Hot sticking glue for fire hose lining glue and preparation method thereof

Abstract

The invention discloses a hot sticking glue for a fire hose lining glue and a preparation method thereof. The hot sticking glue comprises the following components by weight percent: 10%-14% of poly ammonia ketone hot melt adhesive particles and 86%-90% of acetone. The preparation method of the hot sticking glue is implemented according to the following steps: firstly, quantificationally injecting acetone into a mixing container; uniformly adding measured polyurethane hot melt adhesive particles into acetone, and mixing and stirring for 10-15 minutes; then heating the outer wall of the mixing container to 55-60 DEG C, in the heating period, controlling the temperature of a mixture of acetone and the polyurethane hot melt adhesive particles at 37-40 DEG C, and stirring for 160-200 minutes, thereby preparing the hot sticking glue. The hot sticking glue disclosed by the invention has the advantages of simple components, no pollution discharge in the production process and no benzene vestigital in products, and meets environment protection requirements; above all, after being subjected to hot sticking, a coating has high antistripping intensity and meets production requirements of the fire hose lining glue.

Description

technical field [0001] The present invention relates to a kind of synthetic adhesive, in particular, the present invention relates to a kind of glue which can be bonded under the hot-melt state, and the glue is used for bonding the fire hose and the matched lining. The invention also relates to a method for the preparation of thermal adhesives. Background technique [0002] The fire hose is a hose that carries water under pressure. It consists of an outer fiber hose and an inner tubular PVC lining. In order to improve the fitting quality of the inner and outer layers of the fire hose during the production process, hot glue is usually applied on the joint surface of the two, and then bonded under the conditions of temperature and pressure set by the process. The solvent used in commercial thermal adhesives on the market is xylene. This solvent has strong dissolving power, fast volatilization, and is convenient for painting. The bonding quality of the prepared thermal adhesiv...

Problems solved by technology

However, xylene is a colorless and transparent liquid with moderate toxicity. The gas containing high concentration of xylene discharged during the production process is harmful to the body of production line workers, especially irritating to the eyes and respiratory tract of operators. even harm the central nervous system

In addition, the fire hoses produced with the prior art hot viscose still have xylene residues within a certain period of time, and users are also polluted when using them.
