Problems solved by technology

At present, most of the glues available in the market are organic solvent-based liquid glues. Since organic solvents are toxic to varying degrees, they will pose a hazard to the health and environment of athletes, table tennis enthusiasts or pasters when used.
However, water-based glue dries slowly, which brings inconvenience to on-site pasting

Embodiment 1

[0023] Apply a layer of N-1 solvent natural rubber pressure-sensitive adhesive on the rubber sponge of the traditional table tennis racket, control the thickness of the dry film to about 10 μm, and pass through a drying tunnel at about 80°C for about 60 seconds to remove the organic solvent, and then apply it on the pressure-sensitive adhesive. A piece of 60g glassine release paper is pasted on the surface of the table tennis racket to obtain the pre-coated table tennis racket cover glue of the present invention.

Embodiment 2

[0025] Apply a layer of S-792 solvent styrene-butadiene rubber pressure-sensitive glue on the sponge of the traditional table tennis racket rubber, control the thickness of the dry film to about 18 μm, and pass through the drying tunnel at about 80°C for about 60 seconds to remove the organic solvent, and then apply the pressure-sensitive adhesive Paste one piece of 52g kaolin coated release paper on the surface of the glue, then obtain the pre-coated table tennis racket cover glue of the present invention.

Embodiment 3

[0027] Apply a layer of S-6201 solvent-butadiene rubber pressure-sensitive glue on the rubber sponge of the traditional table tennis racket, control the thickness of the dry film to about 25 μm, and pass through a drying tunnel at about 80°C for about 80 seconds to remove the organic solvent, and then apply the pressure-sensitive adhesive Paste one piece of 80g glassine release paper on the surface of the glue, then obtain the pre-coated table tennis racket cover glue of the present invention.

Abstract

The invention discloses a pregummed table-tennis rubber sheets and a manufacturing method, which comprises the sequential connected rubber protecting film, the rubber, the adhesive layer and the spongy layer, and also comprises the pressure sensitive sub connected with the profile material layer, the pressure sensitive sub connected with the spongy layer and the profile material layer sticking on the pressure sensitive sub. During the preparation, coating the sponge of the traditional table-tennis rubber sheets making from the rubber, the spongy layer and the adhesive layer with the pressure sensitive glue, and utilizing the profile materials sticking on the pressure sensitive sub to protect the pressure sensitive sub; the pressure sensitive sub is the pressure sensitive glue of rubber styles, the pressure sensitive glue of the acrylic ester or the thermal pressure sensitive glue. The invention has the advantages of repeated sticking and stripping after once gelatinizing, the good elasticity, the convenient use and taking and nontoxic, and overcomes the sticking shortage of the traditional table-tennis rubber sheets, which use toxic organic solvent glue or use the water glue with slow dryness.

Description

technical field [0001] The invention relates to table tennis racket cover rubber, in particular to a pre-coated table tennis racket cover rubber and a manufacturing method thereof. Background technique [0002] The rubber product is a kind of material for making table tennis rackets. The traditional table tennis racket rubber is made of two parts, rubber and sponge, pasted by glue. Athletes or table tennis enthusiasts can choose different table tennis bare boards and table tennis rackets according to their own preferences, and then paste and trim them with glue. Most of the glues currently available in the market are organic solvent-based liquid glues. Since organic solvents are toxic to varying degrees, they will pose a hazard to the health and environment of athletes, table tennis fans or pasters when used. However, the water-based glue dries slowly, which brings inconvenience to the on-site pasting. Contents of the invention [0003] The purpose of the present inventi...
