Abstract
A geotechnical reinforcing grate is composed of polyethylene 85-92%, polypropylene 1.5-3.5%, pigment 0.2-0.4%, antioxidant 0.3-0.9%, and glass fiber 6-10%. This product can maintain its origina lshape even under 160 deg. C. does not age fro a long period, high in tensile strength and corrosion resistant. It is an ideal construction material for high way, railway, airfield, water conservancy, architecture, etc.
Description
The present invention relates to a kind of composition of macromolecular compound, especially a kind of be major ingredient with the polyethylene, be used to make New Building Materials---the composition of fiber reinforced grating for earth engineering.
Fiber reinforced grating for earth engineering is a kind of novel plastic building materials that are used for geotechnological construction projects such as highway, railway, airport, water conservancy, building.During construction, fiber reinforced grating for earth engineering is placed under pitch or the cement surface, can avoid soil erosion, improve stress distribution, prevent surface settlement, keep building surface long-term smooth as excellent as before.Existing fiber reinforced grating for earth engineering is a major ingredient with polyethylene or polypropylene usually, wherein adds an amount of look mother and oxidation inhibitor.The ubiquitous problem of this class fiber reinforced grating for earth engineering is that shock resistance, high thermal resistance are relatively poor, thereby is difficult to satisfy the requirement of high quality construction level.It is fundamental component with the polypropylene that the Chinese patent " a kind of polypropylene toughness-increasing modified material and preparation method thereof " that application number is 95116527.5, the day for announcing is 96.6.26 discloses a kind of, adds the toughness-increasing modified material of 5-20% polyethylene, 0.1-0.2% dispersion agent, 0.1-0.3% oxidation inhibitor, 0.005-0.015% surface-modifying agent.Make fiber reinforced grating for earth engineering with this material, though shock proof problem can be resolved, under the comparatively high temps situation, fiber reinforced grating for earth engineering is yielding, the aged problem still exists.Therefore, construction quality, still the engineering life-span all is subjected to certain restriction, is difficult to reach the ideal effect.
The objective of the invention is to: the problem at above-mentioned current material exists proposes a kind of composition material that can significantly improve the fiber reinforced grating for earth engineering resistance to elevated temperatures.
The composition of the manufacturing fiber reinforced grating for earth engineering that the present invention proposes contains polyethylene, polypropylene, look mother, oxidation inhibitor, also contain glass fibre, content ratio with the weight percent meter each component is: polyethylene 85-92%, polypropylene 1.5-3.5%, look female 0.2-0.4%, oxidation inhibitor 0.3-0.9%, glass fibre 6-10%.
Owing in composition material, added an amount of glass fibre, therefore the fiber reinforced grating for earth engineering of making is under the situation of Specifeca tion speeifications such as the original forming technology of basic maintenance, shock resistance, resistance to elevated temperatures obviously improves, even temperature is up to 160 ℃, also can keep original shape, not aging for a long time.In addition, the tensile strength and the erosion resistance that contain the glass fibre fiber reinforced grating for earth engineering also are significantly improved, and achieve many things at one stroke.Thereby for guaranteeing that geotechniques such as highway, railway, airport, water conservancy, building build the construction quality of facility and created extremely beneficial condition work-ing life.
The invention will be further described below by embodiment.
Make a kind of when can be used for the netted fiber reinforced grating for earth engineering of regular hexagon that bituminous pavement lays, 1000kg polyethylene, 25kg polypropylene, the brown look mother of 3kg, 8kg 1010 oxidation inhibitor and 90kg glass fiber pellets are evenly mixed together, by weight percentage: polyethylene 88.81%, polypropylene 2.22%, look mother 0.27%, oxidation inhibitor 0.71%, glass fibre 7.99% need not other and adds composition.Again compound is added in the hopper of fiber reinforced grating for earth engineering specific equipment, through heating, fusion, the discharging of equipment, draw in the net, cooling, setting treatment, make finished product.Through check, this fiber reinforced grating for earth engineering can be indeformable under 180 ℃ temperature, not aging, can satisfy 150 ℃ of construction requirements that dissolve bituminous pavement fully, and having solved in the past, the road surface is difficult to guarantee and keep smooth problem.
