One end of a structural formula of the aluminate asphalt cement waterproof bridging agent can be connected with arboxyl or esteryl to form relatively good chemical affinity; the other end of the aluminate asphalt cement waterproof bridging agent can be bonded with hydrated calcium silicate or calcium aluminate generated in a cement hydration process to form a chemical bond; and the chemical bond and the concrete generate chemical cross-linking reaction just like forming a bridge for tightly connecting the asphalt and the cement into an integer; chemical bond actions exist in relevant parts, and make reversible bonding effects after curing. The waterproof bridging agent can be made into a waterproof roll or prepared into waterproof paint, waterproof cream or a waterproof plugging agent. In a cement curing process, the waterproof bridging agent can permeate into pores of cement gel and the concrete, thereby achieving tight and firm fastening and reversible bonding effects as flesh and blood.
Description
Technical field
the present invention relates to a kind of additive of building operation water-proof material, particularly can carry out chemical crosslink reaction with pitch and cement simultaneously, form the chemical bond of good chemical affinity, make it to solidify after play the bridging agent of irreversible cohesive action and waterproof product thereof and application.
Background technology
common building operation water-proof material mainly cement and pitch, pitch is mainly used in the gap plugging on concrete seam or wall limit, or is layered on the leakproof of roof bonding splits, also can make waterproof roll, be laid on the occasion needing antiseepage rainproof.But current pitch is difficult to carry out good leak stopping leakproof, its reason is pitch is very unabiding with the bonding of the cement (concrete) that have cured, mainly pitch is the residue after oil extracts gasoline, kerosene etc., and great majority belong to low-molecular-weight alkanes (chemical formula C
n
h
(2n+2)
, n is atomicity) and alkanes is water insoluble, but strong with inorganics stiction force, particularly the pitch crossed of non-modified, easily melting during high temperature, embrittlement during low temperature, experiencing the buildings top layer or surface of exposing to the weather, being very easy to aging coming off.Even if carried out modification to pitch, also cannot ensure and concrete adhesion effect.
how to make the surface of waterproof roll can play good adhesive effect, the applicant Guangxi Jiyusan Waterproof Decoration Co., Ltd. has carried out years of researches, on October 9th, 2009, the patent of invention of " carrying out the waterproof roll that bonding worked in coordination with by chemically crosslinked and physics mortise and tenon with concrete " is applied for, application number: CN200910114456.X open (bulletin) number: CN101694114A to China Intellectual Property Office, a kind of wet paving of this disclosure of the invention overlays waterproof roll, is modifying asphalt mixture is carried out dip-coating on carcass, control thick sizing, overlay film, the techniques such as rolling are made, and described modifying asphalt mixture is modifying asphalt, softening agent, antioxidant, functional aid and weighting agent, matrix pitch is placed in retort by preparation method, adds tackifier, random polyethylene and styrene-butadiene-styrene block copolymer, be mixed evenly, and heats up, and stirs 1.5-2h, then temperature is dropped to about 180 DEG C, then by filler, softening agent, antioxidant, functional aid is added to retort, stirs 0.5-1h, carries out fully mixed and modified, be then transported to colloidal mill, repeatedly grind material, then pitch good for modification is carried out dip-coating on carcass, control thick sizing, overlay film, rolling, what be just prepared into excellent performance carries out the waterproof roll of chemically crosslinked and physics mortise and tenon collaborative bond (ChemicalBondingandPhysicalCrosslinkingSynergism), abbreviation CPS waterproof roll with concrete.
cN200910114456.X discloses that to carry out the functional aid (hereinafter referred to as CPS auxiliary agent) that chemically crosslinked and physics mortise and tenon work in coordination with cohesive action with concrete be poly-methylethoxy base silane or poly-naphthalene formaldehyde sulfonate salt, or both mixtures, in this specification, contriver points out, functionally active auxiliary agent is there is in sizing material due to modifying asphalt mixture, their active group can be formed crosslinked with cement in hydration process, make coiled material and cement slurry or concrete secure bond, this cohesive action is very firm, environment for use factor by coiled material is less, thus it can be bonded on basal plane more enduringly, and form full bonding structure with basal plane, the crosslinking structure that thus two kinds of properties-correcting agent in sizing material are formed with hydrated calcium silicate bonding.Coiled material sizing material layer produces physical adsorption and mortise and tenon effect and is formed with basal plane and bonds in cement solidification process.Cement slurry and water generation hydration reaction, the hydrated product of generation is gathered in the surface formation cohesion film of cement granules.Surface forms plastic gel film formula cement slurry, ensures that it has good mobility, can fill up rough defect on interfacial layer microcosmic, is made the complete wetting formed between coiled material and cement slurry on microcosmic by extruding.After glue-line and cement slurry are fully wetting, make film surface tension force and cement slurry surface tension close, thus make both combine closely, generation physisorption.Meanwhile, the moisture gel film layer that deepens continuously carries out chemical reaction, and thin film layer is inwardly thickened; Being gathered in outside rete to the hydrate of external diffusion by thin film layer makes rete outwards thicken.The speed of infiltrating rete inside due to moisture is greater than the speed of hydrate to external diffusion, and thus produce seepage water pressure, the saturated solution of rete internal water compound outwardly causes rete to break.Breaking of rete makes hydrate contact rapidly and widely with water, reaction is accelerated again, generate the hydrates such as the hydratable silicate gelation system of more amount, calcium hydroxide and aquation calcium sulfate, contact with each other between them and grow into a certain degree, slurry can lose plasticity-completely, set up the reticulated structure be mutually wound around, and constantly produce hydrate in reticulated structure, slurry produces intensity gradually and enters sclerosis formation petrifying water mudstone afterwards.In this process, cement solidification consumes a large amount of water, cause being formed between cement and self-adhesive coiled material in the system of partial closure and produce negative pressure, and the curing exotherm of cement, promote the creep of self-adhesive, make it be deep in concrete kapillary or hole, form physics fourth of the twelve Earthly Branches camphor tree structure, reach reliable bond effect; While self-adhesive glue layer penetrates in concrete kapillary or hole, increase the area that self-adhesive contacts with concrete, promote the fourth of the twelve Earthly Branches camphor tree structure that self-adhesive glue layer and concrete are formed generates more chemical bond, and play " synergistic effect of chemically crosslinked-physics fourth of the twelve Earthly Branches camphor tree ", make basal plane and self-adhesive layer form " interpenetrating(polymer)networks formula " interface structure, thus reach in conjunction with tight, firm, irreversible " skin-type " bond effect technology.Thorough solution modified bituminous pitch coiled material and basal plane cohesive force are large not, and cohesive force is lasting, problem easily affected by environment, achieve the Waterproof structural course that coiled material and basal plane form irreversible, the not impaired integral type that bonds.
