult to bond the overlapping joints of the waterproof membrane. Complete sealing h...
