Description
The technical field is as follows:
the invention belongs to the technical field of building outer walls, and relates to a double-process production line of an assembled fireproof heat-insulation integrated wallboard and a production process thereof.
Background art:
the assembled aerated concrete composite heat-insulation external wall panel is a heat-insulation and structure-integrated composite heat-insulation wall panel which is formed by taking an aerated concrete batten as a base layer, fixing an organic heat-insulation board on the outer side of the base layer through bonding mortar and anchor bolts, pouring a heat-insulation slurry fireproof protection layer and pressing in alkali-resistant gridding cloth, and is hereinafter referred to as the composite heat-insulation wall panel for short.
The existing bonding mortar, thermal insulation mortar and anti-crack mortar layers of the fireproof thermal insulation boards usually use portland cement as a bonding agent, which is called as a portland cement-based composite thermal insulation wallboard hereinafter, and ordinary portland cement can only endure the high temperature of 800 ℃ and has lower strength. If cement used for bonding mortar, thermal insulation mortar and anti-crack mortar is replaced by magnesium oxysulfate cement, and the magnesium oxysulfate cement has higher strength and better fire resistance than portland cement, the produced product plates can have stronger bonding force, better anti-crack performance on the surface, and better thermal insulation effect and fire resistance of a thermal insulation mortar layer, and is hereinafter referred to as a magnesium cement-based composite thermal insulation wallboard. However, due to the change of the formula, the traditional production line of the portland cement fireproof insulation board cannot be used for the magnesium oxysulfate cement-based composite insulation wallboard. If a factory additionally establishes a production line for meeting the requirements of producing different products, the equipment cost can be greatly increased, and the factory building area can be increased.
In addition, the outermost layer of the traditional silicate composite insulation board is generally a process of rolling insulation mortar and grid cloth together, the damage degree of the surface of a product produced by the process is high, and a large number of exposed polyphenyl particle foam beads or cavities exist. Meanwhile, the strength of the portland cement is relatively low, the surface crushing degree can be further increased in the transportation and construction material preparation processes, a large number of residual plates are caused, the residual plates can have high water absorption rate, the risk of swelling and falling is caused when the portland cement is used in rainy areas for a long time, in order to solve the problem, anti-crack mortar is used for repeatedly leveling during construction, and then waterproof putty is coated on the outermost layer. The process adds additional working procedures and increases the construction period. In order to solve the problem, a surface enhanced anti-cracking process that magnesium oxysulfate cement anti-cracking mortar and mesh cloth are coated together is adopted in a double-process production line, and the obtained product has four advantages. Firstly, the surface toughness is high, and the crack resistance is high, and the damage is not easy to happen in the transportation and construction processes. Secondly, the surface integrity is high, the fireproof effect is improved, and the water absorption of the insulating layer is effectively reduced. Thirdly, in the stage of factory prefabrication, the surface enhancement modification can form a special bump effect on the surface of the composite heat-insulation wallboard, and can increase the adhesive force of external slurry, so that the composite heat-insulation wallboard is not easy to crack and fall off. And fourthly, the repeated leveling of anti-crack mortar is not needed during the site construction, and the waterproof putty is directly scraped, so that the construction period is effectively shortened.
Therefore, seek to design a production line that can produce portland cement base and can produce the compound incubation wallboard of magnesium oxysulfate cement base again, can realize that a production line produces two kinds of products, can produce traditional portland cement compound incubation wallboard to satisfy the basic requirement in market, also can produce magnesium oxysulfate cement base fire prevention heated board, in order to satisfy the requirement of market to high-end product.
