The rubber sheet bonding technique is a technique that utilizes an adhesive to join a rubber sheet to another material to form a continuous, strong, stable, unitary structure. In actual production, according to the specification that HG6-415-79 is the material standard of aviation rubber liquid and chloroprene rubber adhesive, when a chloroprene rubber adhesive is used for bonding a rubber plate and a metal plate, the rubber plate is firstly manufactured by accurately blanking according to the size of a metal plate adhesive area, the chloroprene rubber adhesive is uniformly coated on the rubber plate and the metal plate adhesive area, then the rubber plate stays for about 15min, then the rubber plate is attached to the metal plate adhesive area and is pressed tightly, and corresponding holes are manufactured on the rubber plate according to the position and the hole diameter of a lead hole on the metal plate. Because the chloroprene rubber adhesive is a solvent adhesive, the solvent can slowly volatilize under the condition of room temperature, and the chloroprene rubber in the adhesive is recrystallized and generates stress of inward shrinkage.

Comparative example 1
Bonding rubber sheets using a chloroprene rubber adhesive
The method comprises the following steps:
And 2, preparing a rubber plate 2, wherein the area of the rubber plate 2 is the same as that of the first adhesive area 11.
And 3, cleaning the surface of the second adhesive area 21, uniformly coating a first chloroprene rubber adhesive in the second adhesive area 21, and standing for 15 min.
And 4, cleaning the surface of the first adhesive area 11, uniformly brushing a second chloroprene rubber adhesive in the first adhesive area 11, and standing for 15 min. And then correspondingly adhering the rubber plate 2 obtained in the step 3 to the first adhesive area 11, wherein the first chloroprene rubber adhesive on the rubber plate 2 is contacted with and adhered to the second chloroprene rubber adhesive on the first adhesive area 11, and the rubber plate 2 is adhered by pressing.
Step 5, cutting the bonded rubber plate 2 obtained in the step 4 by contrasting the first adhesive area 11; holes are then made in the rubber sheet 2, in relation to the position and diameter of the holes 12 in the panel 1.
Because the chloroprene rubber adhesive is a solvent adhesive, the solvent can slowly volatilize under the condition of room temperature, and the chloroprene rubber in the adhesive is recrystallized and generates stress of inward shrinkage. Under the effect of shrinkage stress, the rubber plate bonded on the metal plate can shrink from the periphery to the center, so that the rubber plate deforms, the partial viscose area on the metal panel is exposed outside, and the holes on the rubber plate and the holes on the metal panel are staggered.
Comparative example 2
Comparative example 2 provides the same procedure for bonding rubber sheets using a chloroprene rubber adhesive as in example 1, except that the shortest width of the margin region 111 in step 2 is 15 mm. The remaining steps and process parameters were the same as in example 1.
Researches find that after the bonding is finished, the first adhesive area cannot be completely covered at the shortest width of the margin area, and the first adhesive area is exposed outside and cannot meet the size accuracy of the rubber plate.
Comparative example 3
Comparative example 3 provides the same procedure for bonding rubber sheets using a neoprene adhesive as in example 1, except that in step 3, the second adhesive area 21 is placed face up for 15 h. The remaining steps and process parameters were the same as in example 1.
Research shows that after the bonding is finished, probably because the standing time in the step 3 is too short, the holes on the rubber plate are still slightly dislocated after the holes are formed in the step 5 in the comparative example 3, and the product quality requirement is not met.
Comparative example 4
Comparative example 4 provides the same procedure for bonding rubber sheets using a chloroprene rubber adhesive as in example 1 except that in said step 3, the second adhesive area 21 is placed face up for 35 h. The remaining steps and process parameters were the same as in example 1.
It was found that in comparative example 4, when the bonding treatment of step 3 was performed, the adhesiveness of the first chloroprene rubber adhesive on the second adhesive region 21 was decreased, which affected the bonding quality and resulted in a decrease in the sealability of the bond.
The method provided by the invention comprises the steps of firstly determining a first adhesive area on a panel to be bonded, then dividing a second adhesive area on a rubber plate, wherein the second adhesive area can completely cover the first adhesive area and has a margin area, coating a chloroprene rubber adhesive on the second adhesive area, standing for more than 18h, coating the chloroprene rubber adhesive on the adhesive area on the panel, standing according to a conventional method, correspondingly bonding the rubber plate to the first adhesive area, and pressing to complete bonding of the rubber plate. The method has the advantages that the quality of the bonded rubber plate product is effectively controlled by adjusting the area of the adhesive area in a targeted manner and the standing time after the adhesive is coated, the problems of size reduction and hole making dislocation of the bonded rubber plate after bonding are fundamentally solved, a large amount of reworking and repairing work caused by incapability of assembling the bonded part in the subsequent assembling link is greatly reduced, the manufacturing cost and the time cost are saved, the method is suitable for bonding rubber plates with different appearance sizes, and the popularization is facilitated.
The above description is intended to be illustrative of the preferred embodiment of the present invention and should not be taken as limiting the invention, but rather, the intention is to cover all modifications, equivalents, and alternatives falling within the spirit and scope of the invention.
