Embodiment Construction

[0016] Embodiments of the invention. The production method is as follows: a. Soak the nylon cloth in glue, dry it in the shade, and stretch it for later use. The role of dipping is to improve the adhesion between nylon cloth and film. The glue used can be natural latex. After testing, the ratio of 30-70 parts of natural latex, 1-10 parts of sodium hydroxide, and 10-30 parts of soft water is used. ,Better results. Tensioning is to stretch the nylon cloth to improve the resistance to bursting and breaking of the product. The tension of the nylon cloth is 80-120N.

[0017] b. The rubber is mixed, vulcanized, and pressed into a film. Film can be made into film after vulcanizing with natural rubber according to the way of existing rubber film.

[0018] In order to reduce the cost, natural rubber (with a weight ratio above 65%) and reclaimed rubber can be added with a vulcanizing agent, mixed and vulcanized at 70-85°C, and then pressed to obtain a film. The vulcanizing agent can...

Abstract

The invention discloses a production method of nylon geotextile, comprising the following steps: a, dipping nylon cloth in gum, drying in shade, and tensioning for use; b, mixing, vulcanizing and pressing rubber into a film; and c, rolling the film and the nylon cloth to obtain the geotextile. Property of the nylon geotextile prepared by the invention is superior to the prior geotextile products. After tested by related departments, intensity, bursting resisting strength and anti-penetrability property of the product all can meet requirements of sealing construction of the prior foundation bed, and the quality indexes of the product can reach standard of international similar products, whereas the price of the product is much lower than that of the international similar products. When the geotextile is used, yellow sand cushion is not necessary be added after discharging fragment and screening, and the geotextile is directly paved at position 300mm below bellow a crosstie directly, thus sealing construction of foundation bed is simplified, the labor intensity is reduced and sealing effect can be guaranteed.

Description

technical field [0001] The invention relates to a method for producing nylon geotextiles, belonging to the technical field of geotextiles. Background technique [0002] In recent years, with the leap-forward development of railway transportation, the transportation capacity has been continuously increased, resulting in frequent occurrence of railway subgrade mud and mud, subgrade subsidence, and extrusion. In the practice of continuous disease control, the main control measures based on subgrade sealing and replacement have been summarized and widely promoted. However, geotextiles, geomembranes, and drainage boards, which are the main materials of the sealing process, are limited by the process, and the burst strength, toughness, and tensile breaking capacity of these materials cannot withstand the impact load of the train. As a last resort, a layer of 15cm medium-coarse sand can only be laid on the top and bottom of the sealing material as a buffer protection layer to ensu...
