Adhesive bonding process of polyethylene agricultural film

Abstract

The present invention discloses an adhesive bonding process of a polyethylene agricultural film. The adhesive bonding process is characterized in by including the following requirements: (1) an adhesive: an EVA hot melt adhesive or a pressure-sensitive rubber-type adhesive; and (2) the adhesive bonding process: a, surface treatment: firstly, washing a film need to be patched with water to be clean, air-drying the clean film, wiping up broken leaks and a patching film with trichloroethylene to activate the films; and b, bonding and solidifying, brushing a layer of the EVA hot melt adhesive or the pressure-sensitive rubber-type adhesive on a bonded surface with a hair brush, respectively, conducting airing for 10-20 minutes, pasting the patching film at the inner layer of the broken leaks when the adhesive is stick but not stick to hand by touching with the fingers, squeezing out bubbles with the hand at the same time, tightly compressing the two layers of films, and solidifying the adhesive at room temperature for 12-20 hours, thereby finishing the adhesive bonding process. The adhesive bonding process is reasonable in procedures, low in cost, reasonable and harmonious in match of various parameters, short in time and simple in operation.

Description

technical field [0001] The invention relates to a bonding process of polyethylene agricultural film. Background technique [0002] Polyethylene agricultural film is easy to be damaged by strong winds, heavy rain, heavy snow and hail. Since polyethylene is a difficult-to-stick material, it needs to be surface activated before being repaired with adhesives. The existing maintenance plan is different from other The process arrangement is unreasonable, the process is numerous, and the time is long, which can no longer meet the requirements and needs to be improved to improve performance. Contents of the invention [0003] In view of the above-mentioned defects of the prior art, the technical problem to be solved by the present invention is to provide a polyethylene agricultural film bonding process with reasonable process, simple operation, short time and low manufacturing cost. [0004] In order to achieve the above object, the invention provides a kind of bonding process of...
