Embodiment
Cold-setting bi-component water-proof anti-rot material, be to constitute by two components, comprise that by Resins, epoxy be host, an amount of A component and the liquid polysulphide rubber that adds softening agent and filler composition is host, the an amount of B component that adds catalyzer, filler and pigment composition was A by 1: 1 also: B=1: 1, and blending and modifying constitutes.Product after the modification had both had oil-proofness, resistance to air loss, watertightness and the rubber snappiness of thiorubber excellence, had high strength, high-adhesion and the excellent corrosion resistance nature of Resins, epoxy again.Resins, epoxy in the described A component provides the framework material of high strength and high-adhesion, and the Resins, epoxy after the curing has splendid antiseptic property.According to the E-44 liquid epoxies of performance requriements employing bisphenol A-type, epoxy equivalent (weight) 213-244g/mol is advisable between oxirane value (equivalent/100g resin) 0.41-.47.Consider the viscosity requirement, adding an amount of phthalate is softening agent, and first-selected dibutyl phthalate is low because of its viscosity, intermiscibility good.Liquid polysulphide rubber in the B component, (SH) content 5.9%-7.7% is advisable to adopt thiol group, preferably adopt 6.6-7.3% better, with described epoxy blend under the effect of DMP-30 catalyzer, pass through chemical modification, improve the toughness and the shock resistance of Resins, epoxy greatly, also improved the resistance to air loss and the watertightness of product material simultaneously.DMP-30 in the B component, promptly 2.4.6-three (dimethylaminomethylphenol) is the catalyzer of thiorubber and Resins, epoxy chemical reaction, also is curing agent for epoxy resin simultaneously.At normal temperatures, spontaneous curing need not heated.Selected filler can adopt talcum powder, lime carbonate, ground silica, wherein be that the best talcum powder that uses can prevent pigment precipitation caking with the talcum powder, also can prevent coating flowing hanging and be full of cracks, water tolerance, wear resistance, weather resistance and brushing property that raising is filmed are beneficial.Can add in the B component that iron oxide red, iron are green, pigment such as carbon black and titanium white, be mixed with red, orange, black, white, silver color and the multiple colo(u)r coating of grey easily, to satisfy the needs of different purposes.
The compound method of cold-setting bi-component water-proof anti-rot material, shown in Fig. 1 technological process of production figure:
The preparation of A component
Form successively accurately weighing Resins, epoxy by prescription, softening agent and filler, order adds in the tempering tank, and is even with mechanical stirring, then with compound through colloidal mill, fine grinding three times reaches uniform and smooth at every turn and gets final product, logical simultaneously water coolant, the control temperature of charge is at 48 ℃, after sampling analysis was qualified, the discharging barrelling was the A component.
The preparation of B component
Form successively accurately weighing liquid polysulphide rubber, catalyzer, filler, pigment by prescription, order adds in the tempering tank, even with machinery or hand mixing, then with compound through colloidal mill fine grinding three times, reach uniform and smooth at every turn and get final product, logical simultaneously cold water, the control temperature of charge is at 48 ℃, after sampling analysis was qualified, the discharging barrelling was the B component.
Making good two components of A, B needs separated deposit standby.Want strict A: the B=1 that press in use: 1 proportioning, A, B two components are mixed, and stir, no color differnece, can construct, in effective working life, using up.Otherwise can lose efficacy because of the sizing material curing gel.
After A, B two components mix, at 1-2 hour inner gel, just solidify in 24 hours, completely solidified can be used after seven days.Construction temperature is preferably in more than 15 ℃, is lower than 15 ℃ or winter to want corresponding prolongation set time at outdoor construction.
