[China Glass Net] We know that the main component A of the insulating glass two-component adhesive is not cured. It will only gradually solidify after a certain amount of vulcanizing agent. In order to accelerate the curing speed of the rubber, our door is glued. A certain amount of vulcanization accelerator is added to the curing agent to accelerate the reaction speed of the vulcanizing agent and the main glue. When we artificially increase the proportion of the curing agent in order to accelerate the curing of the rubber, the rubber increases the vulcanization speed but the rubber The quality of the product itself has been reduced. We found that the glue that was cured by accelerated vulcanization was broken. The glue at this time was much softer than the normal rubber, like a foamed sponge. Therefore, our workers used the two-component glue. In order to ensure the quality of the glue as much as possible, it must be in accordance with the standard proportion and fully mixed to prevent the high local accelerator content of the glue and affect the overall quality of the insulating glass.

The raw materials used in the insulating glass two-component adhesive have strong adhesion, but the material of the strong adhesive force needs to meet the performance requirements. The two-component adhesive used by us. Its preferred adhesion (with glass and aluminum strips) is applied to the desired coating area immediately after it is added with a specified amount of curing agent to complete the vulcanization from the beginning of the coated part - completely In the process of vulcanization, if we apply the glue to the desired part under the semi-vulcanized state, the bond strength will have a great influence.

I have done such an experiment, prepared 200 pieces of glass samples to be cleaned and dried, and the qualified two-component glue was mixed at a standard ratio once, and the glue was applied to the sample glass sheets every 10 seconds under the same environmental conditions. When applied to 116 samples, the glue has lost the bonding ability. After one day, the adhesion of the rubber to the glass was tested. It was found that the adhesion decreased with the strengthening of the vulcanization until the adhesion was completely lost. . Recalling that a hollow glass produced by a friend had been mistaken in size, there were more than 100 pieces of insulating glass and it was scrapped in the open air. After half a year, it was found that some of it had been cracked and degummed, and some were intact, and friends could not understand it. , the same materials, the same workers, the same production process, the same storage environment, why there is a different sealing effect? The real reason is that there is too much glue, and the cracked hollow glass is applied to the glass under different degrees of vulcanization, and the glue is applied in a semi-cured state.
