1. What materials are used for outdoor waterproof materials?
Common waterproof materials are divided into four categories.
(1) Asphalt waterproof material:
Asphalt linoleum, paper tire asphalt linoleum, solvent-based and water-emulsion asphalt or asphalt rubber coatings and ointments with natural asphalt, petroleum asphalt and coal asphalt as main raw materials have good cohesiveness, plasticity, water resistance, corrosion resistance and durability.
② Rubber and plastic waterproof materials:
Using chloroprene rubber, butyl rubber, ethylene propylene diene monomer, polyvinyl chloride, polyisobutylene and polyurethane as raw materials, elastic tire-free waterproof coiled material, waterproof film, waterproof coating, ointment, putty, water stop and other coatings and sealing materials can be made. It has the characteristics of high tensile strength, high elasticity and elongation, good adhesion, good water resistance and weather resistance, can be used cold and has a long service life.
(3) Cement waterproof material:
Admixtures, such as waterproofing agent, air entraining agent and expansion agent, can accelerate the setting and compaction of cement and enhance the hydrophobicity and impermeability of cement mortar and concrete; Accelerated setting mortar based on cement and sodium silicate can be used for plugging and waterproofing in underground engineering.
(4) Metal waterproof material:
Thin steel sheet, galvanized steel sheet, profiled steel sheet and coated steel sheet can be directly used as roofing waterproof sheets. Steel plate is used as metal waterproof layer of basement or underground structure. Thin copper plate, thin aluminum plate and stainless steel plate can be made into water stop for deformation joints of buildings. Joints of metal waterproof layer shall be welded and painted with antirust protective paint.
At present, asphalt has been basically eliminated, and rubber and plastic waterproof materials, such as SBS waterproofing membrane, are mostly used for outdoor waterproofing, which has excellent waterproof performance and will volatilize toxic gases; Cement waterproof materials are mostly used for waterproofing in kitchens and bathrooms because of environmental protection, while metal waterproof materials are less used because of their high cost.
Second, the outdoor waterproof material brand recommendation
1, Yu Hong
First of all, the outdoor waterproof material introduced to you is rain rainbow waterproof. Beijing Oriental Yuhong Waterproof Technology Co., Ltd. is committed to the exploration and research of systematically solving waterproof problems. Now, it has become a leading enterprise in waterproof industry integrating research and development, production, sales and construction services of waterproof materials, and is the first listed company in China waterproof industry. The company has a world-class multifunctional production line of imported modified asphalt waterproofing membrane, cold self-adhesive asphalt waterproofing membrane and environmental protection waterproof coating.
2. Keshun-Reid
The outdoor waterproof material that I will introduce to you next is Keshun-Ylaide. Guangdong Keshun Chemical Co., Ltd. is a national high-tech enterprise specializing in research and development, manufacturing, product marketing, technical consultation and waterproof construction of building waterproof materials, and produces three series of products of "CKS Keshun" brand building waterproof coiled materials, building waterproof coatings and drainage protection plates. The company has participated in the professional committee of waterproof materials of China Silicate Society, and is one of the largest professional manufacturers of waterproof materials in China.
The above recommendation is about the matters needing attention in the selection and purchase of outdoor waterproof materials, from which we can know that it is different from indoor waterproof coatings. Outdoor building materials have relatively strict requirements on the performance of the products themselves. They can withstand the wind and rain and will not be damaged by corrosion after long-term use. Moreover, they can not only protect outdoor wall tiles, floor tiles and other ground decoration building materials, but also play a decorative and beautiful role. Appropriate and reasonable customization can be made according to actual demand and budget. I believe that this will achieve a satisfactory final practical effect.
