A fireproof insulation board and its preparation process

Abstract

The invention discloses a fireproof thermal-insulation board. The fireproof thermal-insulation board is prepared from cement, quartz sand, perlite, foam grains, pearl sand, limestone flour, slaked lime, rubber powder, zinc stearate, industrial calcium zinc powder, an air entraining agent, mortar king and separating powder through primary stirring type fermentation and a secondary fermentation technology, wherein the cement has excellent fireproof performance, the quartz sand has fireproof thermal-insulation performance, the perlite, the foam grains and the pearl sand have excellent thermal-insulation performance, the pearl sand, the limestone flour and the slaked lime are capable of improving product strength, the rubber powder and the zinc stearate have waterproof and dampproof performance, the industrial calcium zinc powder is capable of improving cracking resistance, the air entraining agent is capable of improving product homogeneity, and the mortar king is capable of improving workability of mortar. Thus, the fireproof thermal-insulation board has the advantages of lightweight, thermal insulation, sound insulation, fireproofing, dampproofing and resistance to cracking, hollowing and shedding.

Description

technical field [0001] The invention relates to the field of building materials, in particular to a fireproof insulation board and a preparation process thereof. Background technique [0002] Thermal insulation of building exterior walls is one of the important methods to realize building energy saving. Existing thermal insulation materials for external walls are mainly prepared from organic foam materials such as polystyrene particles, polystyrene boards, polyurethane boards, and extruded boards as thermal insulation materials. These organic materials have the advantages of small thermal conductivity, small bulk density, and good toughness, and have been widely used in my country for more than ten years. However, these materials burn quickly when they encounter a fire source, and emit a large amount of toxic smoke. So once the outer wall of the building is on fire, it will be difficult to extinguish it in time, which will cause a large number of casualties and property lo...

However, these materials burn quickly when they encounter a fire source, and emit a large amount of toxic smoke

Therefore, once the outer wall of the building is on fire, it is difficult to extinguish it in time, which will cause a large number of casualties and property losses.

In order to improve the fireproof performance of insulation boards, various new inorganic wall materials such as cement lightweight partition boards, aerated concrete blocks, ceramsite blocks, and activated carbon walls have appeared in the society in recent years. The insulation performance of these materials is poor, and the insulation board materials prepared by the foamed cement concrete system have insufficient toughness, poor waterproof performance, and difficult to guarantee the later strength

[0003] The Chinese patent application publication number CN104960268A discloses a nest type thermal insulation board and its preparation method, which uses special formula and preparation method to make the attachment slurry layer, bridge blocking slurry layer, Insulation slurry layer, anti-cracking slurry layer and decorative slurry layer, although the thermal conductivity of the nest type thermal insulation board is low, the thermal insulation performance is good, and the firmness of the plate has also been strengthened, but it needs to be processed separately during production. The slurry layer is prepared, and then 15-25 parts of the attachment slurry, 1-3 parts of the bridge blocking slurry, 140-160 parts of the thermal insulation slurry, 3-9 parts of the anti-cracking slurry and 15 parts of the decorative slurry are prepared according to the parts by weight. - 25 parts from the bottom layer to the outer layer are evenly laid in the initial molding system for initial molding. After the initial molding, curing, trimming, steam curing and drying steps are required, which has complex process flow and high energy consumption. defect
