Embodiment Construction

[0013] Specific embodiments of the present invention:

[0014] (1) Control raw materials: the moisture content of chopped fibers: 8%-12%; the moisture content of chopped fibers should be controlled at 8%-12%, the moisture content is lower than the process requirements, and the chopped fibers are unevenly dispersed. The occurrence of bunching will lead to a decrease in the strength of the thin felt. Reasons for the decrease of the moisture content of the chopped fiber, A: The moisture content of the raw silk drum decreases due to the delay in the transportation and chopping process. B: Chopped fibers are transported from the chopped process to the feeding process or stored for too long, resulting in a decrease in moisture content. We restrict suppliers by specifying the moisture content of chopped fibers in the contract to ensure that the moisture content of our chopped fibers meets the process requirements. At the same time, we pass strict raw material inspection procedures, ...

Abstract

Provided is a low-gel-content glass fiber reinforced mat for a waterproof coiled material. The low-gel-content glass fiber reinforced mat for the waterproof coiled material is prepared from glass fiber short shreds, glass fiber reinforced yarns and adhesive through a wet method. The main technical parameters are as follows: gram weight is 45g / m2+ / 3g, longitudinal tensile strength is larger than or equal to 150N / 5cm, transverse tensile strength is larger than or equal to 50N / 5cm, and gel content is smaller than or equal to 17%. The low-gel-content glass fiber reinforced mat for the waterproof coiled material has the advantages of being corrosion resistant, good in anti-aging performance, high in void content, easy to steep in asphalt, long in service life and stable in size. Due to a relatively low gel content, steep of the mat in the asphalt is benefited in the process of producing the waterproof coiled material, steeping time in the asphalt is reduced, and therefore production speed of the waterproof coiled material is increased.

Description

Technical field: [0001] The invention relates to a thin glass fiber felt, in particular to a glass fiber thin felt with low glue content and reinforced ribs. Background technique: [0002] With the continuous expansion of the application field of glass fiber mats, higher requirements are put forward for the three technical indicators of longitudinal tensile strength, transverse tensile strength and bursting resistance of glass fiber mats. The existing glass fiber thin mats all adopt the wet felting method: it includes the steps of slurry preparation, sizing and molding, dipping and sizing, and drying and coiling. [0003] At present, the waterproof membrane used for road construction needs to use low-glue glass fiber reinforced thin felt. Its technical parameters are: weight 45g / ㎡±3g, longitudinal tensile strength: ≥150N / 5cm, transverse tensile strength: ≥50N / 5cm; glue content less than 17%, good corrosion resistance, aging resistance, high porosity, which is easier to be i...
