Problems solved by technology

Due to the certain humidity in the room, the moisture in the air will be condensed when it touches the lower temperature glass plate, and condensation and frost will occur on the edge of the insulating glass, which will not only affect the appearance, but also cause damage to the sealing material.

[0035]

[0036]

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

[0038] The manufacturing method of the above-mentioned 5 examples is as follows: the first step is to heat the temperature of the reactor to 170°C-180°C, then add phenol-modified poly-a-methylstyrene resin, ethylene maleic anhydride copolymer, antioxidant Stir with agent 1010 for about 60 minutes; in the second step, reduce the temperature of the reactor to 155°C-160°C, add maleic anhydride grafted APAO and ethylene-methacrylic acid copolymer, stir and melt for about 70 minutes and pump Vacuum, the vacuum gauge pressure is between -0.06mpa and -0.09mpa; in the third step, the temperature of the reactor is kept at 155°C-160°C, adding poly-a-methylstyrene resin (AMS) to stir and vacuumize for 60 minutes, the vacuum gauge pressure Between -0.06mpa and -0.09mpa; after stirring evenly, the outlet is connected to a single-screw extrusion granulation system for underwater pellet cutting, dehydration, dryi...

Embodiment 1

[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 affected by the ambient temperature of the workshop, the opening time will not be enough.

Embodiment 2

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

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.

Description

technical field [0001] The invention relates to a hot-melt adhesive coated hollow glass warm edge strip and a manufacturing method thereof. Background technique [0002] Insulating glass is composed of two or more glass plates, the glass plates are separated by edge sealing system, and the middle is filled with gas. The glass plate can be ordinary flat glass, tempered glass or Low-E glass, which is selected according to the place where the insulating glass is used and the function it plays. The gas between the glass plates must be dry, which can be air, argon or other special gases, and molecular sieves are used to keep the gas dry. There are many types of edge sealing systems, mainly spacers (frames), sealants and molecular sieves. The spacer bar is between the two layers of glass, which plays the role of separating the glass plates, and seals the edges with sealant to make the glass bond together and prevent the gas in the layer from overflowing. When there are two flui...
