Embodiment Construction

[0027] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the present invention will be further described in detail below in conjunction with specific embodiments.

[0028] The invention provides a polyester tire. The polyester tire is obtained by impregnating a non-woven fabric with an impregnating liquid, and the impregnating liquid includes a fluorine-based waterproofing agent and cornstarch glue.

[0029] The surface tension of the polyester tire is 38-43 dynes.

[0030] The polyester tire provided by the invention has a surface tension of 38-43 dynes, preferably 39-41 dynes. On the one hand, in the subsequent process of coating modified asphalt to prepare waterproof membrane, the surface tension of the polyester tire prepared by the present invention is higher than that of asphalt (29-31 dynes), which facilitates the asphalt in the polyester tire. On the other hand, in the actual construction and application...

Abstract

The invention provides a polyester reinforcement and a preparation method of the polyester reinforcement. The polyester reinforcement belongs to the technical field of waterproof membranes, and can solve the problem that the waterproof effect of an existing waterproof membrane can be reduced due to improper construction in a construction process. The polyester reinforcement provided by the invention is obtained by impregnation of a non-woven fabric in impregnation liquid, and the impregnation liquid contains a fluorine-containing waterproof agent and a corn starch adhesive. After water enters the end surface of the waterproof membrane in the construction process, the polyester reinforcement provided by the invention can effectively prevent the water from wetting and penetrating the interior of the waterproof membrane, so that the service life of the waterproof membrane is effectively prolonged, the waterproof effect of the waterproof membrane is effectively improved, the risk of water seepage is reduced, and the hidden danger of water seepage is eliminated.

Description

technical field [0001] The invention belongs to the technical field of waterproof coiled material, and in particular relates to a polyester tire, a preparation method thereof, and a waterproof coiled material. Background technique [0002] Waterproof membrane polyester tire is also called polyester felt. In the production process, polyester staple fibers or polyester chips are made into non-woven fabrics of specified weight, and then heat-set, dipped, and dried. into. Among them, the non-woven fabric is a non-woven fabric produced from polyester staple fiber or a non-woven fabric web produced by a polyester chip spunbond method, and is produced by thermal bonding or chemical bonding by a needle punching method. The main function of the heat setting and dipping steps is to ensure that the polyester tire will not be narrowed or deformed during the process of impregnating bitumen in the subsequent processing of styrene-butadiene-styrene block copolymer (SBS) waterproofing memb...
