AI Technical Summary

Problems solved by technology

Since the fiberglass mesh does not have any extension, it cannot resist the destructive force on the decorative surface after the wall continues to crack, causing damage to the decorative surface and affecting the appearance.
Brushing styrene-acrylic emulsion bonded mesh cloth needs to be fully cured before the emulsion can be effective. It takes more than 7 days for the emulsion to cure to meet the strength requirements. If the construction time is too long, the subsequent construction progress will be affected.

Abstract

The invention provides a modified self-adhesive EVA chip and a wall repairing tape, and production methods thereof. The modified self-adhesive EVA chip is produced from, by weight, 90-110 parts of EVAresin, 5-16 parts of synthesized rubber SIS, 12-22 parts of a tackifier, 3-14 parts of petroleum resin, 6-15 parts of terpene resin and 1-7 parts of a coupling agent. The EVA resin is modified to have the self-adhesive properties while having original properties in order to obtain the modified self-adhesive EVA chip; and the wall repairing tape changes the production process of existing self-adhesive material coating, and prevents deformation and performance deterioration of polymeric sheets, caused by traditional roller coating of polymeric materials with a self-adhesive material, and the pollution of high-temperature volatiles of the self-adhesive liquid material to the environment during secondary molding.

Description

technical field [0001] The invention belongs to the technical field of decoration and building materials, and in particular relates to a modified self-adhesive EVA chip, a wall repair tape and a preparation method. Background technique [0002] At present, most of the materials used to repair wall cracks in home decoration projects are glass fiber mesh cloth plus white latex (styrene-acrylic emulsion). Since the glass fiber mesh cloth does not have any extension, it cannot resist the destructive force on the decorative surface after the wall continues to crack, causing damage to the decorative surface and affecting the appearance. Brushing styrene-acrylic emulsion bonded mesh cloth needs to be fully cured before the emulsion can be effective. It takes more than 7 days for the emulsion to cure to meet the strength requirements. If the construction time is too long, the subsequent construction progress will be affected. Problems such as discoloration of the wall, low strength...
