Description

Technical Field

[0001] The utility model relates to the technical field of glass fiber felt, in particular to an alkali-resistant glass fiber felt. Background Art

[0002] Glass fiber has a wide range of uses in transportation, industry, construction, environment and other fields. Glass fiber mat is a thin sheet product made by combining continuous strands or chopped strands in an undirected manner through chemical binders or mechanical action. Glass wool roll mat is a thermal insulation material widely used in construction, automobiles, aerospace and other fields. It is made of high-purity glass fiber as raw material and has excellent thermal insulation and fireproof properties. It is widely welcomed by the market; glass fiber mat has good alkali resistance and can have high corrosion resistance in cement and other media, so it can be used to reinforce cement, gypsum (RPG) and other non- Organic materials, in addition, alkali-free glass fiber itself has good chemical stability, so alkali-free glass fiber needle felt also has good alkali resistance. After experiments and application verification, the material has excellent performance in neutral and weak alkaline environments, and can withstand long-term immersion in aqueous solutions with a pH value of 6 to 8 without obvious damage; however, glass fiber felt, as a thermal insulation material during the construction process, will directly contact with cement, and cement has a strong alkalinity. The direct contact between the two is likely to cause certain effects on the glass fiber felt, and cause it to corrode and damage during subsequent use. To this end, we propose an alkali-resistant glass fiber felt. Utility Model Content

[0003] In view of the problems in the prior art, the utility model provides an alkali-resistant glass fiber felt.

[0005] By adopting the above technical solution, when glass fiber felt is used in the construction process, the rock wool layer on the periphery of the glass fiber body can directly block the glass fiber body, so that the cement will not come into contact with it, and the glass fiber felt can also provide good thermal insulation performance. At the same time, the hydrophobic layer coated on the periphery of the rock wool layer can improve the hydrophobicity when the cement and the rock wool layer are in contact, and in combination with the aluminum foil layer, the rock wool layer and the glass fiber body can stably provide thermal insulation and fire protection functions during the construction process, so that the glass fiber felt can operate stably.

[0006] Specifically, a glass fiber mesh layer is sewn and installed between the rock wool layer and the glass fiber body.

[0007] By adopting the above technical solution, the glass fiber mesh layer can improve the tightness of the rock wool layer and the glass fiber body after being connected, so that the two can form a whole for use.

[0008] Specifically, a sponge layer is integrally constructed on one side of the aluminum foil layer close to the rock wool layer.

[0009] By adopting the above technical solution, the sponge layer has certain heat preservation and elasticity, which is convenient for supporting the aluminum foil layer, so that the aluminum foil layer can operate stably.

[0010] Specifically, the rock wool layer, the hydrophobic layer, the sponge layer and the aluminum foil layer are evenly distributed on the periphery of the glass fiber body.

[0011] By adopting the above technical solution, the rock wool layer, hydrophobic layer, sponge layer and aluminum foil layer distributed in sequence can work together, so that the glass fiber body can operate more safely and stably.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] The technical solution of the present application is designed with a rock wool layer, a hydrophobic layer and an aluminum foil layer. When the glass fiber felt is used in the construction process, the rock wool layer on the periphery of the glass fiber body can directly block the glass fiber body, so that the cement will not come into contact with it, and the glass fiber felt can also provide good thermal insulation performance. At the same time, the hydrophobic layer coated on the periphery of the rock wool layer can improve the hydrophobicity when the cement and the rock wool layer are in contact. In combination with the aluminum foil layer, the rock wool layer and the glass fiber body can stably provide thermal insulation and fire protection functions during the construction process, so that the glass fiber felt can operate stably.
