Abstract
The asphalt liquefying agent is formed from 14-50% of naphthenic oil, 20-62% of chlorinated paraffin wax whose chlorinated extent is 42-52% and 14-50% of castor oil. When it is used, after the asphalt is molten, the above-mentioned asphalt liquefying agent, polylol and/or polyamine compound, inorganic filler, catalyst and antioxidant are uniformly stirred and dehydrated to obtain component B; then the polyisocyanate and polyolo are reacted to obtain component A, both two components are mixed uniformly according to the mixing ratio and solidifed, and can be used as water-proof material. Said liquefying agent can raise compatibility of polyurethane, asphalt and inorganic filler, can reduce cost of water-proofing material and can raise product performance.
Description
The invention belongs to field of waterproof materials, specifically is a kind of asphalt liquefier.
Polyurethane waterproof material is a kind of water-proof material of excellent property, but costs an arm and a leg.The main at present materials such as interpolation tar, talcum powder that adopt reduce cost, as U.S. Pat 3,372,083 has introduced a kind of manufacture method of tar polyurethane water-proof material, this method is earlier tar to be handled with polyisocyanates, a kind of performed polymer of resynthesis with the two mixing and adding filler and various auxiliary agent, promptly becomes water-proof material after the curing.Because the consistency of tar and urethane is good, therefore can make the good water-proof material of performance.But owing to contain at least two ten kinds of carcinogenic substances in the tar, wherein the strongest carcinogenic substance has benzopyrene, 2-naphthylamines, 7,12-dimethylbenzanthracene etc., these carcinogenic substances meeting serious harm people's health, so countries in the world all ban use of the tar polyurethane water-proof material one after another.And do not contain carcinogenic substance in the petroleum pitch, thereby become the best substitute of tar.But, because the consistency of petroleum pitch and urethane is very poor, must add some auxiliary agents, otherwise, the poor performance of material.As U.S. Pat 4,795,760 introductions, with 2,3-two penylene base toluene are asphalt liquefier, make bituminous solution, and add a small amount of PAPI (thick diphenylmethanediisocyanate); Behind PPG-MDI (polypropylene glycol-diphenylmethanediisocyanate) performed polymer, BUFC (butyl carbamate-formaldehyde resin) resin mixing, mix with bituminous solution again, promptly get water-proof material after the curing.The shortcoming of this method is that the price of material is higher, because 2, the price of 3-two penylene base toluene is very high, and its consumption can't add cheap mineral filler, so this deficiency is arranged in addition between 7～25%.Japanese Patent JP62-198, introduced another method for 898, this method is earlier synthetic a kind of acrylic polymers, again with the synthetic dispersion agent of this polymkeric substance, use this dispersion agent that about 1: 1 pitch and polyethers are mixed then, high speed dispersion obtains a kind of pitch polyethers and disperses thing, mix, stir evenly with PAPI during use, promptly get water-proof material after the curing.The process of this method is too complicated, and the mechanical property of material is relatively poor.Also useful toluene, dimethylbenzene is as asphalt liquefier, but exists defectives such as toxicity is big, contaminate environment, and the petroleum asphalt modified polyurethane waterproof material poor-performing of preparing.
The object of the present invention is to provide a kind of asphalt liquefier, can improve the consistency of urethane, petroleum pitch, mineral filler, thereby reduce the cost of petroleum asphalt modified polyurethane waterproof material, can obtain preferable performance again.
The objective of the invention is to be achieved through the following technical solutions:
By naphthenic oil 14～50%, chlorination degree is that 42～52% clorafin 20～62%, Viscotrol C 14～50% are formed asphalt liquefier.
After the fusing of 60～No. 180 petroleum pitch, add above-mentioned asphalt liquefier, and add polyvalent alcohol and/or polyamine compounds, mineral filler and catalyzer, anti-aging agent, after stirring evenly, dewatering, make the B component; Wherein, the consumption of petroleum pitch is 15～50% of a B component; The consumption of asphalt liquefier is 6～35% of a B component; The consumption of mineral filler is 15～50% of a B component; The consumption of polyvalent alcohol and/or polyamine is 3～50% of a B component; Catalyst consumption is 0.03～5% of a B component; The consumption of anti-aging agent is 0.05～5% of a B component; The A component is made by polyisocyanates and polyol reaction, its-NCO content is between 2～10%; Wherein, the consumption of polyisocyanates is 8～30% of an A component; The consumption of polyvalent alcohol is 70～92% of an A component.
Above-mentioned polyvalent alcohol can be a polyethers (as: PPG-330), 1,4-butyleneglycol (BDO), TriMethylolPropane(TMP) (TMP), polyester, polyacrylic ester etc.
Above-mentioned polyamine compounds can be 3,3 '-two chloro-4,4 '-ditan diamines (MOCA) etc.
Above-mentioned mineral filler can be talcum powder, wollastonite, kaolin, lime carbonate etc.
Above-mentioned catalyzer can be dibutyl tin laurate, stannous octoate, lead octoate 36 etc.
Above-mentioned anti-aging agent can be 2,6-di-tert-butyl-4-methylphenol, four [β-(3,5-di-tert-butyl-4-hydroxy phenyl) propionic acid] pentaerythritol ester, antioxidant H etc.
Above-mentioned polyisocyanates can be tolylene diisocyanate (TDI), diphenylmethanediisocyanate (MDI), PAPI, isophorone diisocyanate (IPDI) etc.
During use with A, B two components in A: B=1: 0.5～1: 3 ratio mixing, coat on the base material, solidify the water-proof material that a week promptly gets a kind of excellent property.
After the above-mentioned petroleum pitch fusing, add polyvalent alcohol and/or polyamine compounds, mineral filler and catalyzer, anti-aging agent, after stirring evenly, dewatering, make the B component and can adopt other prescription, other processing condition of prior art etc. by the process that polyisocyanates and polyol reaction make the A component, promptly be not limited only to above-mentioned condition and range, 6～35% the scope of just add-on of asphalt liquefier of the present invention in the B component being controlled at gets final product.
The present invention adopts the compound of naphthenic oil, clorafin, Viscotrol C as asphalt liquefier, this asphalt liquefier can improve the consistency of urethane, petroleum pitch, mineral filler greatly, thereby can reduce the cost of petroleum asphalt modified polyurethane waterproof material greatly, can obtain preferable performance again.
