Description

A kind of novel mildew resistant silane modified polyether seal glue and preparation method thereof
Technical field
The present invention relates to building sealant technical field, be specifically a kind of novel mildew resistant silane modified polyether seal glue and its Preparation method.
Background technology
Be in the interior decoration of room, as kitchen, bathroom, the sanitary ware of toilet and table top, basement wall etc. this A little more special wet environments, easy mould growth cause decorative coveringn to fade or even come off, and influence building beauty, even Trigger safety problem.It is mouldy also greatly to compromise human health, Long Term Contact and sucking mould can trigger respiratory inflammation and Anaphylactia generates the symptoms such as rhinitis, allergic reaction, pulmonary disease.Therefore, the joint seal of these wet environments, all needs To use the excellent environment-friendly type fluid sealant product of waterproof and fungicidal properties.At present, common kitchen and bath's mildewproof sealant is mostly depickling Type or ketoxime removing type silicone adhesive, addition mould inhibitor are prepared, and the small molecule of these mildewproof sealants removing is with larger Smell, it is irritant to respiratory tract and skin, do not meet environmentally protective requirement.And volume is received after silicone sealant adhesive curing Contracting is big, and elasticity reduces after aging, and the easily cracking, dusting at sealing influences sealing effect.
MS (silane modified polyether) fluid sealant is one of global four big most important sealing materials.MS fluid sealants are in structure The characteristics of inheriting end-silicane-group structure and main chain polyethers bond structure, without solvent, will not pollute adherend, in performance The advantages of combining polyurethane sealant, silicone sealant and polysulfide sealant, i.e., with the good weatherability of silicone sealant Energy and anti-deformational displacement ability, and with the good caking property of polyurethane sealant, paintability and low stain.It is silane-modified Polyether seal glue is a kind of sealing material haveing excellent performance, after there is good fungicidal properties, addition to aid in anti-fungus material for itself, Not only performance is stablized, while plays the role of permanently effective fungus-resistant.
As 104479608 A of Chinese patent CN disclose a kind of preparation of the mould proof silane modified polyether seal glue of environment-friendly type Method.After making resin, plasticizer, filler, colorant, ultraviolet absorber, light stabilizer blending under vacuum protection, thixotroping is added in Agent is stirred under vacuum 30-60 minutes at 50-90 DEG C.Mould inhibitor, deicer, adhesion promoters, catalysis are added in after cooling to 50 DEG C Agent is stirred under vacuum 15-30 minutes, obtains being uniformly dispersed with thixotropic modified silane fluid sealant product.
106987224 A of Chinese patent CN disclose the system that a kind of permanent mould proof silane modified polyether cures fluid sealant soon Preparation Method.Silane-terminated polyether and plasticizer are added in high speed dispersor and are uniformly mixed, vacuumizing and defoaming, then in kneader It is middle to mix the liquid mixture of gained with filler, it is mixed between 100-120 DEG C, vacuumizes dehydration:Again with friendship Connection agent, catalyst, thixotropic agent, moisture scavenger, light stabilizer, adhesion promoters, colorant and mould inhibitor are sufficiently stirred, and are mixed After obtain the permanent mould proof silane modified polyether and cure fluid sealant soon.
107177340 A of Chinese patent CN disclose a kind of transparent single component silane modified polyether sealing of waterproof mould-proof-type Glue and preparation method thereof.The mould inhibitor is the different thiophene beautiful jade -3- ketone of 2- methyl -4-, 5- chloro-2-methyl -4- isothiazolines -3- Ketone, N- octyl group -4- isothiazoline -3- ketone, (bis- chloro- N- octyl groups -4- isothiazoline -3- ketone of 4,5-) isothiazolinone, 2- butyl - Any one in 1,2- benzisothiazole-3-ketones and 1,2 1 benzisothiazole-3-ketones or several combinations.
The mould inhibitor selected by fluid sealant disclosed in existing disclosed document is isothiazolinone, 10,10 '-oxo The organics mould inhibitor such as double phenoxazine arsenic or benzimidazole.Such mould inhibitor has the characteristics that sterilization speed is fast, strong applicability, is Most common mould inhibitor in mildewproof sealant, but there are poor heat resistance, easily decompose and service life it is short the shortcomings of, some also have compared with Strong toxicity and environmental pollution.
As 105111992 A of Chinese patent CN disclose a kind of mould proof silane modified polyether seal glue and preparation method thereof. Mould inhibitor selected by this method is zinc pyrithione, is effectively anti-mildew and antibacterial compound, but zinc pyrithione Unstable to light and oxidant, whens higher temperatures, is unstable to bronsted lowry acids and bases bronsted lowry, after this method adds in mould inhibitor in material, in temperature When vacuum dehydration 2 is small at 110 DEG C, high temperature may reduce the effective performance of mould inhibitor.
106497502 A of Chinese patent CN disclose a kind of silane end capped polyurethane with mould proof net taste effect and are modified Silicone sealant and preparation method thereof.The patent uses anionic polymerization, in SiO2 nanoparticle surface situ-formed graft polycyclics Oxygen propyl alcohol, is combined in base polyurethane prepolymer for use as so that compound seal glue has both the excellent of polyurethane and both silicone sealants Point.Mould inhibitor used is nano-Ag particles, is directly added into system, good anti-bacterial effect, but heavy metal ion in use may The problems such as appearance endangers health of human body, easy xanthochromia.Meanwhile hydroxyl scavenger be hexamethyldisilazane, hexamethyldisilazane It is easy to react with water, decomposites toxic silicide gas or NH3, does not meet environmentally protective requirement.
Therefore, the environmentally protective silane that a kind of fungus-resistant persistence is good, is suitable for interior decoration how is researched and developed to change Property polyether seal glue, is building trade urgent problem to be solved.
The disclosure of background above technology contents is only used for inventive concept and the technical solution that auxiliary understands the present invention, not The prior art of present patent application is necessarily belonged to, shows the applying date of the above in present patent application in no tangible proof In the case of having disclosed, above-mentioned background technology should not be taken to the novelty and creativeness of evaluation the application.
