Method for manufacturing one-step formed water-based adhesive kraft paper adhesive tape

Abstract

The invention discloses a manufacturing method of a one-step formed water-based adhesive kraft paper adhesive tape. The manufacturing method of the one-step formed water-based adhesive kraft paper adhesive tape comprises the following steps: step 1, diluting and preparing a water-based thermocuring adhesive according to a ratio for later use; step 2, supplementing water to untreated raw kraft paper by using diluted thermosetting adhesive, rolling, and standing for 60 minutes for later use after rolling; 3, continuously compacting the raw paper supplemented with water at high temperature and overpressure through an overpressure machine; 4, coating one surface of the paper with a layer of water-based silicone oil through a reticulate pattern gluing roller; and 5, after drying, rolling is carried out. Step 6, coating a non-release surface with a water-based pressure-sensitive adhesive by using a scraper gluing machine; step 7, drying for the second time and rolling; and step 8, slitting and packaging to obtain the product. The plastic-free degradable adhesive tape has the advantages that the plastic-free degradable adhesive tape is plastic-free and can be completely degraded, the adhesive tape is high in firmness after overpressure is adopted, and the water-based pressure-sensitive adhesive is adopted, so that the air temperature, climate and retention period of regions in various dimensions can be overcome, and the plastic-free degradable adhesive tape can be used in all weathers.

Description

technical field [0001] The invention relates to the field of tape processing, in particular to a method for making a one-time water-based adhesive kraft paper tape. Background technique [0002] The adhesive tape is composed of two parts: the base material and the adhesive. It connects two or more disconnected objects together by bonding, and the surface is coated with a layer of adhesive. Conventional adhesive tapes in the prior art are usually made of materials such as resins, and in the production process, more solvents are often used, and more materials that are difficult to degrade naturally are used, thereby causing serious environmental pollution. In the prior art, there are also water-based adhesive tapes that use water-based pressure-sensitive adhesives as adhesives. The characteristics are between ordinary double-sided adhesive tapes and oily double-sided adhesive tapes. In the prior art, acrylic monomers are usually emulsified under the action of surfactants. , a...

AI Technical Summary

Problems solved by technology

Conventional tapes in the prior art are usually made of resin and other materials, and more solvents are often used in the production process, and more materials that are difficult to degrade naturally are used, resulting in serious environmental pollution.

In the prior art, there are also water-based tapes that use water-based pressure-sensitive adhesives as adhesives. The characteristics are between ordinary double-sided tapes and oily double-sided tapes. In the prior art, acrylic monomers are usually emulsified under the action of surfactants. , and obtained by emulsion polymerization with water as the medium, it cannot be processed with water glue, resulting in poor environmental protection of the product

In addition, the pressure-sensitive adhesives in the prior art usually need to be applied in the form of coating or caulking, which involves relatively many steps and low processing efficiency
