Heat-insulating, anti-freezing and waterproof roll material and preparation method

Abstract

The invention discloses a heat-insulating, anti-freezing and waterproof coiled material and a preparation method thereof, belonging to the technical field of waterproof coiled materials. The heat-insulating, anti-freezing and waterproof coiled material includes a base material layer of glass fiber felt, and also includes a heat-insulating layer arranged on the upper surface of the glass fiber felt, and the glass fiber felt and the heat-insulating layer are connected by an adhesive layer, The upper surface of the heat insulation layer is provided with a first waterproof layer, the upper surface of the first waterproof layer is provided with a heat insulation coating, and the lower surface of the glass fiber felt layer is also provided with a second waterproof layer, and the second waterproof layer A protective layer is provided on the lower surface of the layer. The heat-insulating, anti-freezing and waterproofing membrane material of the present invention not only has a good waterproof effect, but also has an excellent heat-insulating and anti-freezing effect, can greatly reduce the temperature exchange inside and outside the building, and reduce energy consumption. In addition, the preparation method is simple and easy, It has good application value.

Description

technical field [0001] The invention relates to the technical field of waterproof coiled material, in particular to a heat-insulating, antifreeze and waterproof coiled material and a preparation method thereof. Background technique [0002] Waterproof membrane is mainly used in building walls, roofs, tunnels, roads, landfills, etc., to resist external rainwater and groundwater leakage, a flexible building material product that can be rolled into rolls, as an engineering basis The leak-free connection with the building is the first barrier for the waterproofing of the entire project and plays a vital role in the entire project. The main products are asphalt waterproof membrane and polymer waterproof membrane. At present, the use of coiled materials mainly reflects the waterproof performance. If the material is not only waterproof, but also heat-insulating, this will cause the material to be too heavy to be used in many buildings, such as roofing materials. Simultaneously pr...

AI Technical Summary

Problems solved by technology

However, the current waterproof membrane cannot effectively improve the internal and external heat insulation effect of the building and save better resources.

Various existing building waterproofing membranes have different defects, such as: (1) Asphalt membranes and modified asphalt linoleum are easy to melt and flow at high temperatures and brittle at low temperatures, so that the waterproof effect is not good , especially the linoleum cannot withstand multiple folds during handling and construction, resulting in cracking and water leakage

(2) Although the materials of EPDM and chlorinated polyethylene waterproofing membranes are good, they are expensive

(3) PVC coils have disadvantages such as poor anti-aging performance, low tensile strength, and easy generation of air bubbles, which directly affect the service life or waterproof effect

(4) The common disadvantages of existing waterproof membranes are that the heat insulation effect is poor, and the construction process is troublesome, such as the need for construction machinery and tools, and the need to burn firewood to supply energy for heating, etc.

There is also a practice of using the foam board as an insulation layer and laying waterproof membranes on or under it, but the waterproof membrane is prone to aging due to sunlight and has a short service life; the foam board is easy to absorb water when it is placed on the waterproof membrane swelling, loss of insulation
