Problems solved by technology

Due to the short service life of the fire retardant coating, the price is expensive, and it is easy to fall off, the subsequent decoration is required, and the process is complicated
However, to hang the fireproof board, it is necessary to make a light steel keel first, and then fix it on the keel with screws, which increases the construction steps and costs, and is labor-intensive and time-consuming.

Abstract

The invention relates to binder for binding fireproof boards, which is made of, by weight, 23.5%-32.5% of 42.5 portland cement, 5.5%-14.5% of normal high-alumina cement, 41.5%-52.5% of river sand, 5.5%-16.5% of coal ash and 1%-5% of admixtures including reinforcing agent, water reducing agent and water retaining agent. Using the binder to bind the fireproof boards can reduce construction cost and reduce construction procedures, cavities are avoided in binding construction, and heat and sound insulation is effective. The boards after binding have smooth surfaces, suspending meshes for plastering is not needed, and time and cost are saved. Further, integration of fire proofing, heat insulation, sound insulation, decoration and the like is achieved. The binder is especially suitable for fireproof boards to protect steel structures, is simple in manufacturing process and convenient in use, and has high binding force and high temperature resistance.

Description

technical field [0001] The invention belongs to building materials and bonding materials, and relates to materials for protecting steel structure buildings, in particular to a bonding agent and its formula for pasting fireproof boards. Background technique [0002] At present, most of the steel structures are sprayed with fireproof paint and hung with fireproof panels to meet the fireproof requirements of building codes. Due to the short service life of the fire retardant coating, the price is expensive, and it is easy to fall off, the subsequent decoration is required, and the process is complicated. But to hang the fireproof board, you need to make light steel keels first, and then fix them on the keels with screws, which increases the construction steps and costs, and is labor-intensive and time-consuming. [0003] In view of this, seeking a kind of adhesive for pasting fire-resistant boards has become the goal pursued by those skilled in the art. Contents of the inven...
