Summary of the invention
In order to overcome above-mentioned technical problem, the purpose of the present invention is to provide a kind of high intensity HDPE bellows material and
Preparation method, prepared HDPE bellows have excellent wearability, thermal stability, and ageing-resistant performance feature improves
The overall mechanical properties and stability of material.
The present invention prepares filler after being acidified attapulgite using dilute hydrochloric acid processing by the formula of its filler slurry of change
Lotion can remove the impurity being distributed in attapulgite duct, increase its specific surface area, and obtained filler slurry not only can be with
Effectively attapulgite's surface is made to organise, moreover it is possible to improve dispersion degree of the filler between polyethylene, so as to improve material
Overall mechanical properties and stability, solve traditional HDPE bellows material non-refractory, crushing resistance is weak, impact resistance
The disadvantages of insufficient.
Surfactant refers to fixed hydrophilic lipophilic group in the present invention, can align on the surface of solution,
It enables to prepared material surface to have more smooth feeling, solves that material surface is more coarse, not enough beautiful disadvantage.
Its large specific surface area of the copper nanoparticle prepared in the present invention, can preferably scatter in polymer backbone, mention
Interconnection degree between high polymer skeleton, solves between polymer that cohesion is weaker, improves the entirety of polymer
Stability.
Modified flame-retardant agent prepared by the present invention, flame retardant property is good, and in comparative experiments, polymer material can be improved
Ignition point, solve the lower disadvantage of polymer ignition point.

Concave convex rod original soil is clayed into power, with appropriate dilute hydrochloric acid solution impregnate 5~10 hours after, remove filtrate, spend from
Filtered after sub- water washing, it is sufficiently 10~20 hours dry that filter cake is put into 80~100 DEG C of baking oven, be put into Muffle furnace 400~
500 DEG C calcine 2~3 hours, be cooled to room temperature, clay into power, obtain it is attapulgite modified, the present invention in attapulgite is used
Filler slurry is prepared after dilute hydrochloric acid processing acidification, the impurity being distributed in attapulgite duct is can remove, increases its specific surface
Product, obtained filler slurry not only effectively can make attapulgite's surface organise, moreover it is possible to improve filler between polyethylene
Dispersion degree solves traditional HDPE bellows material not so as to improve the overall mechanical properties and stability of material
The disadvantages of high temperature resistant, crushing resistance is weak, and impact resistance is insufficient；
18 carbamides will be saturated to be added in the beaker for filling dehydrated alcohol, successively add attapulgite modified, stearic acid
Calcium and surfactant, 50~60 DEG C stirring in water bath 1~2 hour, obtain filler slurry, surfactant refers to tool in the present invention
There is fixed hydrophilic lipophilic group, can be aligned on the surface of solution, enable to prepared material surface more smooth
Sense, solves that material surface is more coarse, not enough beautiful disadvantage；
(2) copper nanoparticle the preparation method is as follows:
Polyvinylpyrrolidone and polyethylene glycol are dissolved into the beaker for filling deionized water, in 60~70 DEG C of water-bath items
After being stirred 1~2 hour under part, until being sufficiently mixed uniformly, adds copper oxide particle and obtain suspension after mixing completely；
Ammonium hydroxide is slowly added dropwise in suspension to after forming colloidal solution, it stirring 1~2 hour will to being sufficiently mixed uniformly
Mixed solution pours into reaction kettle, is put into 180~200 DEG C of 1~2d of reaction of baking oven, takes out reaction kettle, is cooled to room temperature, is taken out
Filter, and it is put into 80~100 DEG C of baking oven sufficiently drying 10~15 hours, it clays into power, obtains copper nanoparticle, prepared in the present invention
Its large specific surface area of copper nanoparticle, can preferably scatter in polymer backbone, improve mutual between polymer backbone
Contiguity, solves between polymer that cohesion is weaker, improves the overall stability of polymer.
(3) modified flame-retardant agent the preparation method is as follows:
Aluminium-hydroxide powder and sodium aluminate are successively added in the beaker for fill deionized water and are sufficiently mixed uniform 1~2
After hour, aluminum hydroxide slurry is obtained；
A small amount of aminopropyl trimethoxysilane is added in slurries, is stirred 1~2 hour under 60~70 DEG C of water bath conditions,
To being sufficiently mixed uniformly, mixed solution is put into 80~100 DEG C of baking oven sufficiently drying 10~15 hours, grind into powder obtains
Modified flame-retardant agent, the present invention prepared by modified flame-retardant agent, flame retardant property is good, and in comparative experiments, polymer can be improved
The ignition point of material solves the lower disadvantage of polymer ignition point；
