Abstract
The invention discloses a plastic manhole composite powder formula, which is composed of the following components of: by weight, 91-95% of linear low-density polyethylene resin, 3-3.9% of an anti-oxidant, 0.8-1.1% of a viscosity conditioning agent and 1.2-4% of a reinforcing agent. Composite powder formula is suitable for making an ultra-large plastic manhole, has excellent physical and mechanical properties (ring stiffness being greater than 8kN/m<2>; axial test pressure being greater than 60kN; and lateral test pressure being greater than 20kN), has no crack or deformation, and satisfies industry standards.
Description
Technical field
The present invention relates to a kind of plastic inspection well, especially a kind of ultra-large type, the compound powder formulation of HS
Background technology
The general well depth of prior art plastic inspection well is less than 1 meter, and maximum diameter is less than 650mm.Its composite powder that adopts is made up of high-density polyethylene resin, colour batch, lime carbonate.Its main drawback is that physical and mechanical property is poor, plastic is in light weight, the moulding volume is little, can't satisfy the requirement of super-large size plastic inspection chamber ME.
Summary of the invention
The object of the present invention is to provide the prescription of a kind of ultra-large type, high-intensity plastic inspection well specific complex powder.
Technical scheme of the present invention is: a kind of super-large size plastic inspection chamber composite powder prescription; Described composite powder prescription is made up of linear low density polyethylene resin, inhibitor, viscosity modifier, toughener, and wherein the shared weight percent of each component is respectively linear low density polyethylene resin and accounts for 91%-95%, inhibitor 3%-3.9%, viscosity modifier 0.8%-1.1%, toughener 1.2%-4%.
In preferred embodiment of the present invention, described inhibitor is a 2,6 di tert butyl 4 methyl phenol.
In preferred embodiment of the present invention, described viscosity modifier is a polyethylene wax.
In preferred embodiment of the present invention, described toughener is TEB 3K and nano-calcium carbonate.
The toughener that the present invention selects, wherein TEB 3K and nano-calcium carbonate weight ratio are 1: 1.
According to the invention is a kind of prescription of plastic inspection well specific complex powder; After adding various compositions in this compound prescription, be fit to make diameter at 3.5 meters, well depth reaches 9 meters plastic inspection well; Can reach good physical and mechanical property again, promptly ring stiffness is greater than 8kN/m
2More than, axial test pressure is greater than 60kN, and the side direction TP is greater than 20kN, and all crack-free or distortion are satisfied municipal drainage with plastic inspection well industry standard (CJ/T326-2010) requirement.
Embodiment
Set forth in detail in the face of the preferred embodiment of patent of the present invention down, thereby protection scope of the present invention is made more defining of clear and definite so that advantage of the present invention and characteristic can be easier to it will be appreciated by those skilled in the art that.
According to the invention is the prescription of a kind of ultra-large type, high-intensity plastic inspection well specific complex powder, and this prescription is made up of linear low density polyethylene resin, inhibitor, viscosity modifier, toughener, and each weight percent ratio of forming is:
The ratio of specific embodiment does
Can debug according to different ratios according to different demands.
Patent of the present invention is said to be the prescription of a kind of ultra-large type, high-intensity plastic inspection well specific complex powder; After adding various compositions in these plastics; This composite powder is had be fit to make diameter at 3.5 meters; Well depth reaches 9 meters plastic inspection well, can reach good physical and mechanical property again, and promptly ring stiffness is greater than 8kN/m
2More than, axial test pressure is greater than 60kN, and the side direction TP is greater than 20kN, and all the requirement of municipal drainage with plastic inspection well industry standard (CJ/T326-2010) satisfied in crack-free or distortion.
Embodiment of the present invention; But protection scope of the present invention is not limited thereto; Any those of ordinary skill in the art are in the technical scope that the present invention disclosed, and variation or the replacement that can expect without creative work all should be encompassed within protection of the present invention is divided into.Therefore, protection scope of the present invention should be as the criterion with the protection domain that claims were limited.
