preparation example Construction

[0033] A preparation method of a waterproof coiled material, comprising the steps of:

[0034] A. In terms of parts by mass, take 100# asphalt and heat it up to 170~180°C and mix for 30~50 minutes, add 10# asphalt with 20~50% of the quality of 100# asphalt, stir and mix for 20~30 minutes, then add 100# asphalt 20~40% of the elastomer additive, stirred and mixed at 100~120°C for 1~3h to obtain the matrix;

[0035] B. According to the mass fraction, take 8~12 parts of modifier, 5~8 parts of anti-ultraviolet absorption additive, 1~4 parts of antioxidant, 20~30 parts of talcum powder, and stir and mix at 75~80°C for 1~3h , to obtain mixture b, take mixture b according to the mass ratio of 3~5:10~30, add the matrix and mix, stir and mix at 170~180°C for 40~50min, and obtain impregnating solution, take polyester felt and immerse in the impregnating solution, keep for 3~5min , take out the impregnated polyester felt, press it, and dry it to obtain the anti-coil material.

Abstract

The invention discloses a waterproof roll and a preparation method thereof and belongs to the technical field of building waterproof materials. According to the waterproof roll, polytetramethylene ether ethylene glycol and polycaprolactone are compounded to form a polyhydric alcohol system, then a polyurethane high polymer with elasticity can be formed, the strength and the adhesion of asphalt canbe improved, buffering can be achieved, and the wearing resistance of the roll can be improved; trimellitic anhydride and diisopropanol are adopted as raw materials for an esterification reaction, asphalt molecules can be immobilized in a three-dimensional structure, the capability of preventing foreign matter embedding can be improved, and the waterproof performance can be improved; due to addition of magnesium nitrate, aluminum nitrate and urea, oxidization reaction inhibition and neutralization are implemented, a synergetic effect is achieved, chloridion invasion can be prevented, corrosion can be reduced, and a good protection function on aging resistance of the waterproof roll is achieved. By adopting the waterproof roll, the problems that a conventional waterproof roll is poor in weather resistance, aging resistance and mechanical property can be solved.

Description

technical field [0001] The invention belongs to the technical field of building waterproof materials, and in particular relates to a waterproof coiled material and a preparation method thereof. Background technique [0002] With the development of the economy and the progress of the times, the requirements for building materials are getting higher and higher, and the original building materials can no longer meet the needs of the development of the times. Many buildings have lost their useful life due to water erosion. As people's requirements for the service life of buildings are getting higher and higher, people's requirements for the quality of waterproof materials are becoming more and more important. Waterproof membrane is a kind of building material commonly used in building construction. In the construction of road bridges, roofs or buildings that need waterproofing, waterproof membranes need to be laid in advance. In the production process of the waterproof membran...
