Abstract
The invention relates to a building material, especially building gap-filling glue having a function of both water resistance and back-fire relief and the method for preparation. The gap-filling glue is prepared by mixing bulging water-proof colloid with bulging fire retardant and stirring, the weight ratio of said bulging water-proof colloid being 50-75%, and said bulging fire retardant being 25-50%. The prepared gap-filling glue having a function of both water-proof and back-fire relief expands the function of present only water-proof building gap-filling glue, having a function of back-fire relief.
Description
Technical field:
The present invention relates to a kind of material of construction, particularly a kind of building gap-filling glue that has waterproof and back-fire relief function concurrently and preparation method thereof.
Background technology:
The buildings waterproof filler is because closely bound up with daily life, therefore constantly developed, existing water-proof material particularly waterproof glue develops to the direction of water-swelling gradually, a kind of hydro-expansive rubber that is made by water uptake expansion resin and preparation method thereof is disclosed as Chinese patent application 200410014542.0, the hydro-expansive rubber that this method makes has good water-swellable performance, meeting water does not have precipitate, seeps water, leaks in the slit that can stop effectively to be filled.But these water-proof materials do not possess the function of back-fire relief, because these water-proof materials all have permeability, so fire is when taking place, and hot cigarette can see through the ventilative micropore of water-proof material in the slit scurry close region, causes fire spread.In the existing various building structure simultaneously, various slits such as expansion joint, settlement joint, interface seam etc. also all are the fp weak links, during presence of fire, cigarette, fire are easy to scurry to the building structure that closes on from these slits, cause spreading of fire, the numerous fire in the whole world causes the accident of personnel's heavy casualties to be mostly because the intensity of a fire can not effectively be completely cut off in the finite space at present, spreads as various slits by various fire prevention weak links and causes.Along with the whole world is more and more higher to the requirement of building structure fp, the fire prevention in various slits is handled also becomes the work that must finish in the building structure.
Summary of the invention:
The present invention solves the defective that above-mentioned material of construction can not have waterproof and back-fire relief function concurrently, design a kind of can water-swellable, also can meet the gap-filling glue of fiery expandable flame retardant, the invention still further relates to the preparation method of this gap-filling glue.
The object of the present invention is achieved like this: a kind of gap-filling glue that has waterproof and back-fire relief function concurrently, it is characterized in that, mix together by expansion waterproof colloid and expanding fire retardant, wherein said expansion waterproof colloidal weight percent is 50-75%, and the weight percent of described expanding fire retardant is 25-50%.
Described expansion waterproof colloid is the mixture of water uptake expansion resin and EPDM rubber, and its weight percent is respectively 20-40% and 60-80%.
Described expanding fire retardant is the based carbon fiber flame-retardant system, and described based carbon fiber flame-retardant system is the fire retardant that contains N, P, C, and N, P, the C content (weight percent) in fire retardant is respectively N:5-10%, P:5-15%, C:3-10%.The based carbon fiber flame-retardant system of described N, P, C content range is to be mixed by chemical agents such as tetramethylolmethane, Mei Naiming, ultrapas, expansile graphites.
The form of described gap-filling glue is the mud shape, with water uptake expansion resin with mix together with expanding fire retardant again after EPDM rubber mixes according to the above ratio.
The form of described gap-filling glue is a strip, and the gap-filling glue of above-mentioned one-tenth mud shape by the forcing machine extrusion molding, is carried out gum then, and last itemize becomes the finished product of various demand shapes.
The present invention mixes the colloid of water-swellable and the material of the fiery expandable flame retardant of chance dexterously, obtained the gap-filling glue that not only has water resistance but also have the back-fire relief function, the function of the gap-filling glue of the simple waterproof that existing building uses is expanded, has had the back-fire relief function.When meeting water, gap-filling glue of the present invention firmly seals the slit by at least two-triple expansion multiplying power, and anti-sealing sees through the slit; And when fire, gap-filling glue of the present invention can expand again and charing, and fire, cigarette, hot gas all can't be passed through, and reaches fire-retardant effect.Particularly, gap-filling glue can be made the strip of gum, can post up various slit aperture, also can be posted in door limit, the window limit of frequent folding, expansion charing when presence of fire is firmly sealed crack between a door and its frame, window limit, flame is pinned in limited space, fire must not be spread.
Embodiment:
The present invention is further elaborated below by the embodiment that does not limit.
Embodiment 1: present embodiment is a preferred embodiment: with weight is that commercially available EPDM (Ethylene Propylene Terpolymer) rubber of 3 kilograms commercially available water uptake expansion resin and 7 kilograms is in reactor behind the normal temperature thorough mixing, the expanding fire retardant that adds 10 kilograms, and thorough mixing, obtain higher relatively mud shape (glue) gap-filling glue of viscosity, extrusion or penetrate sheet on common forcing machine then, and by the gum processing, last itemize obtains the strip gap-filling glue that can put up.The strip gap-filling glue is convenient to cut out, and can be posted in various door and windows limit, various sealing, and has the effect of meeting water and meeting fiery expandable flame retardant, thereby prevents to leak and fire spread.Above-mentioned expanding fire retardant is commercially available expanding fire retardant, be preferably compound based carbon fiber flame-retardant system, described based carbon fiber flame-retardant system is the fire retardant that contains N, P, C, and N, P, the C content (weight percent) in fire retardant is respectively N:5-10%, P:5-15%, C:3-10%.Described based carbon fiber flame-retardant system is by commercially available aminoresin, chemical agent such as phosphoric acid and ultrapas mixes, different concns according to the next chemical agent of above-mentioned purchase makes up, make N in the based carbon fiber flame-retardant system, P, the weight percentage proportional range of C is N:5-10%, P:5-15%, C:3-10%, the gap-filling glue that is mixed with mentioned component and ratio based carbon fiber flame-retardant system has higher burning expansion multiplying power, this is N, after being heated, P produces the result of gas, carbonization expansion rapidly after promptly being heated, the existence that is the C element makes burning form the carbonization expanding layer, thereby do not produce and drip to hang down, and burning is tight more more, can effectively prevent dense smoke thereby have, flame, the back-fire relief that hot gas and toxic gas diffusion spread presses down cigarette, cut the fire spreading function.Expanding fire retardant also can be selected poly-charcoal source, the gentle monomer expanding fire retardant that comes from one of acid source for use, as bicyclic phosphate-phosphoramide types fire retardant.
