Novel composite polyester felt and manufacturing method of novel composite polyester felt

Abstract

The invention discloses a novel composite polyester felt, the main components of the novel composite polyester felt comprise alkali-free glass fibers, polyester fibers and mixed fibers of other auxiliary fibers; the alkali-free glass fibers are 11-14 mum in diameter and 15-20 mm in length; the diameter of the polyester fibers is 4-8 mum; the auxiliary fibers accounts for 5 % of the mixed fibers; during the production of the polyester felt, the final forming of the polyester felt is realized by using an adhesive; the adhesive comprises the following parameters: 30-40 % of acrylic acid series, 20-35 % of unsaturated resin, 20-40 % of vinyl acetate series and 0.3-0.6 % of coupling agent. The novel composite polyester felt has performances such as stiffness and has good fracture-resistant and tear-resistant strengths. The novel composite polyester felt is mainly applied to projects such as thin asphalt concrete overlays of asphalt pavements and repairing and repair construction of steel bridges paved with asphalt surface layers and road stones. The quality of pavements can be improved, the service life of roads can be prolonged, the tracks and the uneven pavement, resulting from pavement canalization and strong pressure can be prevented.

Description

technical field [0001] The invention relates to a method for manufacturing building materials, in particular to a method for manufacturing a novel composite polyester felt. Background technique [0002] Polyester fiber is a high-performance synthetic fiber with acid resistance and good light resistance. It has strong adsorption with asphalt, which is also a petroleum product, and has good adsorption and dispersion in the medium. It can be widely used in hot-mixed asphalt concrete projects, and can also be used in the reinforcement and anti-cracking of high-strength concrete. It is an ideal multi-functional reinforcement material. Felt made of polyester fiber is commonly known as polyester felt. At present, the main component of the mat produced by the wet process is glass fiber. The mat produced with glass fiber has good stiffness and is widely used in the market. However, when applied to pavement engineering, due to its rigidity, it is easy to cause cracks and other pheno...
