Abstract
The invention discloses a kind of corrosion resistant ecological restoration materials for preventing and treating depletion, each constituent mass percentage composition is: high density polyethylene(HDPE) 83-94%, polymeric amide-6:3-10%, compatilizer: 2-4%, photostabilizer 0.4-1%, metal passivator 0.1-1% and black masterbatch 0.5-1%, by blended through homogenizer for above raw material, parallel dual-screw extruding machine extruding pelletization forms.The present invention makes high density polyethylene(HDPE) and polymeric amide fully compatible by using compatilizer, increases the mechanical property of material, improves the resistance to chemical corrosion of material.Capture simple interpolation oxidation inhibitor cause material mechanical performance to decline and improve under mechanical property, the difficulty that chemical resistance declines.Achieve the conventional concrete material that alternative conventional concrete material difficulty of construction is large, cost is high, long in time limit and the polythene material that mechanical property is low, chemical resistance is poor at present.
Description
Technical field
The present invention relates to a kind of corrosion resistant ecological restoration materials for preventing and treating depletion.
Background technology
Before the nineties in 20th century, the slope vegetation protection in the construction such as railway, road, hydro project, general adopt spreads the bank protecting method such as grass seeds bunch planting or trench sowing, turfing, hollow six rib brick grass plantings more.Through the development in more than 10 years, spray seeding technique has been widely used in the engineering slope protection such as the highway of China different areas, railway and dykes and dams.1993, China introduces earth working material grass planting bulkhead tech, civil engineering field and plastics business tie-up subsequently, develop various earth working material product, as three-dimension vegetative net, geo-grid, geonet, geotechnical grid etc., in conjunction with grass planting technology, apply in the slope greening of the engineerings such as railway, highway, water conservancy.Adopt polythene material more.But polythene material in the past due to mechanical property poor, be often difficult to produce a desired effect.
For the vegetative protection of slight slope inferior and rock slope, current studies in China is more.Prior art relatively successfully has following a few class: eco-concrete material, polythene material.
Eco-concrete material is domestic main products of controlling soil erosion at present.But its technical matters is complicated, engineering cost is high, the construction period is long, seriously governs the process of domestic improvement desertification and soil erosion.
Polythene material is the type material of China's civil engineering field and plastics business tie-up exploitation.Lower, the resist chemical performance of polythene material mechanical property own is poor can not meet a lot of bank protection field, the requirement of the higher wind-force of opposing rank.Alternative Traditional Ecological concrete material can't be reached from performance.
Summary of the invention
Based on above weak point, the present invention discloses a kind of corrosion resistant ecological restoration materials for preventing and treating depletion, and object is to substitute the existing eco-concrete material that construction costs is high, the construction period is long being widely used in bulkhead tech.Overcome current polythene material for protecting the problem that the fields such as base, retaining engineering and radical cure Desertification can not meet the resist chemical characteristic of strong mechanical performance and excellence in geologic hazard district ecological recovery, slope reinforcement, construction work.
For achieving the above object, the technical solution adopted in the present invention is: a kind of corrosion resistant ecological restoration materials for preventing and treating depletion, and each constituent mass percentage composition is as follows:
High density polyethylene(HDPE): 83%-94%,
Polymeric amide-6:3%-10%,
Compatilizer: 2%-4%,
Photostabilizer: 0.4%-1%,
Metal passivator: 0.1%-1% and
Black masterbatch: 0.5%-1%.
Wherein:
Described high density polyethylene(HDPE) molecular weight is 40000-100000;
Described compatilizer is maleic anhydride grafted polyethylene percentage of grafting is 4%-10%;
Described photostabilizer is:
P-t-butylphenyl salicylate (TBS),
Salicyl salicylic acid diplosal to phenol A ester (BAD),
Octabenzone (UV-531),
Poplar acid to octyl octylphenyl (OPS) or
2-hydroxyl-4-positive 12-alkoxy benzophenone (UV-1200);
Described metal passivator is:
N, N '-bis-[3-(3 ', 5 '-di-t-butyl-4 '-hydroxy phenyl) propionyl] hydrazine,
N, N '-two benzylidyne ethanedioyl two hydrazine or
N, N '-bis-(3-methoxyl group-2-naphthoyl) hydrazine.
The invention has the beneficial effects as follows:
The present invention adds by using the rational proportion of compatilizer, makes polyethylene and polyamide blended modification reach technical requirements, increases the mechanical property of material, improve the resistance to chemical corrosion of material.Capture simple interpolation oxidation inhibitor cause material mechanical performance to decline and improve under mechanical property, the difficulty that chemical resistance declines.Well improve the mechanical property of polythene material, thus improve material resistance to chemical corrosion, obtain high performance corrosion-proof ecological restoration materials.Under reaching control depletion situation, short construction period, construction costs are low, the effect of excellent material performance.
