Problems solved by technology

[0002] The waterproof materials in the prior art include modified asphalt waterproof coatings. The use of various polymer modified asphalt can greatly improve the performance of asphalt substrates, but its disadvantages are also obvious: it is easy to crystallize at low temperatures, and if it is placed for a long time after construction It is easy to cure, so the original performance of the waterproof material cannot be maintained, which greatly limits the service life

Abstract

The invention discloses liquid butyl rubber asphalt waterproof coating and a preparation method. According to the invention, a used additive has long chain and low molecular weight, can ensure that the asphalt can be mutually mixed and dissolved with various high polymer materials in the production process, so that steady combination is formed, respective characteristics take effect under the most steady state in the application process, and thus the asphalt never can be cured. The preparation method of the waterproof coating disclosed by the invention comprises the following steps of heating the asphalt in formula weight to 130-180 DEG C, then, adding liquid butyl rubber, SBS, naphthenic oil and petroleum resin into the asphalt in formula weight, stirring at 175-180 DEG C for 1-2h, finally, decreasing the temperature to 160 DEG C, adding reclaimed rubber in formula weight, stirring for 1-1.5h till the mixture is uniform and does not contain particles, and discharging after the mixture is molten. The waterproof coating disclosed by the invention has the advantages that the waterproof coating is difficult to crystallize at low temperature; the waterproof coating cannot be cured even though placed for a long time after construction; the original property of the waterproof material is kept; and furthermore, the service life of the waterproof coating is greatly increased.

Description

technical field [0001] The invention relates to a liquid butyl rubber asphalt waterproof coating and a preparation method thereof. Background technique [0002] The waterproof materials in the prior art include modified asphalt waterproof coatings. The use of various polymer modified asphalt can greatly improve the performance of asphalt substrates, but its disadvantages are also obvious: it is easy to crystallize at low temperatures, and if it is placed for a long time after construction It is easy to cure, so the original performance of the waterproof material cannot be maintained, which greatly limits the service life. Contents of the invention [0003] In view of this, the main purpose of the present invention is to provide a kind of liquid butyl rubber asphalt waterproof coating and its preparation method, the additive used in it is long chain, low molecular weight, can make asphalt and various macromolecular materials intermix in the production process , miscible, f...
