Embodiment

[0047] Get the raw materials ready according to the proportioning in Table 1, and react in the reactor. First, press the rubber into small pieces with a tablet machine, put it into the active diluent, stir, and wait until the rubber is completely dissolved; then put the polyurethane acrylate, tackifier, and glutinous rice flour into the above solution according to the corresponding parts by mass, and put the reaction kettle The temperature rises to 60°C and stirs to obtain a uniform liquid phase (it takes 1 hour); then put in epoxy acrylic resin and stir until it is evenly mixed (it takes 30 minutes); add the initiator and curing agent and stir for 30 minutes, An environment-friendly adhesive for rapid bonding of an aluminum alloy and a PVC film is obtained. Stop stirring, and when the temperature of the reaction kettle drops to normal temperature, quickly bond the aluminum alloy and the PVC film with an environmentally friendly adhesive to fill, and pack it into a bottled glu...

Abstract

The invention discloses an environment-friendly adhesive for quickly adhering aluminum alloy and PVC thin film and preparation and application thereof. The environment-friendly adhesive comprises the following components: 10 to 30 parts of urethane acrylate, 5 to 40 parts of epoxy acrylate, 10 to 30 parts of rubber, 5 to 15 parts of viscosifier, 20 to 60 parts of reactive diluent, 2 to 5 parts ofglutinous rice flour, 0.2 to 1.5 parts of initiator and 0.2 to 1.0 part of curing agent. The environment-friendly adhesive has excellent adhesion performance on the aluminum alloy and PVC insulating thin film, has the adhesive force of the first level, and can be applied to high-temperature operating environment; and the cured adhesive film has higher softening point of over 80 DEG C. The mean value of the hardness of the cured adhesive film obtained by using the adhesive is between 70 and 75A; and the adhesive film cured has good hardness and toughness. The environment-friendly adhesive for quickly adhering aluminum alloy and PVC thin film and the preparation and application thereof have the advantages of simple preparation method, moderate cost, stable comprehensive performance of the obtained products, and great functions of energy conservation and emission reduction.

Description

technical field [0001] The invention belongs to the field of adhesive preparation, and in particular relates to an environment-friendly adhesive for rapid bonding of an aluminum alloy and a PVC film, as well as its preparation and application. Background technique [0002] High-strength aluminum alloy materials are mainly used in building doors and windows and steel structure parts, and are an important material commonly used in buildings. Before the existing aluminum alloy materials are put into use, a layer of silver-white coating is usually applied on the surface of the aluminum alloy by powder spraying or electroplating. A uniform oxide layer; also to prevent the surface of the aluminum alloy from being polluted by various oils and absorbing some other impurities. Coating the surface of aluminum alloy by powder spraying or electroplating will not only cause huge pollution, mainly the discharge of waste and waste liquid; moreover, the aluminum alloy material obtained in ...
