Description
Technical field
The present invention relates to building technical field, be specifically related to the preparation method of the fire-retardant coating composition of a kind of building.
Background technology
In recent years, along with developing rapidly of Chinese national economy, building trade flies suddenly as mainstay of the national economy industry is naturally prominent
Entering, and the relevant energy consumption built also becomes abnormal huge, the energy directly consumed during building and using accounts for whole society's total energy
The 30% of consumption.Along with country to energy-conservation, the pay attention to day by day of reduction of discharging sustainable development, in building trade and other associated row
Industry constantly occurs in that all kinds of insulating moulding coating, thermal insulation coatings, as polystyrene board and glue powder polyphenyl particle, polyurethane foam etc. are incubated
System, though heat-insulation and heat-preservation can be realized, but product also exists the shortcomings such as construction complexity, poor, the not fire prevention of water proofing property, especially with respect to anti-
The performance that fire is fire-retardant, concerning the security of the lives and property of people, gas can not reach far away people's expection for fire protecting performance.
Architectural fireproof paint is mainly used in being coated on building surface, and when meeting fire, film itself is difficult fires or does not fires, and has substrate
Preferably protective effect, withdraws for fire extinguishing and personnel and has won valuable time, and therefore research and application to it increasingly become
The focus of building field.The research starting of China's fireproof flame-retardant coating is late, and current fireproof coating mainly has two kinds, and one is to adopt
Being base material with the organic polymer of difficulty combustion, another is then to add fire retardant at coating, and representative halogen system, phosphorus system prevent
Fire coating be in development, but in halogen system some bromine class fireproof coatings because of environmental issue the most controversial.And for inorganic
Although fireproof coating can stand the baking of high temperature, but its existence attachment is poor, the defects such as intensity is low, and film is more crisp.Except upper
Stating the serviceabilities such as fire line, architectural fireproof paint also requires easy act, because the shape of building is the most sufficiently complex, adds
The structure member part that be combined with each other be difficult to especially apply in advance, it is necessary to site operation coats, so architectural fireproof paint
Must have suitable easy act, or the fewest painting is coated with reducing engineering time or number of times.Simultaneously along with people are for life
The continuous pursuit that quality of living improves, people are for the aesthetic property also growing interest of building, and this just requires that architectural fireproof paint is full
Foot fire prevention, easy construction etc. also must keep the outward appearance style and features of building as far as possible while requiring.
The acrylic compounds aqueous fire-proof coating being widely studied at present, the Chinese patent such as Publication No. CN101100576A is open
A kind of fireproof coating, its mass percent composition is as follows: acrylic emulsion 26.0%～33.0%, APP 12.0%～
16.0%, tetramethylolmethane 4.8%～13.2%, tripolycyanamide 2.0%～5.0%, expansible graphite 2.0%～5.0%, hydrogen-oxygen
Change aluminum 8.0%～12.0%, defoamer accounts for 0.20%～0.50%, and levelling agent accounts for 0.20%～0.30%, dispersant account for 0.20%～
0.40%, plasticizer accounts for 2.0%～3.0%, and coupling agent accounts for 0.1%～0.2%, and thickening agent accounts for 0.8%～1.5%, then adds water
To 100%.Although above-mentioned fireproof coating or other similar coating exist the advantages such as environmental protection, but it is in fire line, water proofing property, resistance to
The aspect such as Hou Xing, aesthetic property is still difficult to meet the architectural fireproof paint requirement day by day improved.
