The bonding of acrylic sheets is a very important part in the processing of acrylic products. How to show the clear and transparent characteristics of acrylic, reflect the value of acrylic crafts, maximize the grade and taste of acrylic crafts, bonding technology plays a decisive role here.
The bonding of acrylic sheets is mainly affected by two aspects, one is the applicability of the adhesive itself, and the other is the bonding technique. At present, there are many kinds of adhesives on the domestic and foreign markets, and there are mainly two types, one is a solvent type, and the other is a resin type. Generally, a resin type adhesive is bonded by a curing reaction, and a solvent type adhesive is bonded by the final volatilization of a solvent.
The resin type adhesive is characterized by good bonding effect, no bubbles after bonding, no whitening, and high strength. The disadvantages are complicated operation, high difficulty, long curing time, slow speed, and difficulty in adapting to mass production. The general solvent adhesive is characterized by high speed and can meet the requirements of mass production. The disadvantage is that the bonded product is easy to produce bubbles, easy to be white, and has poor weather resistance, thereby directly affecting the external appearance and the quality of the mouth of the acrylic product.
Therefore, in the processing of acrylic products, how to choose a suitable adhesive to improve the taste and grade of acrylic products is a big problem that must be solved first in the bonding process.
Acrylic shadowless adhesive, which participates in the curing reaction by dissolving the acrylic and releasing the curing agent to achieve the bonding between the acrylics. From the physical and chemical point of view, it has the commonality of the above two adhesives; in terms of operability and bonding effect, it completely overcomes their disadvantages and has their advantages.
