Embodiment 1

[0018] First, heat the reactor to 140°C, then add 12kg of SX-105 wax into the reactor and stir. After the SX-105 wax is completely dissolved, add 40kg of 1#5100C5 hydrogenated petroleum resin and stir again. After 1#5100C5 hydrogenated petroleum Add 0.6kg antioxidant 1010, 0.4kg antiaging agent A (antiaging agent A is produced by Tianjin Labo Auxiliaries Co., Ltd.), 14kg amorphous polymer after the dissolution of resin (1#5100C5 hydrogenated petroleum resin is produced by Exxon, USA). Olefin APAO750, heat and stir and vacuumize, keep the temperature of the material at about 145 ° C, after all the components are dissolved, then add 33kg of amorphous polyolefin APAO708, stir and vacuumize, until all components become transparent and uniform until viscous liquid is reached, then stop stirring and discharge while hot to obtain hot melt adhesive. Take 100g of the prepared hot melt adhesive and place it in a 200ml beaker, place it in an oven at 190°C, and observe the color, viscosit...

Embodiment 2

[0022] First, heat the reactor to 150°C, then add 20kg of SX-105 wax into the reactor for stirring, after the SX-105 wax is completely dissolved, add 54kg of 0#5100C5 hydrogenated petroleum resin (0#5100C5 hydrogenated petroleum resin is produced by the United States Kesen production) stir again, after 0#5100C5 hydrogenated petroleum resin dissolves, add 0.5kg antioxidant 1010, 0.5kg antioxidant first, 10kg amorphous polyolefin APAO8640, heat and stir and vacuumize, keep material temperature at 145 At about ℃, after all the components are dissolved, add 15kg of amorphous polyolefin APAO708, stir and vacuumize until all the components become transparent and uniform viscous liquid, then stop stirring and discharge while hot. That is, a hot melt adhesive is obtained. Take 100g of the prepared hot melt adhesive and place it in a 200ml beaker, place it in an oven at 190°C, and observe the color, viscosity, and degree of carbonization after 1, 2, and 3 days. The experimental data a...

Embodiment 3

[0026] First heat the reactor to 145°C, then add 5kg of SX-105 wax into the reactor for stirring, after the SX-105 wax is completely dissolved, add 60kg of 5000C5 hydrogenated petroleum resin and stir again, after the 5000C5 hydrogenated petroleum resin is dissolved, add 0.9kg of antioxidant 1010, 0.1kg of antiaging agent A, 14kg of amorphous polyolefin APAO8640, heating and stirring and vacuuming, keeping the temperature of the material at about 145°C, after all the components are dissolved, add 20kg of amorphous polyolefin APAO708 , Stir and vacuumize until all components become transparent and uniform viscous liquid, then stop stirring and discharge while hot to obtain hot melt adhesive. Take 100g of the prepared hot melt adhesive and place it in a 200ml beaker, place it in an oven at 190°C, and observe the color, viscosity, and degree of carbonization after 1, 2, and 3 days. The experimental data are shown in Table 3 below:

Abstract

The invention discloses an amorphous poly alpha olefin (APAO) hot melt adhesive and a preparation method thereof. The APAO hot melt adhesive comprises the following components in percentage by weight:25-60% of amorphous polyolefins, 30-60% of tackifying resin, 5-20% of wax, 0.1-1% of an antioxidant and 0.1-1% of an anti-aging agent. The APAO hot melt adhesive provided by the invention has good thermal stability and good solvent resistance, special adhesive using equipment is not needed, and the cost is low.

Description

technical field [0001] The invention relates to the field of adhesives, in particular to an APAO hot melt adhesive and a preparation method thereof. Background technique [0002] Hot melt adhesive is a solvent-free thermoplastic solid adhesive. Within a certain temperature range, its physical state changes with temperature, but its chemical properties remain unchanged. It does not contain solvents, is non-toxic and tasteless, and is an environmentally friendly chemical product. The hot melt adhesive is solid at room temperature, and melts into a liquid state when heated to a certain temperature. It can be used by spraying, rolling and scraping, and is solid when it is cooled to room temperature. After cooling and solidification, it will produce good bonding effect. It is easy to use and has a wide range of uses. It has been widely used in many domestic industries. [0003] At present, hot-melt adhesives for woodworking mainly include solvent-based adhesives, EVA hot-melt a...
