Description

The invention relates to the production of adhesives for adhesive tapes based on plasticized polyvinyl chloride for protecting surfaces made of glass, plastics, aluminum, stainless steel, anodized metals and plastics from scratches and soils, for repairing books and drawings, as an adhesive carrier for cutting. semiconductor wafers into crystals.

The purpose of the invention is to reduce the force of unwinding the adhesive tape from a roll while maintaining high cohesive strength of the adhesive to the substrate.

Adhesive tape is made as follows.

1. Preparation of adhesive composition.

The solvent and the plasticizer, chloroparaffin are loaded into the reactor with a stirrer, stirred for 5–10 min, after which perchlorovinyl is introduced.

resin, rosin and stirring are continued until the glue components dissolve completely for 3-4 hours. The process is carried out by heating to 45-50 ° C to form a homogeneous mass.

Examples of glue compositions are given in table .. 1.

The solvent consists of a mixture of dichloroethane (DCE), cyclohexane (CTC) and methylene chloride (MX) ..

When the ratio of DCE, GSS and MX is 1: 1: 1, the glue does not provide a high-quality adhesive LAYER when watered on a substrate; the ratio of DCE, CGS and MX 2: 2: 1 and 3: 2: 1 does not completely dissolve the PSH resin; at a ratio of DCE, CHS and MX 4: 3: 1, a PSC resin (HP) is planted from the cast adhesive; when the ratio of DCE, CHS and EM is 4: 1: 1, the components of the glue are completely grown (L

they are stolen, but the applied glue warps and deforms the film.

2. Applying adhesive composition.

Adhesive tape is obtained by applying the glued composition on a plasticized PVC substrate 85 85 m in thickness, TU 6-19-081-160-86 on a roller sprinkler at a speed of movement of the film web equal to 2.5 - 3. m / min, followed by 1 | Hermobrand, adhesive tape tape at T5-80 C.
