Abstract

The invention discloses a preparation method of a special high-strength hot melt adhesive for bonding glass, which comprises the following steps: providing 30-65% of raw material SIS; 2-20% of mineral oil; 1-5% of a stabilizer; 20-65% of terpene phenolic resin; the reaction kettle is heated, when an oil meter shows that the oil temperature reaches 180 DEG C, raw materials SIS, mineral oil and a stabilizer are sequentially and slowly added into the reaction kettle, terpene phenolic resin is added after all the added raw materials are melted, it is confirmed that all the raw materials are melted, a switch of a vacuum machine is turned on to extract air in glue liquid, and heat preservation is conducted on the reaction kettle; turning on a feeding switch of the reaction kettle, naturally cooling and packaging. The hot melt adhesive has the beneficial effects that the hot melt adhesive has quick adhesiveness, has a very good adhesion effect on glass, and is suitable for adhesion and fixation of glass products; moreover, the physical state of the prepared high-strength hot melt adhesive is changed along with the change of the temperature within a certain temperature range, the chemical characteristics are not changed, and the high-strength hot melt adhesive is non-toxic and harmless and belongs to an environment-friendly adhesive.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a preparation method of a high-strength hot-melt adhesive specially used for bonding glass. Background technique [0002] Hot melt adhesive is a kind of plastic adhesive. Its physical state changes with temperature within a certain temperature range, but its chemical properties remain unchanged. It is non-toxic and tasteless, and is an environmentally friendly chemical product. Because the product itself is solid, easy to pack, transport, store, solvent-free, non-polluting, and non-toxic; and it has the advantages of simple production process, high added value, strong bonding strength, and fast speed. Glass is a well-known difficult-to-bond material because of its smoothness. Usually, special glass glue is used to bond glass, but glass special glue is often inconvenient to operate because of its slow curing speed. Contents of the invention [0003] The purpose of the...
