Polyester basalt fiber cloth and preparation method thereof

Abstract

The invention relates to a piece of polyester basalt fiber cloth and a preparation method thereof, and provides an excellent novel geotechnics material which can be used for pavement construction and maintenance works to play the roles of water prevention and ribbing, and can effectively prevent and process pavement distresses like pavement cracks and pavement water damages, and can be simultaneously used for slope protection and soft foundation reinforcing treatment. The polyester basalt fiber cloth is formed by spraying glue on non-woven fabrics woven by blending basalt fibers and polyester fibers. The polyester basalt fiber cloth is characterized in that the respective advantages of the basalt fibers and the polyester fibers are combined; namely, the high elasticity modulus and the high tensile strength of the basalt fibers as well as the toughness and the oleophylic performances of the polyester fibers are sufficiently utilized. The polyester basalt fiber cloth has all the characteristics of common nonwoven geotextile, has excellent waterproof performance, construction performance and ribbing performance, and simultaneously has excellent mechanical performance and asphalt absorption performance.

Description

technical field [0001] The present invention relates to polyester basalt fiber cloth and its preparation method, especially provides a high-quality new geotechnical material that can be used for waterproofing and reinforcement in road construction and maintenance projects, and can effectively prevent and treat road surface cracks and road water damage, etc. Pavement disease, but also can be used for slope protection and soft foundation reinforcement treatment. Background technique [0002] By the end of 2009, the mileage of expressways in my country had reached 65,000 kilometers. In the expressway, asphalt pavement is favored by many countries in the world for its good mechanical properties, flat and wear-resistant surface, smooth and comfortable driving performance, less dust, less vibration, low noise, short construction period and easy maintenance and repair. , are widely used in highways. However, due to the harsh working conditions of the asphalt pavement, in addition...

Problems solved by technology

The glass fiber grid has a certain effect on alleviating cracks, but because the glass fiber grid is a grid material, the contact between it and the asphalt layer is a point-line contact, so the reinforcing effect is not sufficient; in addition, the glass fiber grid The grid does not have waterproof function, and the moisture on the upper layer penetrates into the old cracks, which will accelerate the destruction of the road surface; polyester fiberglass cloth is a mixture of glass fiber and polyester fiber, which has the strength of glass fiber and the flexibility of polyester fiber, but Indoor tests show that the ability of polyester fiberglass cloth to penetrate asphalt is small, which will reduce the interlayer bonding performance to a certain extent. Its waterproof and reinforcing effect and bonding effect
