Abstract
The invention discloses an aqueous elastic fireproof jointing sealant. The sealant is composed of 38-43% of organic silicon emulsion, 3-7% of waterproof emulsion, 31.6-39% of flame retardant, 8-15.5 of filler, 0.3-0.8% of rheological agent, 1-1.6% of antifoaming agent, 0.4-0.9% of dispersant, 1.5-2.6% of tackifier and 3.3-5.3% of pigment, wherein the sum of weight percentages of the components is 100%. The aqueous elastic fireproof jointing sealant disclosed by the invention has good physical and chemical properties, excellent flame retardance and environmental friendliness, and can satisfy performance demand of the field. In addition, the sealant of the invention is simple in preparation method and easy for industrial production, and has wide application value.
Description
Technical field
The present invention relates to a kind of aqueous elastic fire prevention joint filling seal gum, 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, environment and people is known from experience produce the secondary injury.Therefore, be necessary to explore a kind of aqueous elastic fire prevention joint filling seal gum of not halogen-containing and sulphur, when making it guarantee that fireproof seal gum has good physicochemical performance, have good flame retardant resistance and environmental-protecting performance again.
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 aqueous elastic fire prevention joint filling seal gum 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 aqueous elastic fire prevention joint filling seal gum, 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 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 aqueous elastic fire prevention joint filling seal gum 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, 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 aqueous elastic fire prevention joint filling seal gum.
Compared with prior art, aqueous elastic fire prevention joint filling seal gum of the present invention not only has good physicochemical performance, and has good flame retardant resistance and environmental-protecting performance.
