example 1

[0011] Example 1: First, use polyester yarn as warp and weft on a circular loom to weave a tubular fiber braided layer 1, then mix isocyanate and oligomer diol in a weight ratio of 1:0.6, as component A, amino-terminated poly Ether, liquid amine chain extender, filler and additives are used to form a slurry in parts by weight of 60:20:10:10 as the R component, and then the A component and the R component are fully mixed at a volume ratio of 1:0.8, At 60°C and a pressure of 12 MPa, use a spray gun to spray on the inner side of the fiber braided layer to form a polyurea elastomer coating 2; spray with a thickness of 0.5 mm and dry for 1 minute to obtain a single-sided adhesive tape.

example 2

[0012] Example 2: First, use high-strength aramid yarn as warp and weft on a circular loom to weave tubular fiber braided layer 1, then mix isocyanate and oligomer trihydric alcohol in a weight ratio of 1:0.7, as component A, Amino-terminated polyether, liquid amine chain extender, filler and additives are composed of slurry in parts by weight of 50:30:8:5, as the R component, and then the A component and the R component are fully mixed in a volume ratio of 1:1.2 After mixing, use a spray gun to spray on the inner side of the fiber braided layer at 65°C and a pressure of 14MPa to form a polyurea elastomer coating 2; spray with a thickness of 0.7mm and dry for 2 minutes to obtain a single-sided adhesive tape.

example 3

[0013] Example 3: First, use high-strength aramid yarn as warp and weft on a circular loom to weave a tubular fiber braided layer 1, then mix isocyanate and oligomer glycol in a weight ratio of 1:0.9, as component A, Amino-terminated polyether, liquid amine chain extender, filler and additives are composed of slurry in parts by weight of 55:35:10:5, as the R component, and then the A component and the R component are fully mixed in a volume ratio of 1:1. After mixing, use a spray gun to spray on the inner side of the fiber braided layer at 70°C and a pressure of 15 MPa to form a polyurea elastomer coating 2; spray with a thickness of 1.0 mm and dry for 1.5 minutes to obtain a single-sided adhesive tape.

Abstract

The invention discloses a single-side glue water belt and a preparation method thereof; the water belt consists of a fiber knitting layer and a polyurea elastomer coating which is used as a lining layer which has the thickness of 0.5-1.0mm; high-strength aramids are preferably selected for the warp and woof of the knitting layer; the preparation method comprises the steps as follows: tabular knitting layer is knitted on a circular loom firstly; subsequently, isocyanate composition and resin composition are mixed and heated to 60-70DEG C and pressurized to 12-15MPa; subsequently, the mixture is sprayed at the internal side of the fiber knitting layer by a spraying gun, thus forming a polyurea elastomer coating which is then dried so as to gain the product; the water belt is used for delivering water or industrial liquids in the industries such as fire control or agriculture and industry, building and the like, has the advantages of wearability, anti-corrosion, anti-impact, long service life and the like, has simple preparation method, few equipment investment, high production efficiency and meeting the requirement of environmental protection.

Description

technical field [0001] The invention relates to a single-sided glue tape used for fire protection or water delivery in industrial and agricultural production and a production method. Background technique [0002] The hose is a tool widely used in industry, agriculture, construction, fire protection and other industries to transport water or transport industrial liquids. Generally, the hose is lined with a layer of rubber layer in the fiber braided layer. The lining layer of this kind of hose is easy to age and fall off, the hose is not wear-resistant, and its service life is short. The manufacturing method of this kind of hose is: weave the fiber weaving layer on the circular loom first, then mix the rubber and compounding agent with the rubber mixing machine, filter through the rubber filter, use the extruder to make a hose, and pull it into the weaving layer After that, vulcanize with vulcanization equipment. This production method requires more production equipment, con...
