Abstract
The invention relates to a preparation method for a waterproof adhesive. Specific monomer raw materials and a specific ratio are adopted, polymer emulsions having good flexibility, viscosity and stability are obtained through high-temperature polymerization under specific process conditions, and the adhesive prepared through the polymer emulsions has good impermeability, intensity, alkali resistance, corrosion resistance and formaldehyde sealing performance.
Description
Technical field
The present invention relates to a kind of preparation method of waterproof tamanori.
Background technology
Tamanori is widely used in the every field such as communications and transportation, instrument, electronic apparatus, weaving, building, wood working, upholstery, daily necessities now.Existing tamanori remains formaldehyde mostly, larger to human health damage during use.And existing tamanori water-repellancy, wear resistance, weathering resistance are all not strong, thus have impact on the work-ing life of binding agent.
Summary of the invention
In order to overcome the deficiencies in the prior art, of the present inventionly provide a kind of preparation method of tamanori with good strength, solidity to corrosion, water-repellancy.Above-mentioned purpose of the present invention realizes by the following method:
A preparation method for waterproof tamanori, comprises the steps:
A) preparation of polymer emulsion: with weight parts, remove ionized water 100 parts, add in reactor, then add sodium stearyl sulfonate 2 parts successively, dimixo-octyl phthalate 4 parts, emulsifying agent TX-13 2 parts, pH value regulator 2 parts, pentadiene 20 parts, 6 parts, vinylformic acid, mibk 5 parts, methyl methacrylate 10 parts, n-BMA 10 parts, pentanedioic acid 5 parts, ammonium persulphate 1 part, with the ramp to 50 DEG C of 2.5 DEG C/min, abundant stirring 8 hours, again with the ramp to 75 DEG C of 3 DEG C/min, continue fully to stir 5 hours, then add emulsification wetting agent 3 parts, degassed under vacuum, be then 7 by the NaOH solution adjusted to ph that mass percentage is 20%, be cooled to room temperature, obtain polymer emulsion,
B) preparation of tamanori: with weight parts, gets dispersion agent 1 part, defoamer 1 part, nano titanium oxide 20 parts, hot-melt adhesive powder 5 parts, silicon dioxide microsphere 20 parts etc., add in container, then add with the obtained polymer emulsion 40 parts of the step a) of weight parts, dispersed with stirring, then add 2.5 parts of wilkinites, filler 5 parts, continues stirring 2 hours, then grinds 2h, filter, obtain waterproof tamanori.
Well-beaten stir speed (S.S.) in step a) is 400 turns/min, and rate of temperature fall is 3 DEG C/min.
Stir speed (S.S.) in step b) is 400 turns/min, adopts tamanori strainer to filter.
beneficial effect of the present invention
Silicon dioxide microsphere and nano titanium oxide is employed in tamanori, silicon dioxide microsphere and nano titanium oxide surface are by after methyl methacrylate-modified, use it in tamanori, each Interaction of substituents in the polymkeric substance on modified silicon-dioxide and nano titanium oxide surface and pentadiene, vinylformic acid, mibk, sodium stearyl sulfonate, significantly add the hardness of tamanori, intensity and scratch resistance, extend work-ing life.
Dimixo-octyl phthalate, sodium stearyl sulfonate, n-BMA, pentanedioic acid act synergistically each other, enhance the wrinkle resistance of tamanori, deformation resistance, water-repellancy, scratch resistance, weathering resistance greatly, and elasticity obviously promotes, serve the effect of closed methanal simultaneously, the burst size of formaldehyde is significantly reduced.
Embodiment
Below in conjunction with embodiment, the present invention is further described.
