Abstract

The invention relates to a coating hot melt adhesive for hollow glass warm edge strips and a manufacturing method of the coating hot melt adhesive. The technical solution is that the coating hot meltadhesive for the hollow glass warm edge strips comprises the following components, in parts by weight: 10-30 parts of maleic anhydride grafted APAO, 10-20 parts of an ethylene-maleic anhydride copolymer, 10-30 parts of an ethylene-methacrylic acid copolymer (EMA), 10-20 parts of poly alpha-methyl styrene resin (Ams), 20-30 parts of phenol modified poly alpha-methyl styrene resin, and 0.2-0.5 partof an antioxidant 1010. The coating hot melt adhesive provided by the invention has excellent bonding performance, can bind with PP and PVC stainless steel sheets at the same time, and has a wide application temperature range and a fast initial adhesion speed; and the method provided by the invention has the characteristics of a simple process and convenient preparation.

[0035]

[0036]

[0037] The data in the table are all parts by weight.

[0038] The manufacturing method of the above five embodiments is: in the first step, the temperature of the reactor is heated to 170°C-180°C, and then phenol-modified poly-a-methylstyrene resin and ethylene maleic anhydride copolymer are added, and antioxidant Agent 1010 was stirred for about 60 minutes; in the second step, the temperature of the reactor was lowered to 155℃-160℃, and maleic anhydride grafted APAO and ethylene-methacrylic acid copolymer were added. The melting time was about 70 minutes and pumped. Vacuum, the pressure of the vacuum gauge is between -0.06mpa~-0.09mpa; in the third step, keep the temperature of the reactor at 155℃-160℃, add poly-a-methylstyrene resin (AMS), stir and vacuum for 60 minutes, the pressure of the vacuum gauge Between -0.06mpa~-0.09mpa; after mixing evenly, the discharge port is connected to the single-screw extrusion granulation system for underwater pelletizing, dehydration, drying, packaging and inspection.

[0039]

[0040] The test results of the above five embodiments are as follows:

Example Embodiment

[0041] Example 1: The content of ethylene maleic anhydride copolymer is small, and the peel strength of PP and PVC is acceptable; the curing time just meets the requirements, but the opening time will be insufficient due to the influence of the workshop environment temperature.

Example Embodiment

[0042] Example 2: The content of ethylene maleic anhydride copolymer increases, and maleic anhydride grafted APAO increases; the peel strength of PP increases, the peel strength of PVC decreases, and the viscosity increases, which cannot meet the technical requirements.
