A solvent-free asphalt waterproofing material containing a modified silicon polymer comprises 15-20 parts by weight straight asphalt, 1-5 parts by weight thermoplastic rubber -5 parts by weight C9 aromatic petroleum resin, 3-8 parts by weight paraffinic white oil, 10-15 parts by weight petroleum hydrocarbon oil, 12-18 parts by weight modified silicon polymer, 30-50 parts by weight filler, 0.5-1.5 parts by weight dehydrating agent and 0.5-1.5 parts by weight adhesion accelerator

Description

technical field [0001] The invention relates to a cold-applied solvent-free asphalt coating waterproof material, in particular to an environmentally friendly cold-applied solvent-free asphalt coating waterproof material containing a modified organosilicon polymer and a manufacturing method thereof. The polymer component can prevent rapid oxidation and aging caused by high-temperature melting, suppress the generation of harmful gases during operation, and minimize environmental pollution while ensuring the safety of operators. Background technique [0002] Generally speaking, the so-called waterproofing compound (Waterproofing Compound) refers to the application of water-based or oil-based liquid waterproofing materials on the surfaces of various buildings and structural walls, and the waterproofing effect is obtained by using the film left after the water or solvent evaporates. of composite materials. [0003] This kind of film waterproof material is usually used for roof w...

AI Technical Summary

Problems solved by technology

[0007] As mentioned above, the rubber asphalt-based coating film waterproof material has the advantages of elongation, crack resistance, frost resistance and bonding, but also has poor reducing power, chemical resistance, ozone resistance and ultraviolet resistance. The problem

[0008] As far as the coating film waterproof material mainly composed of styrene-butadiene rubber (Styrene Butadiene Rubber; SBR) is concerned, due to its very poor reducing power, there is a problem that once it is repeatedly elongated, it will degenerate and lose its original physical properties. This will inevitably result in a loss of quality

[0009] In addition, for coating waterproof materials with SBR as the main component, due to their poor chemical resistance, ozone resistance and ultraviolet resistance, there is a problem that they are exposed to various chemicals and ozone for a long time, or exposed to ultraviolet rays. Quality also drops dramatically

[0010] On the contrary, as far as the coating film waterproof material mainly composed of chloroprene rubber (Chloroprene Rubber Latex; CR) is concerned, due to the poor freezing resistance (Freezing Resistance), there is a problem that it is difficult to actively respond to changes in the surrounding environment.

[0021] At this time, due to the improvement of the low temperature and poor flexibility of waterproof asphalt, the waterproof performance has been relatively improved, but its viscosity is higher than that of waterproof asphalt. In order to maintain a workable temperature, the on-site heating temperature is required to reach about 220 ° C. As mentioned above, there are still problems such as environmental pollution, damage to the physical properties of asphalt, weakening of waterproof performance, and there are safety hazards such as burns.
