Abstract
The invention discloses a cold-resistant hot melt adhesive. The cold-resistant hot melt adhesive is prepared from the following raw materials in parts by weight: 7-10 parts of linear low-density polyethylene, 50-60 parts of American Dupont 560 (Ethylene-Vinyl Acetate), 2-5 parts of epoxy resin 828, 20-28 parts of rosin resin 138, 2-6 parts of modified heavy calcium carbonate, 1-2 parts of cashew nut shell oil, 0.5-0.7 parts of angelica oil, 8-10 parts of oxidized polyethlene wax and 2-4 parts of composite filler.
Description
Technical field
The invention belongs to binding agent field, relate in particular to a kind of cold-resistant hot melt adhesive.
Background technology
In recent years, the application of the novel materials such as matrix material and plastics on automobile made automobile stick with glue agent and the also sustainable growth of seal gum consumption, and wherein automotive upholstery is the field that tackiness agent consumption increases rapidly.The demand of automotive upholstery hot melt adhesive is more and more.
Summary of the invention
The object of this invention is to provide a kind of cold-resistant hot melt adhesive.
The present invention adopts following technical scheme to achieve these goals:
A hot melt adhesive, is characterized in that, it is that raw material by following weight parts makes:

The preparation method of modified heavy calcium carbonate is: get water-ground limestone, add again the clorafin that is equivalent to water-ground limestone weight 1-2%, the epoxy oleum lini of 1.2-2.8%, the Silane coupling agent KH550 of 1-1.5%, and appropriate amount of deionized water, under 800-900 rev/min, at 50-65 ℃, after stirring reaction 10-15 minute, take out, dry, obtain modified heavy calcium carbonate;
Compounded mix is made by the raw material of following weight parts: kaolin 15-20, neatly stone flour 12-14, aluminum oxide powder 2-4, borax 0.5-1, polypropylene glycol diglycidyl ether 0.2-0.4, titanium dioxide 1-2, calcium lignin sulphonate 0.1-0.2, dioctyl sebacate 1-2, oxidation inhibitor 626 0.8-0.9, polypropylene fibre 1-2, alcohol ether glucoside 0.3-0.5, trisodium phosphate 0.3-0.5, Sodium hexametaphosphate 99 0.3-0.5
The preparation method of described compounded mix is: preparation method soaks 8-10 hour by kaolin, neatly stone flour in clear water, takes out, dry, add again suitable quantity of water and borax, aluminum oxide, titanium dioxide, stir, then calcine 1-2 hour at 600-700 ℃, take out, cooling, adding 10-15% sodium hydroxide solution tune PH is 8.5-9.5, and ground slurry is to 400-500 order, add again hydrochloric acid soln and be adjusted to neutrality, dry, then mix with surplus stock, ground and mixed evenly and get final product.
Described a kind of cold-resistant hot melt adhesive, is characterized in that:
Preparation process is:
(1) linear low density polyethylene, compounded mix are put into blender and mixed;
(2) again epoxy resin 828, modified heavy calcium carbonate, cashew nut shell oil are put into blender and mixed;
(3) after again all the other raw materials being put into blender and mixing, granulation, cooling and pelletizing, obtain.
Beneficial effect of the present invention: raw materials of the present invention contains modified heavy calcium carbonate and compounded mix, each raw material consistency is good, and winter hardiness is good, and cohesive strength is high, and automotive upholstery surface adhesion woven fabric is used this hot melt adhesive bonding effect smooth.
