Problems solved by technology

Waterproof membranes are usually used for waterproofing. Waterproof membranes are prone to brittleness and aging after four seasons, resulting in leakage, especially for roof planting and greening. Plant roots can easily penetrate the waterproof layer, and the life of the membrane is short.

Embodiment Construction

[0016] Raw material name

[0017] Its processing and production process is to pour all the materials into the dispersion tank according to the proportion (remove the color paste part), disperse the materials evenly with a disperser, add the color paste and continue to disperse until uniform, then it can be discharged and packaged. The products prepared in the above examples have high strength, plant puncture resistance, aging resistance, energy saving, environmental protection, can be used outdoors for more than 30 years, save expensive maintenance costs, can add color and adjust colors arbitrarily, one investment, long-term benefit. Moreover, spraying polyurea waterproofing is the only long-term protection system in the domestic waterproof and thermal insulation system in the future, which provides a strong technical guarantee for solving some difficult waterproof projects. The measured technical parameters are: solid content 100%, gel time 10 seconds, tensile stre...

Abstract

The invention relates to a polyurea elastic body architectural engineering water-proofing material, which is constituted of component A and component B of equal weight ratio. The component A is isocyanate, component B includes raw materials (by weight ratio of component B) of: amido end-sealing epoxy alkane compound of 55-70%, diethyl toluenediamine of 8-10%, 3,3'-diethyl-4,4'-diaminodiphenylmethane of 3-5%, phosphite triester of 5-7%, dihexandiol ester of 3-5%, N,N'-dialkyldiamine of 5-8%, N,N'-dialkylmethanediamine of 2-4%, and titanium dioxide of 4-6%. Advantages of the invention are: high strength, plant puncture resistant, aging resistant, energy-saving, environmental protection, long using lifetime of more than 30 years, and changeable colors.

Description

technical field [0001] The invention relates to the field of polymer chemical materials used in construction engineering waterproofing, in particular to a polyurea elastomer construction engineering waterproofing material. Background technique [0002] Roof waterproofing of existing buildings, industrial plants, cold storage vapor barriers, reservoirs, bridges, tunnels, underground engineering, cooling towers of power plants, sewage treatment pools, aquariums, swimming pool linings and other fields. Waterproof membranes are usually used for waterproofing. Waterproof membranes are prone to brittleness and aging through the alternation of seasons, resulting in leakage, especially for roof planting and greening. Plant roots can easily penetrate the waterproof layer, and the life of the membrane is short. Contents of the invention [0003] The purpose of the present invention is to provide a polyurea elastomer construction engineering waterproof material with reasonable materi...
