The surface of homogeneous or heterogeneous objects connected together by chemical or physical force technology is called gluing, gluing bonding material used is called adhesive, also known as adhesive, bonding agent, commonly known as glue. Because the adhesive bonding can be applied to different materials, thickness, specifications and complex components of the connection, with a continuous stress distribution, light weight, simple operation, good performance and other advantages, so the rapid development and wide application, has become the adhesive bonding, welding, mechanical connection of one of the three major contemporary connection technology, and our lives are closely related. The following will be a detailed introduction to the adhesive.
Adhesive is a substance with good bonding properties, cured with sufficient strength, can be the same, two or more materials and components through the surface adhesion to make it close to each other bonded together, but also able to fill the gap. Adhesive is a generic term that includes a number of other glues, mastics, pastes, pastes, and so on. Adhesive can also be expressed as a natural or synthetic, organic or inorganic two types of substances to make two or more parts (or materials) connected together.
Most of our common adhesives are synthetic adhesives, composed of the main agent and additives, the main agent is also known as the main material, base material or adhesive, is a multi-component material, the basic adhesion, in order to meet the specific physical and chemical properties, but also need to add a variety of additives. Auxiliaries are curing agents, diluents, plasticizers, fillers, coupling agents, initiators, thickeners, antioxidants, polymerization inhibitors, stabilizers, complexing agents, emulsifiers, etc. According to the requirements and uses can also include components such as flame retardant, foaming agent, defoamer, coloring agent and mildew inhibitor. For example, in order to make the main agent to form a network or body structure, in order to increase the cohesive strength of the adhesive layer needs to be added to the hardener or vulcanizing agent; in order to accelerate the hardening or vulcanization needs to be added to the catalyst or vulcanizing agent; in order to reduce the rigidity of the adhesive layer to increase the toughness needs to be added to the plasticizer and so on.
Not any one substance can be used as an adhesive, the adhesive must meet the following requirements:
1. No matter what kind of form, it should present liquid state when coated.
2. Ensure that the surface of the object to be adhered to can be fully infiltrated.
3. Must be able to make the transition from liquid to solid state, the formation of a tough adhesive layer.
4. Have a certain strength after curing, can transfer stress and resist damage.
5. Be able to withstand a certain amount of time.
Adhesive can be directly several materials firmly bonded together, with the development of synthetic chemical industry, there are many types, according to the chemical composition to points, then, can be divided into the following kinds:
1. Acrylic adhesives, multiple curing methods, a variety of parts bonding, more rapid positioning and curing, more excellent bonding strength.
High performance acrylic adhesives. Unique performance and wide range of applications, designed for structural bonding, electronic wiring reinforcement, electronic components fixed sealing. With good adhesion, toughness, good weather resistance and other characteristics. A variety of different viscosity, hardness, color options, easy to apply, fast curing, improve assembly efficiency.
2. Polyurethane adhesive, in a variety of surfaces with strong adhesive force, the same or different materials bonding more firmly and reliably.
cham polyurethane adhesive series bonding and toughness can be adjusted, and has excellent bonding strength, temperature resistance, chemical resistance and aging resistance. It covers hot melt adhesives, reactive structural adhesives, solvent-based three-proof adhesives and other product types. For metal, rubber, glass, ceramics, plastics, wood, fabric, leather and other materials have excellent adhesive properties.
3. Epoxy adhesive, bonding strength and mechanical strength is particularly excellent, temperature resistance and chemical resistance is not uncommon, substrate applicability is equally wide.
According to the difference in product type, different products can be room temperature curing can be heated and fast curing, curing with very high bonding strength and mechanical strength, excellent temperature resistance, chemical resistance. Can be used for electronic parts and structural components of the bonding and fixation, sealing protection, device protection.
4. Mechanical silicon adhesive has good sealing and bonding properties, tolerance of weathering, low temperature to -60 ℃, high temperature to 200 ℃, it can be easily.
According to the different types of products, respectively, with excellent temperature resistance, insulation and other core properties, but also has good sealing and bonding properties. It is widely used for fixing reinforcement of electronic components, cavity sealing, waterproof protection, etc. It is also suitable for sealing, filling, bonding and encapsulation in high temperature applications, such as high temperature kitchen appliances, thermoelectrics, air purifiers.
Adhesives can be used in all aspects of daily life and production, such as epoxy structural adhesive can be used for electronic parts and fasteners bonding fixed, RTV silicone can be used for electronic components fixed reinforcement, PUR hot melt adhesive can be used for cell phone shell bonding.
