AI Technical Summary

Problems solved by technology

[0002] At present, the surface layer of ordinary waterproof materials has limited resistance to environmental aging and corrosion resistance, resulting in problems such as low service life of waterproof membranes, unsatisfactory waterproof and wear resistance, etc.
Mortar protective layer must be used in construction to prevent puncture damage and ultraviolet damage, and cannot withstand the corrosion of acid, alkali, and chlorine corrosives in water, resulting in premature leakage
[0003] The existing self-adhesive polymer waterproofing membranes for weather-resistant roofs have the following main defects: (1) The existing self-adhesive polymer waterproofing membranes for weather-resistant roofs have low impermeability, low low temperature resistance and stability Not high, not suitable for areas with high cold in the northwest and large temperature difference between day and night;
[0004] (2) The existing self-adhesive polymer waterproof membrane for roofing with good weather resistance has low wear resistance and tear resistance

Abstract

The invention provides a good-weatherability self-adhesive polymeric waterproof coiled material for a roof. The waterproof coiled material comprises acrylate rubber, polysulfide rubber, a viscosity reducer, talcum powder, nano-TiO2, polyglycerol polyricinoleate, sodium alginate and nonoxynol-9, wherein a Pt-Co chromaticity of the viscosity reducer is not higher than 20, the moisture content of theviscosity reducer is not higher than 1.0%, a pH value of a 1% aqueous solution of the viscosity reducer is 6.0 to 7.5, and an HLB value of the viscosity reducer is 15 to 16. A preparation method forthe waterproof coiled material comprises microwave treatment, wherein a first microwave power density is 3 kW / m<3> to 5 kW / m<3>, and the time is 40 to 45 minutes; and a second microwave power densityis 0.5 kW / m<3> to 1.5 kW / m<3>, and the time is 5 to 7 hours. According to the good-weatherability self-adhesive polymeric waterproof coiled material for the roof and the preparation method for the good-weatherability self-adhesive polymeric waterproof coiled material, the low-temperature resistance of the waterproof coiled material is improved, and thus, an adaptative minimum temperature range ofthe waterproof coiled material is -26 DEG C to -21 DEG C; and the waterproof coiled material has the advantages of high imperviousness, good low-temperature resistance, high thermal aging performanceand high stability, and therefore the coiled material is particularly adaptable to Northwest districts which are high cold and are large in diurnal temperature difference.
