Problems solved by technology

When the existing asphalt waterproofing membrane is in use, it is necessary to cover the top of the asphalt waterproofing membrane with mortar or fine stone concrete, or cover the top of the asphalt waterproofing membrane with shale flakes or sand grains for self-protection, so as to prevent the asphalt waterproofing membrane from The problem that the temperature of the coil is too high due to direct sunlight
[0003] However, the surface roughness of mortar, fine stone concrete, shale or sand grains is relatively large, and the reflection performance of sunlight is poor, so the heat insulation effect is also poor

Embodiment 1

[0038] The embodiment of the present invention provides an asphalt heat insulation and waterproof coiled material, such as figure 2 As shown, the asphalt heat-insulating and waterproofing membrane comprises from bottom to top: a first isolation membrane 1, a first asphalt layer 2, a base layer 3, a second asphalt layer 4, a first isolation membrane 5 and a reflective heat insulation layer 6 .

[0039] It can be seen that the asphalt heat insulation and waterproof membrane of the embodiment of the present invention adds a reflective heat insulation layer 6 on the surface of the existing asphalt waterproof membrane, and the new asphalt heat insulation and waterproof membrane not only has waterproof function, but also has the function of reflecting sunlight The function can achieve good heat insulation effect. Moreover, when the exterior wall or roof of the building has waterproof function and reflective heat insulation function at the same time, the required construction proce...

Embodiment 2

[0044] Embodiment 2 of the present invention provides a process for preparing an asphalt heat-insulating and waterproof membrane. The asphalt heat-insulating and waterproof membrane is subjected to traction during the entire preparation process, such as image 3 As shown, the preparation process of asphalt thermal insulation and waterproof membrane specifically includes the following steps:

[0045] Step S1, unfolding the base layer of the tire;

[0046] Step S2, making the base layer pass through the oil immersion tank at a constant speed to perform asphalt pre-impregnation;

[0047] Step S3, passing the pre-impregnated base layer through the oiling tank at a constant speed, performing a second asphalt impregnation, forming a first asphalt layer on the lower surface of the base base, and forming a second asphalt layer on the upper surface of the base base;

[0048] Step S4, forming a first isolation film on the side of the first asphalt layer away from the base layer, and fo...

Abstract

The invention provides an asphalt heat-insulating and waterproof coiled material and a preparation method thereof, which relate to the technical field of waterproof building materials and are used for reflecting sunlight to achieve a good heat-insulating effect. The asphalt heat-insulating and waterproof coiled material sequentially comprises: a first isolation membrane, a first asphalt layer, a base layer, a second asphalt layer, a second isolation membrane and a reflective heat-insulation layer from bottom to top. The preparation process of the asphalt heat-insulating and waterproof membrane includes: under the action of traction, the base layer is unfolded; the base layer is impregnated with asphalt, and the first asphalt layer and the second asphalt layer are respectively formed on the downward side and the upward side of the base layer. Form the first isolation film on the side of the first asphalt layer away from the base layer, and form the second isolation film on the side of the second asphalt layer away from the base layer; spray reflective heat-insulating paint on the surface of the second isolation film to form a reflective barrier Hot layer; drying and winding the sprayed asphalt strip. The invention can be used for wall or roof construction.

Description

technical field [0001] The application relates to the technical field of waterproof building materials, in particular to an asphalt heat-insulating waterproof coiled material and a preparation method thereof. Background technique [0002] Bituminous waterproof membranes are usually used to lay on the exterior walls or roofs of buildings, and have waterproof functions. When the existing asphalt waterproofing membrane is in use, it is necessary to cover the top of the asphalt waterproofing membrane with mortar or fine stone concrete, or cover the top of the asphalt waterproofing membrane with shale flakes or sand grains for self-protection, so as to prevent the asphalt waterproofing membrane from The problem that the coil temperature is too high due to direct sunlight. [0003] However, mortar, fine stone concrete, shale, or sand grains have a rougher surface and are less reflective of sunlight and thus less effective in insulating heat. Contents of the invention [0004] ...
