Embodiment 1-7

[0021] The preferred formula composition and mass parts thereof of the present embodiment are as shown in Table 1 below:

[0022]

[0023] testing method

[0024] The colloid obtained by the proportioning of raw materials in this embodiment 1-7 is detected using the following method:

[0025] 1. The heat resistance test is carried out according to the relevant clauses of HG / T 3698-2002 EVA hot melt adhesive.

[0026] 2. Adhesiveness, apply the colloid on the outside of the wooden furniture, roll it twice with a 2KG roller, and test the peeling strength of the glue after taking it out.

[0027] 3. Weather resistance, apply the colloid on the outside of wooden furniture, and pass the Shore hardness tester after 1 hour.

[0028] The colloid performance parameter that embodiment 1-7 makes is as shown in table 2 below:

[0029]

[0030] Through the test of examples 1-7, it can be seen that the colloid obtained in the proportion of example 5 has better heat resistance, stro...

Embodiment 8-13

[0032] The preferred formula that above-mentioned experiment obtains adds polyethylene wax and maleic anhydride wax to graft, and its specific mass parts are as shown in 3:

[0033]

[0034] testing method

[0035] The colloid obtained by the ratio of raw materials in this embodiment 8-13 is detected using the following method:

[0036] 1. Adhesiveness, apply the colloid on the outside of the wooden furniture, roll it twice with a 2KG roller, and test the peel strength of the glue after taking it out.

[0037] The colloid performance parameter that embodiment 8-13 is made is as shown in table 4 below:

[0038]

[0039] Based on the tests in the above examples, the raw material of this furniture edge banding glue is preferably prepared from the following ingredients in proportion by mass: EVA-UL7711, 10 parts; EVA-654, 30 parts; EVA-638, 30 parts; polyolefin, 3 parts; Tackifying resin, 18 parts; polyethylene wax, 2 parts; maleic anhydride wax grafted, 2 parts. 18 parts...

Abstract

The invention belongs to the technical field of hot melt adhesives, and particularly relates to a furniture edge sealing glue and a preparation method thereof. The furniture edge sealing glue is prepared from, by mass ratio, 25 parts of EVA, 7 parts of APAO, 12 parts of POE, 34 parts of tackifying resin, 27 parts of fully hydrogenated C9 and 5 parts of fully hydrogenated rosin. The preparation method for the furniture edge sealing glue includes mixing the above-mentioned raw materials at 150 DEG C to obtain a colloidal mixture, and performing underwater pelleting production through a twin-screw extruder. The furniture edge sealing glue is good in aging resistance and yellowing resistance, has a fast curing speed, good toughness and good bonding performance at low temperature, and is suitable for causing a PE film wrapping a sucker to be bonded to a carton.

Description

technical field [0001] The invention belongs to the technical field of hot melt adhesives, and in particular relates to a furniture edge sealing adhesive and a preparation method thereof. Background technique [0002] In the contemporary society with continuous economic development, people have a higher pursuit of quality of life, and the decoration style is constantly changing. All materials need to be edge-banded to achieve protection of furniture and overall aesthetics. In the past, hot melt adhesive was only used as a bonding medium, that is, to glue the PVC edge banding to the panel section. However, on the one hand, the cost of using traditional hot-melt adhesives for edge sealing is high; on the other hand, due to the rigidity of PVC edge banding strips, it is easy to cause edges and deviations during operation due to colloidal problems, and it is also easy to increase the unevenness of the treated furniture. Pass rate. [0003] The Chinese invention patent with th...
