Abstract

The invention discloses an environment-friendly heat-insulating and flame-retardant PBT waterproof and seepage-proof coiled material which is characterized by being prepared from the following raw materials in parts by weight: 55-65 parts of PBT resin, 15-25 parts of sulfonated SBS, 10-15 parts of 2, 4-diamino-6-diallylamino-1, 3, 5-triazine / 2, 5-bis (1, 2, 4-triazole-1-yl) terephthalic acid polycondensate, 3-5 parts of tetrakis (3-mercaptopropionic acid) pentaerythritol ester, 8-13 parts of modified POSS, 2-4 parts of phosphorus pentoxide, 1-2 parts of an initiator, 1-3 parts of an antioxidant and 0.5-0.8 parts of a foaming agent. The invention also discloses a production process of the environment-friendly heat-insulating and flame-retardant PBT waterproof and seepage-proof coiled material. The environment-friendly heat-insulating and flame-retardant PBT waterproof and seepage-proof coiled material disclosed by the invention is remarkable in waterproof and seepage-proof effect, excellent in heat insulation and heat preservation properties, flame retardance and environmental protection property, good in weather resistance and heat resistance, high in tear resistance and tensile strength and excellent in performance stability.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to an environmentally friendly, heat-insulating and flame-retardant PBT waterproof and anti-seepage coiled material and a production process 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. The problem of water seepage and water leakage in buildings has seriously affected people's normal life and has great potential safety hazards. In order to resist the infiltration of external rainwater and groundwater, waterproof and anti-seepage membranes have emerged as the times require. They are highly expected by people and play a vital role in building waterproofing projects. [0003] Waterpr...

Problems solved by technology

[0004]At present, the most widely used waterproof and anti-seepage membrane at home and abroad is modified asphalt membrane. This kind of material has good waterproof and anti-seepage effect, but its stripping The strength is low, and the waterproof performance is insufficient. With the prolongation of the use time, its waterproof performance will weaken, and it will pollute the environment, which will easily cause safety accidents; its construction speed is slow, and it is greatly affected by weather changes, base surface flatness and moisture content. Easy to delay the duration

Other types of waterproof and anti-seepage membranes on the market are generally expensive to prepare, and the viscosity, elongation at break, flame retardancy, heat insulation, environmental protection and high temperature resistance all need to be further improved.

[0005]Polybutylene terephthalate resin (PBT resin) belongs to the polyester series, which is 1,4-butanediol and terephthalic acid or terephthalic acid The milky white translucent to opaque, crystalline thermoplastic polyester material, which is condensed from dicarboxylic acid ester and produced through the mixing process, has excellent mechanical properties, outstanding chemical resistance, abrasion resistance, and Thermal and fatigue resistance, excellent electrical properties, better flexibility, wind resistance and water resistance, have high potential value in the field of waterproof and anti-seepage materials, but the notched impact strength of this material is low and the molding shrinkage High rate
