What is the difference between construction non-vulcanized waterproofing membrane and vulcanized waterproofing membrane?
The advantages of the present invention Is: 1. elongation of permanent deformation is good, after stretching the rebound rate is small, no internal stress, can be fully adapted to the external factors caused by the deformation, there is no accelerated aging after the problem, so the service life can be improved 2-3 Times more than. 2. elongation, up to 1000%. 3. Natural vulcanization of a long time, can reach more than 10 years. 4. Good resistance to low temperature performance. 5. Bonding performance is good. 6. Production costs and operating costs are lower than other existing products.
The vulcanized waterproofing membrane is characterized in that it consists of a vulcanized butyl rubber, a softening agent, a hard acid and a filler, wherein the parts by weight are butyl rubber: softening agent: hard acid: filler = 1 : 0.003-0.015: 0.006-0.036: 0.32-0.73, wherein the softening agent uses a mechanical oil, which can also be made into a high-strength waterproofing membrane by sandwiching a layer of the web between the two layers of the waterproofing membrane.
Non-vulcanized rubber waterproofing membrane: from SR or SR and asphalt blends by mixing, rolling made of coil, without vulcanization can use the product. The bonding between the coils and their bonding properties with the mortar is good, the manufacturing is convenient, the price is low, but the tensile strength is low. Can be divided into two types of rubber and rubber asphalt. Rubber type commonly used SBR and other SR production. Generally used for civil construction roof waterproof.
