Description

Technical Field

[0001] The utility model relates to the technical field of coating felts, in particular to a glass fiber cement coating felt which is convenient for firmly combining with cement. Background Art

[0002] Glass fiber cement coating felt is a functional material specially used for the surface of exterior wall insulation board. It uses reinforced glass fiber felt as the base and undergoes a coating process. The coating amount is reduced by 3 times compared with the traditional spreading amount, thus achieving performance that ordinary cement mortar spreading products cannot achieve.

[0003] A glass fiber cement coating felt that is easy to combine firmly with cement is currently used. After searching, it is found that, for example, a Chinese patent document with the authorization publication number CN207646920U discloses a glass fiber cement coating felt that is easy to combine firmly with cement, including a base layer, a waterproof and dustproof layer is provided on one side of the base layer, a wear-resistant layer is provided on the other side of the base layer, the outer side of the wear-resistant layer is serrated, and a circular hole is provided at the lowest point of the serrated edge of the wear-resistant layer, and the circular hole passes through the wear-resistant layer and penetrates into the base layer. The technical solution provided by the utility model has the beneficial effect that cement penetrates into the circular hole through the setting of the circular hole penetrating the wear-resistant layer, and the cement penetrates the wear-resistant layer and penetrates into the base layer, so that it is easy to combine with the base layer as a whole, and the strength of the combination is upgraded, and the wear resistance is upgraded.

[0004] Although the above patents solve the problems in the above-mentioned background technology, they still have the following shortcomings: 1. The wear resistance of the coated felt is improved by a wear-resistant layer. This wear-resistant method is too simple, which makes the wear resistance of the coated felt poor, and is not conducive to long-term use, reducing the practical effect of the coated felt; 2. There is no effective water barrier between the coated felt and the cement. Therefore, during laying, the coated felt is easy to absorb moisture in the cement, resulting in a weakening of the strength of the cement, thereby reducing the firmness between the coated felt and the cement, and cannot meet the needs of the installers.

[0005] In summary, the utility model solves the problems in the above-mentioned background technology by designing a glass fiber cement coating felt which is easy to be firmly combined with cement. Utility Model Content
