Manufacture method of elastomer modified asphalt waterproof coiled materials

Abstract

The invention relates to a manufacture method of elastomer modified asphalt waterproof coiled materials. A waterproof coiled material sand spreading device is adopted for the manufacture method of the elastomer modified asphalt waterproof coiled materials and comprises a bottom plate, side vertical plates, a sand box, a top cover and a shaking mechanism. The manufacture method, achieved through the waterproof coiled material sand spreading device, of the elastomer modified asphalt waterproof coiled materials comprises the following steps that S1, modified asphalt blending is conducted; S2, coiled material blank dip-coating is conducted; S3, the coiled material sand spreading amount is regulated; and S4, sand spreading and film covering are conducted on the coiled materials. The problems that when existing waterproof coiled materials are subjected to the sand spreading action, the sand spreading amounts of the waterproof coiled materials are not uniform, the heights of sand on the waterproof coiled materials are not uniform, leakage holes are frequently blocked during spreading of a leakage frame, and therefore screen holes of the leakage frame need to be manually dredged, the sand spreading amount of the waterproof coiled materials cannot be adjusted, and the leaking frame can spread fine sand to the outer sides of blank bodies can be solved.

Description

technical field [0001] The invention relates to the field of waterproof coiled material processing, in particular to a method for preparing an elastomer-modified asphalt waterproof coiled material. Background technique [0002] Elastomer-modified asphalt waterproofing membrane uses thermoplastic elastomer as a modifier, and the modified petroleum asphalt is used as an impregnated coating material. Elastomer-modified asphalt waterproofing membrane uses glass fiber felt or polyester felt as a matrix, making the membrane a flexible and rollable sheet waterproof material, with good high and low temperature resistance and aging resistance, and easy construction Etc. [0003] After the elastomer-modified asphalt waterproofing membrane is dip-coated and spread evenly, a film will be attached to the lower side of the membrane matrix, and a layer of fine sand will be sprinkled on the upper side of the membrane matrix to prevent the waterproofing membrane from winding up. The phenom...

AI Technical Summary

Problems solved by technology

[0004] The amount of sand sprinkled on the waterproof membrane is not uniform, so that the height of the sand on the waterproof membrane is different, and the leakage frame often blocks the leak hole when spreading, so it is necessary to manually dredge the screen holes of the leakage frame, and the waterproof membrane The amount of sand sprinkling cannot be adjusted, and the leak frame will spread the fine sand to the outside of the carcass
