Abstract

The utility model discloses a base material of waterproof grid cloth, which consists of a weaving layer and binder layers at two sides of the weaving layer; the weaving layer is formed by weaving weft yarns and warp yarns, the weft yarns and the warp yarns are woven in a grid shape, the weft yarns are mixed yarn bundles composed of glass fiber spun yarns and polyester fibers, and the warp yarns are mixed yarn bundles composed of glass fiber bulked yarns and the polyester fibers. The utility model discloses a waterproof grid cloth's substrate, weaving layer are woven into latticedly by warp and woof, and the warp is the mixed yarn that glass fiber spun yarn and polyester fiber constitute, and the woof is the mixed yarn that glass fiber bulked yarn and polyester fiber constitute. Due to the addition of the polyester fibers, the woven base material has better toughness and is softer, and the knitted base material can adapt to various different planes. The binder layers on the two sides of the braided layer play a role in shaping and fixing the fibers, so that the subsequent resin impregnation operation is facilitated.

Description

Base material of waterproof grid cloth

Technical Field

The utility model relates to a glass fiber material, concretely relates to waterproof grid cloth's substrate.

Background

The mesh cloth can be used as a waterproof material. The waterproof mesh fabric is prepared by taking glass fiber woven fabric as a base material, then impregnating resin, and dripping glue and drying. The existing glass fiber woven fabric is usually woven by glass fiber spun yarns.

Chinese patent document CN 206814939U (application No. 201720340956.5) discloses a bulked yarn grid cloth, which comprises a grid cloth body, wherein the grid cloth body is woven by warps and wefts into a grid shape, the warps are composed of bulked glass fiber yarns, the wefts are composed of non-bulked glass fiber yarns, and the diameters of the warps are larger than those of the wefts.

The glass fiber spun yarn is relatively poor in bonding effect with the organic resin, and in addition, the flexibility of the mesh cloth needs to be improved.

SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the technical problem that a substrate of waterproof net cloth that the pliability is good, combine effectually with the resin is provided.

The technical scheme for realizing the purpose of the utility model is that the base material of the waterproof grid cloth consists of a weaving layer and binder layers at the two sides of the weaving layer; the weaving layer is formed by weaving weft yarns and warp yarns, the weft yarns and the warp yarns are woven in a grid shape, the weft yarns are mixed yarn bundles composed of glass fiber spun yarns and polyester fibers, and the warp yarns are mixed yarn bundles composed of glass fiber bulked yarns and the polyester fibers.

The volume ratio of the glass fiber spun yarn to the polyester fiber in the weft yarn mixed yarn bundle is 1: 2-4.

The volume ratio of the glass fiber bulked yarns to the polyester fibers in the warp mixed yarn bundles is 1: 2-4.

The thickness of weaving layer is 0.5 ~ 3 mm.

The thickness of the adhesive layer is 0.1 +/-0.02 mm.

The utility model discloses has positive effect: the utility model discloses a waterproof grid cloth's substrate, weaving layer are woven into latticedly by warp and woof, and the warp is the mixed yarn that glass fiber spun yarn and polyester fiber constitute, and the woof is the mixed yarn that glass fiber bulked yarn and polyester fiber constitute. Due to the addition of the polyester fibers, the woven base material has better toughness and is softer, and the knitted base material can adapt to various different planes. The binder layers on the two sides of the braided layer play a role in shaping and fixing the fibers, so that the subsequent resin impregnation operation is facilitated.

Detailed Description

(example 1)

Referring to fig. 1, the base material of the waterproof mesh fabric of the present embodiment is composed of a woven layer 1 and adhesive layers 2 on both sides thereof. The adhesive layer 2 completely covers the surface of the braid 1.

The woven layer 1 is woven by weft yarns and warp yarns, and the weft yarns and the warp yarns are woven in a grid shape.

The weft yarn is a mixed yarn bundle composed of glass fiber spun yarns and polyester fibers, and the volume ratio of the glass fiber spun yarns to the polyester fibers in the mixed yarn bundle is 1: 2-4.

The warp yarns are mixed yarn bundles consisting of glass fiber bulked yarns and polyester fibers, and the volume ratio of the glass fiber bulked yarns to the polyester fibers in the mixed yarn bundles is 1: 2-4.

The thickness of the braided layer 1 is 0.5-3 mm, and 2mm in this embodiment.

The adhesive layer 2 is a coating obtained by coating an adhesive on the woven layer 1 and drying the adhesive, and is used for shaping and fixing the fibers. The binder is an acrylic binder such as white latex. The adhesive layer 2 in this embodiment is a white latex layer, and has a thickness of 0.1 ± 0.02 mm.

The base material of the waterproof grid cloth of the utility model is impregnated with hydrophobic resin and is dripped with glue to be dried to obtain the waterproof grid cloth.

The polyester fiber is added into the base material weaving layer, so that the base material obtained by weaving and shaping has better toughness and is softer, and the base material can adapt to various different planes. The binder layers on the two sides of the braided layer play a role in shaping and fixing the fibers, so that the subsequent resin impregnation operation is facilitated.
