Description
Technical field
The present invention relates to a kind of water-repellent paint, particularly to the spraying rapid hardening water-repellent paint of a kind of applicable severe cold area application.
Background technology
Spraying rapid hardening rubber asphalt waterproof coating main component is made up of two or more high-performance modified emulsified rubber asphalts and chemistry coagulant catalyst, has the two-component system of rapid initial set consolidation behavior. It is a kind of employing mechanically spraying construction technology, can make the small molecule micelle in material rapidly and concrete cement basic unit forms sucker effect, blocking basal plane pore firm film forming, there is the glued membrane system product of excellent waterproof, anticorrosion, barrier propterty.
Spraying rapid hardening rubber asphalt waterproof coating is except the advantage with conventional waterproof coating, also have characteristics that 1) spray the domestic water-repellent paint that rapid hardening rubber asphalt product is employing cold-working industry spraying application new technology, construct simple, quick and easy, the duration is short, effect improves, and unit rush-harvesting and rush-planting (3 people's group) 8h continuous spray (thickness 2mm) area is at 1000m2; 2) this product is composited by ipn technology and nanotechnology and asphalt modification by multiple compounded rubber, utilizes coagulant Catalysis Principles to make the rapid initial set of product, and film forming speed is fast, and initial set is only 3～5s hardening time; 3) one-pass film-forming in coating film thickness 1～4mm can be accomplished, save time, laborsaving, efficient, and keep the uniformity that glued membrane is good; 4) this product is to on-the-spot strong adaptability, and basic level requirement is wide in range, and execution conditions are not harsh, is suitable for various special-shaped basal planes, only need substrate surface clean, without open fire; Only need basic unit is carried out simple smooth process before construction, generally need not separately do screed-coat; 5) there is higher elasticity and puncture resistance after formed product, fracture elongation 1200%～1800%, and there is the self-healing function of excellence; 6) having excellent heat-resistant stability and low temperature resistivity, applied environment temperature is-35～80 DEG C; 7) glued membrane and multiple basic unit (except resinae, nickeliferous, containing chronium metal, containing oils) and water-repellent paint between to have good caking property, aging resistance and corrosion resistance strong;8) this product fire protection flame retarding, from fire self-extinguishment, combustibility meets safe construction requirement; 9) product is water base, and VOC content is low, nontoxic, tasteless and nonirritant, production, work progress Non-carbonized, the flames of anger, pollution-free, environmental protection, convenient transportation. Due to above-mentioned plurality of advantages, spraying rapid hardening rubber asphalt series waterproofing paint is widely used, and can be used for building and underground project waterproof, industrial building and hardware is antiseptic and rustproof, concrete and brick setting protection, Treatment Measures to Leakage and reparation, large pool, gas tank, garbage disposal plant, sewage treatment plant's waterproof protective etc.
