Description
The present invention relates to a kind of building roofing covering layer material, especially a kind of building marine glue and production technique thereof.
Architectural waterproof material, particularly roof waterpoof material, China all uses asphalt felt for a long time, though release plastic waterproof ointment etc. in recent years, but these materials will heat before use, and execution conditions are abominable, and are dangerous, pollution is arranged, harm operating personnel health also has the rubber series product of employing or other macromolecular material both at home and abroad as top-grade building thing water-proof material, lacks because of raw material again, the price height is difficult to popularize and uses.
The object of the present invention is to provide a kind of film pliable and tough, the unit elongation height, physical and chemical performance is good, raw material sources are easy, construction costs is cheap, construction safety is building marine glue easily.
The technological process of production of the present invention as shown in the figure.
Below in conjunction with accompanying drawing production technique of the present invention is elaborated.
This building marine glue is to be main raw material with polyvinyl alcohol, formaldehyde, makes finished product through operations such as dissolving, condensation reaction, building-up reactions, adding assistant modification, additive aftertreatments.
The raw material ratio of this building marine glue is: polyvinyl alcohol 40%, formaldehyde 35.3%(divide input 3 times), phenol 12%, urea 7%, trimeric cyanamide 2%, acetic acid 1.9%, urotropine 1.8%, zinc oxide trace.
Polyvinyl alcohol is dissolved in 8 times the water under the situation of heating, maintains 90 ℃ of stirrings and boils to molten entirely.Add appropriate hydrochloric acid and transfer PH=1.5～2, inject 15% formaldehyde (accounting for total charging capacity) lentamente with the thread mode, keeps 70～90 ℃ to react hour, odd test viscosity reaches 220 seconds/normal temperature, promptly closes vapour and lowers the temperature.
After adding alkali lye and transferring PH=7～8, drop into phenol, zinc oxide, and inject 17.3% formaldehyde (accounting for total charging capacity) according to last method, be warming up to 70～95 ℃, insulation reaction 1.5 hours when being cooled to 70 ℃ then, adds 3% formaldehyde.
Under 70～80 ℃ of temperature, dropped into urea reaction 1 hour, add trimeric cyanamide reaction half an hour, add acetic acid reaction half an hour again.
The limit is stirred the cooling limit and is added liquid caustic soda and transfer PH=6, when treating that temperature is reduced to 40～50 ℃, successively adds urotropine, ammoniacal liquor, eliminating free aldehyde stink, and transfers PH=7～7.5.When temperature is reduced to room temperature (30 ℃), get final product discharging, obtain light brown or orange mobile colloid finished product.
This building marine glue is nontoxic, odorless, free from environmental pollution; Water-soluble, cold construction, easy construction, not only convenient but also safety; Physical and chemical performance is superior, and is weather-proof, ageing-resistant, and glue can be made into waterproof roll, also can make coating and use, and can mix use with sand-cement slurry, smears, builds by laying bricks or stones, and also desirable glass cloth is carrier application Waterproof glue line, good water-proof effect, and the usage period is long.Produce down because of normal temperature and pressure conditions, equipment is simple, operates uncomplicatedly, and raw material sources are easy, and are cheap, are easy to promote the popularization use.
Embodiment:
Add 544 kg of water in reactor, logical then being steam heated to about 60 ℃ dropped into 68 kilograms of polyvinyl alcohol, start stirring, boil whole dissolvings, add small amount of hydrochloric acid and transfer PH=1.5～2 at 90 ℃, inject 25 kilograms in formaldehyde lentamente with the thread mode, keep 90 ℃ of reactions 2 hours, observe the solution situation, odd test viscosity, as reach 220 seconds/normal temperature, pass vapour cooling adds liquid caustic soda and transfers PH=7～8, drops into 20 kilograms of phenol again, 0.01 kilogram in zinc oxide, and according to 30 kilograms in last method injection formaldehyde, logical steam slowly is warming up to 90 ℃, keeps thermotonus 1.5 hours, odd test viscosity, when reaching 230 seconds, be cooled to 70 ℃, add 5 kilograms in formaldehyde again.
Cast 12 kilograms in urea,, add 3.4 kilograms of trimeric cyanamides, reaction half an hour, close the vapour cooling after adding 3.2 kilograms of reactions of acetic acid half an hour again 70 ℃ of down reactions 1 hour.Afterwards, add liquid caustic soda and transfer PH=6, stir cooling simultaneously, when treating that temperature is reduced to 40～50 ℃, successively add 3 kilograms of urotropines, 10 kilograms of industrial ammonias, and transfer PH=7～7.5.When temperature is reduced to 30 ℃, get final product discharging, packing.(this moment, viscosity should reach 240 seconds/normal temperature)
