polyurethane adhesive for dry laminating - Introduction
Polyurethane adhesive for dry composite is a commonly used adhesive with the following properties:
1. Polyurethane adhesive has good adhesion properties and can form a firm bond strength on the surface of different materials.
2. It has excellent heat resistance and weather resistance, and can maintain stable adhesive performance under high temperature and harsh environment.
3. It has high elasticity and can withstand a certain degree of deformation and vibration without breaking.
4. Polyurethane adhesive has high tensile strength and shear resistance, and is suitable for bonding composite materials with high strength requirements.
Polyurethane adhesives for dry compounding are widely used, and common application areas include:
1. Automobile manufacturing: used for bonding automobile body parts and windshields.
2. Construction Engineering: used for bonding and packaging of metal, glass, stone and other materials.
3. Electronic appliances: used for electronic component packaging and circuit board fixed bonding.
4. Aerospace: used for bonding and repair of aircraft structures.
The method of preparing a polyurethane adhesive for dry compounding can be achieved by the following steps:
1. The polyurethane prepolymer and crosslinking agent are mixed and stirred according to a certain proportion.
2. Add the right amount of solvent or diluent, so that the adhesive has the appropriate fluidity.
3. It is necessary to add fillers, stabilizers, additives, etc. according to specific requirements to improve the performance of the adhesive.
4. Stir the mixture to make the components evenly dispersed.
5. Finally, the adhesive is cured and hardened in a dry environment by adding vacuum exhaust and curing agent.
in the use of dry composite with polyurethane adhesive need to pay attention to safety matters:
1. Avoid direct contact with skin and eyes. If you accidentally touch the skin, please rinse immediately with plenty of water and seek the help of a doctor.
2. During use, it should be fully ventilated to avoid inhaling the volatiles of the adhesive.
3. Polyurethane adhesives are mostly flammable substances. Pay attention to avoid fire and high temperature environment to prevent fire or explosion.
4. Storage should be sealed, avoid direct sunlight and humid environment.
5. Please read the safety instructions of the product carefully before use and operate according to the instructions on the instructions. If in doubt, please consult a professional for advice.
