Description

TECHNICAL FIELD

[0001] The utility model relates to house building technical field, concretely relates to a RX hydrophobic resin emulsified asphalt expanded perlite heat preservation anti -infiltration composite mastic mat. BACKGROUND

[0002] House building refers to the entity that provides users or investors with living, production, work or other activities at the planning and design site. Building roof is the surface of building roof, and building roof needs to have the functions of wind-shielding, rain-shielding, heat preservation, heat insulation, structure protection, load bearing, fire prevention, ventilation, and anti-infiltration and waterproofing.

[0003] Mastic mat is a material made of high-strength adhesive and high-quality rubber, which has excellent cushioning, sound insulation and shock absorption capabilities. It is commonly used for vibration isolation and shock absorption of various mechanical equipment, buildings and roads. Building roof usually uses mastic mat to (1) enhance waterproof effect: mastic mat not only has certain waterproof performance itself, but also can form better adhesion with subsequent waterproof materials, thereby improving the effect of the entire waterproof system. Mastic mat can ensure that the waterproof material is laid more tightly, reducing the risk of leakage. (2) Protect the internal structure: through the laying of mastic mat, an additional layer of protection can be formed for the internal structure of the roof. This layer of protection can reduce the influence of external environment on the internal structure, such as rainwater penetration, temperature change, etc., thereby prolonging the service life of the roof. (3) Improve construction efficiency and quality: using mastic mat for leveling can greatly improve the construction efficiency. The leveled roof is more flat, making the building surface flat and beautiful, and making subsequent construction more convenient, so that the waterproof material can be laid faster and more accurately. At the same time, the existence of mastic mat can also improve the overall construction quality, ensuring the waterproof performance and durability of the roof, which can effectively seal gaps and cracks.
