Abstract
The invention discloses a water-based high-expansion fireproof sealant, which is formed by 38-43% of organic silicon emulsion, 3-7% of waterproof emulsion, 31.6-39% of fire retardants, 8-15.5% of fillers, 0.5-2.5% of expanding agents, 0.3-0.8% of rheological agents, 1-1.6% of antifoaming agents, 0.4-0.9% of dispersing agents, 1.5-2.6% of tackifier and 3.3-5.3% of pigment, and the sum of weight percentage of all the components is 100%. The water-based high-expansion fireproof sealant has good physicochemical performance, flame retardance and environmental protection performance, can meet performance requirements of the sealant field, is simple in preparing method and easy to be produced in industrial mode, and has popularization and application value.
Description
Technical field
The present invention relates to a kind of water-based high-expansion fireproof sealant, belongs to the seal gum technical field.
Background technology
Fireproof seal gum is a kind of more common fireproof blocking sealing material, uses very extensively, is mainly used in the Application Areass such as fire-retardant sealing after buildings fire proof seal, the cable penetration Durchgangshohle.
Existing fireproof seal gum adds halogen flame or inorganic combustion inhibitor usually and obtains flame retardant effect, but generates the hydrogen halide that does not fire during the halogen burning, and environment and human body are produced the secondary injury.Therefore, be necessary to explore a kind of water-based high-expansion fireproof sealant, when guaranteeing that fireproof seal gum has good physicochemical performance, have good flame retardant resistance and environmental-protecting performance again, volume can expand rapidly when meeting fire, stifled full all spaces effectively stop the biography of heat to be replaced, and prevent that the intensity of a fire from stretching and to the harm of human body and environment.
Summary of the invention
At existing in prior technology the problems referred to above and demand, the purpose of this invention is to provide a kind of good physicochemical performance that both had, have the water-based high-expansion fireproof sealant of good flame retardant resistance and environmental-protecting performance again, for this area increases a class product innovation.
For achieving the above object, the technical solution used in the present invention is as follows:
A kind of water-based high-expansion fireproof sealant, the weight percent that it is formed and each is formed is as follows:
Above-mentioned each weight percent sum of forming is 100%.
The preferred phenylpropyl alcohol water-proof emulsion of described water-proof emulsion.
Described fire retardant is selected from any one or a few the combination in ammonium polyphosphate, antimonous oxide, aluminium hydroxide, tetramethylolmethane, the trimeric cyanamide.
Described filler is selected from any one or a few the combination in silicon powder, china clay, talcum powder, mica powder, the halloysite powder.
Described swelling agent is selected from any one or a few the combination in expanded graphite, expanded vermiculite, the plastic expansion particle.
Described tackifier are selected from modification tackify rosin milk or vinylformic acid-methacrylic ester emulsion or its both combination.
A kind of preparation method of described water-based high-expansion fireproof sealant comprises the steps: to take by weighing each component by proportioning; Organic silicon emulsion, water-proof emulsion, defoamer, dispersion agent are added in the kneader, stirred 10～20 minutes down at 10～40 ℃; Add fire retardant, filler, rheological agent, swelling agent and pigment again, stirred 1～2 hour; Add tackifier then, vacuumize and heat and slowly be warming up to 40～50 ℃, maintenance vacuum tightness is-0.06 ± 0.02Mpa, and insulated and stirred 1～2 hour, namely gets described water-based high-expansion fireproof sealant.
Compared with prior art, water-based high-expansion fireproof sealant of the present invention not only has good physicochemical performance, and has good flame retardant resistance and environmental-protecting performance.
