Abstract

The present invention relates to a water-proof paint capable of resisting both high-temp. and low-temp. and its preparation method. It is made up by proportioning solid asphaltic bitumen, rosin, vegetable oil and no.120 solvent oil according to its formula, and its preparation method is as follows: the asphaltic bitumen is heated and diluted, and then cooled, and the rosin and vegetable oil are respectively heated, and then they are mixed, and then the above-mentioned all materials are fully stirred and uniformly mixed, so that the invented product can be made up. Said invention solves the problems of water-proofing and dampproofing for building roof, cellar and toilet, and anti-corrosion and rust protection of water and petroleum pipeline.

Description

High-temp. and low-temp.-resisting water-proof paint and its preparation method

The present invention relates to a kind of building coating, waterproof, moistureproof, anticorrosion, antirust--high-and low-temperature resistance waterproof paint and manufacture method thereof.

At present, normal waterproof, the moisture-proof coating that uses has pitch and PVC coating etc. in building field both at home and abroad, when building is used in the winter time, pitch can ftracture, and when summer temp is high, can melt trickling, influence construction quality, a large amount of smog that produce during the pitch cast, contaminate environment.

The purpose of this invention is to provide a kind of novel, construction waterproof coating and manufacture method thereof strong adhesion, that water resistance is good, this coating does not use at normal temperatures and need heat, smokeless and dust free is free from environmental pollution, can be high temperature resistant and low temperature resistant.

High-and low-temperature resistance waterproof paint of the present invention and manufacture method content Description thereof:

High-and low-temperature resistance waterproof paint of the present invention and manufacture method thereof is characterized in that: the formula rate of coating is: asphalt content is 40～60%, content of vegetable oil is 0.5～2.0%, rosin 1.5～3.0%, 120# solvent oil 30～40%; Its manufacture method is:

1, solid bitumen is put into the container of heating, be heated to 120～200 ℃, fully pitch is cooled to 100～140 ℃ again after the dilution;

2, rosin is heated in the still of heating to 250～280 ℃, add vegetables oil again and continued to heat 1～3 hour, be heated to 280～320 ℃, fully stir and be cooled to 200～240 ℃;

3, the mixture of rosin and vegetables oil is poured into fully stirring in the cooled pitch of dilution, added the 120# solvent oil again and stir;

4, sealing is packaged in the solution that stirs after mixing in the container tank;

Making solution is the black viscous liquid.

High-and low-temperature resistance waterproof paint of the present invention has solved phenomenons such as winter building construction roof cracking, building operation roof trickling in summer, and waterproof, humidity resistance are good, can be used for the top of building and vault, toilet warterproof, protection against the tide; Be used for water delivery, oil pipeline is antiseptic and rustproof.Do not trickle in 50 ℃ of uses above freezing, subzero 40 ℃ of uses are not ftractureed, waterproof paint strong adhesion water-tolerant of the present invention, non-environmental-pollution.

Embodiment:

When producing 1000kg high-and low-temperature resistance waterproof paint, get solid bitumen 600kg, put into the container of heating, heating, temperature reaches 180 ℃ of pitches and fully dilutes, and pitch is cooled to 130 ℃; Get rosin 26kg heating still internal heating temperature to 260 ℃, add soya-bean oil 11kg again, continued to heat 2 hours, temperature rises to 280 ℃, fully mixes; The mixture of cooled fluxed asphalt and rosin, soya-bean oil is mixed, adds the 120# solvent oil of 363kg after stirring again, stir, promptly make the black viscous liquid--the high-and low-temperature resistance waterproof paint.The sealing tinning is preserved.

Claims

1, a kind of high-and low-temperature resistance waterproof paint and manufacture method thereof is characterized in that the formula rate of said coating is: asphalt content is 40～60%, content of vegetable oil is 0.5～2.0%, rosin content is 1.5～3.0%, 120# solvent oil content 30～40%; Its manufacture method is:

(1), solid bitumen is put into the container of heating, be heated to 120～200 ℃, fully pitch be cooled to 100～140 ℃ again after the dilution;

(2), rosin is heated in the still of heating to 250～280 ℃, add vegetables oil again and continued to heat 1～3 hour, be heated to 280～320 ℃, fully stir and be cooled to 200～240 ℃;

(3), the mixture of rosin and vegetables oil poured in the cooled pitch of dilution fully stirs, add the 120# solvent oil again and stir;

(4), sealing, the solution that stirs after mixing is packaged in the container tank;

The high-and low-temperature resistance waterproof paint that makes is the black viscous liquid.
