Waterproof voile production technology, and special production equipment thereof

Abstract

The invention belongs to the technical field of waterproof materials, and especially relates to a waterproof voile production technology. The waterproof voile production technology comprises followingsteps: raw material preparation, waterproof solution preparation, and glue solution preparation, wherein the raw material is glass fiber, the waterproof solution comprises 35 parts of water, 5 partsof acrylic acid, 2 to 2.5 parts of 30% sodium hydroxide aqueous solution, 0.1 to 0.15 part of a cross-linking agent, 0.1 to 0.2 part of an initiator, and an auxiliary agent, and the glue solution comprises 150 parts of water, and 10 parts of a polyacrylate emulsion with a solid content of 50%; primary dip padding; drying; secondary dip padding; secondary drying; drafting; and coiling. After drying, a double layer waterproof structure is formed by the waterproof solution and the glue solution, the waterproof voile water absorbing swelling speed and the sealing waterproof performance are improved; a plurality of times of drying treatment and temperature control is capable of realizing reaction of components in the waterproof solution and the glue solution, the physical/chemical performance of the waterproof voile is improved. The whole process is easy to control, no special equipment is needed, and the production cost is relatively low.

Description

technical field [0001] The invention relates to the technical field of water-blocking materials, in particular to a production process of water-blocking glass yarn and special production equipment thereof. Background technique [0002] Water-blocking glass fiber yarn is a new type of non-metallic cable strength member, which is widely used in optical cables, especially dry optical cables. During the laying and routing of communication optical cables, they are sometimes affected by water and moisture. If water and moisture invade the interior of the optical cable, it will seriously affect the quality of the optical cable transmission signal. In order to solve the above problems, ensure the safe operation of the optical cable and prolong the service life, the following methods are usually used to prevent moisture: 1. Fill the interior of the optical cable with thixotropic ointment. This type of material is oily, with a large filling amount and low cost. High, difficult to cle...

Problems solved by technology

In the process of laying and routing communication optical cables, they are sometimes affected by water and moisture. If water and moisture invade the interior of the optical cable, it will seriously affect the quality of the optical cable transmission signal

In order to solve the above problems, ensure the safe operation of the optical cable and prolong the service life, the following methods are usually used to prevent moisture: 1. Fill the interior of the optical cable with thixotropic ointment. This type of material is oily, with a large filling amount and low cost. High, difficult to clean, easy to pollute the environment, and lead to excessive weight of the optical cable; 2. Use hot-melt adhesive water blocking rings between the inner and outer sheaths. This method is complicated and cumbersome, and currently only a few manufacturers can achieve it; 3. , Using dry expansion powder water-blocking material, this method requires high process requirements, large amount of materials, high cost, and the weight of the optical cable is also large
