Description
technical field
The present invention relates to the manufacture of geo-grid, be specifically related to a kind of nano modification high-impact work grid and preparation method.
Background technology
Along with the development of geosynthetics industry, increasing geo-grid product has pushed market to, and the main competition of geo-grid is exactly product performance and Costco Wholesale competition.Because polypropylene geogrid field is extensive with use region, therefore geo-grid is required that it has multiple performance.But only realizing these performances by a kind of polymkeric substance is be difficult to realize, and therefore needs to carry out to geo-grid formula the inexorable trend that modification becomes this industry.Being a kind of general and effective means preparing fiber reinforcement in high performance material, strengthening fiber used and being generally glass fibre, carbon fiber etc.The resin tooth successful obtained by these fiber filled, can make the geo-grid of same size thinner.But after using glass fibre and carbon fiber, the tensile elongation of polymkeric substance has again very large decline, cause geo-grid to stretch very short, product weight per unit area rises, and production cost is increased on the contrary, is unfavorable for the object reaching cost degradation.
In geo-grid, add the fillers such as modified carbon black, acidproof, alkaline-resisting, corrosion-resistant and ageing resistance preferably can be made it have, improve resistance to impact shock and tensile strength.
Summary of the invention
The invention provides a kind of nano modification high-impact work grid and preparation method.The present invention by the raw-material modification of formula, thus obtains the geo-grid with advantages such as intensity are high, toughness is large, erosion resistance is strong.

The preparation method of described modified filler: a, take following component raw material by weight: calcium carbonate 70-80, kaolin 10-20, sodium polyacrylate 0.3-0.5, white oil 1-3, antioxidant 1010 0.1-0.3, stearic acid 0.2-0.4, concentration are sodium hydroxide solution 40-50, the tween 80 0.1-0.3 of 10-15%, barium stearate 2-4, aluminium hydroxide 5-6, triethanolamine borate 1-2; B, calcium carbonate, kaolin are joined sodium hydroxide solution, 20-30 minute is ground at 60-70 DEG C, then sodium polyacrylate, white oil, stearic acid are added wherein, continue grinding 5-10 minute, add tween 80, barium stearate continuation grinding 10-15 minute again, finally add the remaining components such as thanomin boric acid ester, at 75-80 DEG C, grind 20-35 minute, then through dehydration, dry, the obtained modified filler of screening.
The preparation method of described nano modification high-impact work grid, is characterized in that, comprise the following steps:
(1) by formula rate by PP resin, MLLDPE, maleic anhydride graft propylene, talcum powder, titanic acid ester, the strong prestige powder of nanometer, ZnO, antioxidant 1010, put in Banbury mixer, 120-140 DEG C of melting banburying, obtain banburying material A;
(2) after banburying material A and modified filler being mixed in proportion, drop in twin screw extruder hopper, extruded at lower than 215 DEG C of temperature by forcing machine again, melt is by three-roller calendar sheet forming, sheet material carries out punching through stamping machine, orifice plate, through being warmed up to 80 DEG C of-95 DEG C of back draft, namely obtains nano modification high-impact work grid.
The beneficial effect that the present invention obtains is:
The present invention is compared with common geo-grid, by PP resin, MLLDPE, maleic anhydride graft propylene mixing banburying, add the strong prestige powder of a small amount of nanometer, self-control modified filler can improve product mechanical property, particularly shock resistance improves greatly, eliminates the problem that common geo-grid fragility is large, easy to crack.
Geo-grid of the present invention, under same thickness, the tensile elongation of product improves 60%-90%; Single rib length improves 10%-55%; Shock strength improves 55%-75%.
