Problems solved by technology

[0003] Geotextiles are mainly synthetic fibers. In the current construction process, geotextiles need to be bonded with double-sided adhesives at the construction site or directly and simply covered. The existing technology uses double-sided adhesives to increase construction time and is cumbersome, and the bonding strength is poor. Direct coverage Rough workmanship and poor waterproof effect

[0039] The second object of the present invention is achieved by the following technical solutions: a method for preparing hot-melt adhesive for drainage boards, which specifically includes the following steps:

[0040] 1) Add polyisobutene (medium molecular weight polyisobutene with a molecular weight of 35,000, brand name HRD350 produced by Shandong Hongruida Company) and antioxidant into the kneader, and heat up to 135±5°C;

[0041] 2) Then add the formulated amount of rubber mixture, stir, and after the mixed system melts, add the formulated amount of EVA, set the speed at 30 rpm, and stir evenly for 20 minutes;

[0042] 3) Then put in the wax, tackifying resin and ultraviolet absorber of the formula amount in turn, and stir for 10 minutes;

[0043] 4) Finally add the mixture formed by mixing the remaining amount of polyisobutene and the coupling agent of the formulation amount, the molecular weight of the polyisobutene is a low molecular weight polyisobutene of 400, and the...

Abstract

The invention discloses a drain board hot melt adhesive and a preparation method thereof. The drain board hot melt adhesive is prepared from the following components in parts by weight: 20-50 parts of EVA, 5-20 parts of wax, 5-20 parts of polyisobutene, 1-5 parts of an antioxidant, 30-60 parts of tackifying resin, 1-5 parts of an ultraviolet absorbent, 0.3-3 parts of a coupling agent and 5-20 parts of a rubber mixture. The prepared hot melt adhesive for the drainage plate can be adaptive to bonding of geotechnical cloth and a plastic bottom plate, and is high in bonding strength and excellent in ultraviolet aging performance; the geotextile can be directly bonded in a workshop after the drain board is pressed, and the construction site process is simple.

Description

technical field [0001] The invention relates to a hot melt adhesive technology, in particular to a drainage board hot melt adhesive and a preparation method thereof. Background technique [0002] At present, the drainage structure is widely used. The drainage board is generally made of polyvinyl chloride (PVC) or polyethylene (HDPE) as the raw material. It is formed, and a geotextile is glued on the convex point to prevent the passage of soil particles, thereby avoiding the blockage of the drainage channel and making the drainage channel smooth. The traditional drainage method uses masonry tiles as the filter layer, and uses more pebbles or gravel as the filter layer to drain the water to the designated location. Using the drainage board to replace the cobblestone water filter layer for drainage can save time, labor and energy, save investment, and can also reduce the load of the building. [0003] Geotextiles are mainly synthetic fibers. In the current construction proces...
