Embodiment Construction

[0016] The structure and application principle of the reinforced glass fiber chopped strand mat of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0017] As shown in the figure, the reinforced glass fiber chopped strand mat of the present invention includes a mat body composed of a chopped glass fiber layer 1, and a polyester thread reinforcing rib 2 is arranged in the chopped glass fiber layer 1.

[0018] When manufacturing, the glass fiber precursors are selected first, and then the glass fiber precursors are sent to the chopping machine, and the glass fiber precursors are chopped into 40-60mm long chopped glass with a length of 50mm. Fibrous filaments. Then, evenly settle the chopped glass fiber, and add 5-8% of its weight of binder and 0.3-0.4% of its weight of sizing agent into the chopped glass fiber, and melt it at 100-130°C The chopped glass fiber strands and the adhesive are bonded into a mat at high te...

Abstract

The invention belongs to the technical field of fiber glass composite material and discloses enhancement mode fiber glass chopped strand mat and a preparation method thereof. The main technical characteristics lie in that the invention comprises a felt body which is formed by chopped fiberglass laminate; the interior of the chopped fiberglass laminate is provided with polyester thread strengthening rib. The enhancement mode fiber glass chopped strand mat provided by the invention is lengthways provided with the polyester thread strengthening rib in the felt body which is formed by the chopped fiberglass laminate. Compared with the current Chopped strand mat, the enhancement mode fiber glass chopped strand mat is added with the longitudinal polyester thread strengthening rib to strengthen the longitudinal tensile force which is two to three times of the common chopped strand mat, has good mechanical property and high mechanical strength, when being applied to FRP products, roofing water proofing building materials, and the like, the service life is prolonged to be 10 to 15 years of products, meanwhile, the product is characterized by uniform distribution, rapid velocity of permeability, good coated performance and low cost.

Description

technical field [0001] The invention belongs to the technical field of glass fiber composite materials, in particular to a reinforced glass fiber chopped strand mat and a preparation method thereof. Background technique [0002] my country uses 100 million cubic meters of corrosion-resistant steel pipes every year, and exports 10,000,000 tons of FRP products every year, and with the rapid economic development, it increases at a rate of 30% every year. In addition, FRP chemical anti-corrosion pipelines, refrigerated car boxes, car roofs, high-voltage insulating materials, reinforced plastics, and various FRP products such as boats, sanitary ware, seats, flowerpots, building components, entertainment appliances, and statues are also widely used . When manufacturing FRP products, it is necessary to lay glass fiber non-woven mats. Glass fiber non-woven mat is divided into chopped strand mat and continuous mat. Chopped strand mat is made by chopping continuous glass fiber to a...
