Problems solved by technology

This method is convenient for construction, but there are problems such as poor heat insulation effect, low reflection effect after falling dust, and long-term exposure to the outside, which will lead to aging and cracking of materials and short service life;
[0007] (4) Rigid waterproof and heat-insulating layer: It is generally composed of cement mortar, waterproof powder, perlite and other materials mixed with multiple layers, but it is rarely used because of easy cracking and poor heat insulation and waterproof effect

Abstract

The invention provides a waterproof reinforcing agent, waterproof foamed concrete and a roof waterproof system. The roof waterproof system comprises a roof structural layer and a waterproof foamed concrete layer arranged on the roof structural layer; and the waterproof foamed concrete layer is formed by the waterproof foamed concrete. Compared with the prior art, the waterproof reinforcing agent is adopted to modify foamed concrete to ensure that the structure of the waterproof foamed concrete is more uniform and stable to form a round and closed disconnected pore structure, the pore diameter is relatively small, hydrophobicity is generated, a relatively high waterproof effect is achieved, and the waterproof foamed concrete also has a relatively good heat insulation effect, so that the roof waterproof system not only has a relatively good waterproof effect but also has a relatively good heat insulation effect; moreover, the waterproof system provided by the invention has an integrated structure, is simple and convenient to construct, is relatively low in cost, is convenient to maintain, is lightweight, and is good in structural stability and long in service life.

Description

technical field [0001] The invention relates to the field of waterproof technology, in particular to a waterproof enhancer, waterproof foam concrete and a roof waterproof system. Background technique [0002] At present, low-carbon energy conservation has become a global sustainable development strategy, and building energy conservation is the key to urban energy conservation, accounting for the largest proportion of GDP in economic development, and all countries attach great importance to it. In building energy saving, because the roof is directly exposed to the sun, the heat insulation effect of the cement frame layer is not good. Therefore, the heat insulation and energy saving of the roof is very important, and scientific and effective methods must be adopted to solve it. In addition, the waterproofing of building roofs is also an essential and key issue that needs to be addressed in construction projects. Especially in tropical island areas, there are many typhoons and ...
