Embodiment 1

[0033] Polypropylene carbonate resin (GeenPolTM, available from SK energy Co.) having a weight average molecular weight of 30,000 g / mol, to which was added 10 parts by weight (phr) of hydroxymethyldioxolane ketone (methoxy tri-ethylene glycol) ether, and adding 20 parts by weight of phenol-modified terpene resin (DS105, available from DRT Co.) with a softening point of 95° C. °C. Mix in a Brabender mixer for 5 minutes. A sheet having a thickness of 0.7 mm was produced by hot pressing, and various dumbbell-shaped samples were produced, followed by measurement of tensile strength and elongation thereof. In addition, if figure 1 As shown, at a temperature of 140°C, a sample with a size of 25mm10mm was bonded between the wood and the PVC sheet for 1 minute, and then the adhesion force was measured by UTM. Furthermore, two PVC sheets were bonded to each other under the same conditions, and the adhesion force therein was measured. Set the test speed to 50mm / min. The results obta...

Embodiment 2

[0035] By the same method, using bis(triethylene glycol methyl ether) glutarate instead of using hydroxymethyldioxolanone (methoxytri-ethylene glycol) ether as the extender in Example 1 Plasticizers for the preparation of hot melt adhesive compositions.

Embodiment 3

[0037] The samples were prepared and evaluated by the same method, but without using the plasticizer in Example 1.

Abstract

Provided is a polypropylene carbonate based resin composition used as a hot melt adhesive. In detail, the present invention is to provide a composition of the hot melt adhesive having high adhesion to a polar surface of the polypropylene carbonate resin based hot melt adhesive and adhesion to a non-polar surface. The composition of hot melt adhesive according to the present invention has excellent compatibility between raw materials so as to have a completely uniform phase, thereby increasing cohesive energy as the adhesive and having the excellent adhesion to the polar or non-polar surface.

Description

technical field [0001] The present invention relates to a hot-melt resin composition having adhesion to polar surfaces and non-polar surfaces, which utilizes modified terpene resins to obtain adhesion to polar surfaces and to supplement adhesion to non-polar surfaces, At the same time, polypropylene carbonate resin is used as a hot-melt resin to achieve low-carbon production in the process of life cycle assessment (LCA) (analysis of carbon emissions) of hot-melt adhesives. Background technique [0002] Hot-melt adhesives are hot-melt adhesives, and their use as environmentally friendly adhesives is gradually increasing due to the low emission of volatile organic solvents. Recently, in terms of protecting the environment, efforts to prevent global warming while preventing emissions of volatile organic compounds that are harmful to humans have become common practice. As part of a worldwide effort, people are asked to use resins with low CO2 emissions, ie low life cycle assess...
