Abstract
The invention discloses a kind of preparation method of town road center isolation railing, this method is using paper mill sludge as raw material, after sodium perchlorate's sterilization and surface modification treatment, using techniques such as classification drying, ball mill crushing and homogenizations, paper mill sludge is processing modified into composite filler, use fretting map technique that isolation railing is made by isolation railing stock mould by melting extrusion in composite filler after addition regenerated polythene, crosslinking agent and compatilizer.This method makes isolation railing after paper mill sludge is made into effectively processing, reduces making and the maintenance cost of isolation railing, saves beneficial to resource, reduces pollution of the paper mill sludge to environment, have larger social and economic benefit.
Description
Technical field
The present invention relates to a kind of preparation method of town road center isolation railing.
Background technology
Isolation railing there is irreplaceable status in urban transportation, its ensure traffic safety, prevent traffic accident,
Ensure to play a positive role in the coast is clear.Being generally insulated the making material of railing has PVC, steel pipe etc., the isolated column of PVC material
Bar impact resistance is poor, cracky, easy to aging, improves maintenance cost；The isolation railing of tube material need to be consumed beneficial to resource, and
Antirust and landscaping treatment need to be carried out to surface, such as zinc-plated antirust and color powder spray so that complex manufacturing technology, are greatly improved
Cost of manufacture.
And paper mill sludge is the discarded object of paper making process and has larger contaminative, larger people need to be spent
Power, material resources are handled it, to avoid the pollution to environment.Therefore paper mill sludge is turned waste into wealth, and is applied to isolated column
Preparing for bar is significant.
The content of the invention
The technical problems to be solved by the invention are to provide a kind of preparation method of town road center isolation railing, we
Method makes isolation railing after paper mill sludge is made into effectively processing, reduces making and the maintenance cost of isolation railing, saves beneficial
Resource, pollution of the paper mill sludge to environment is reduced, there is larger social and economic benefit.
In order to solve the above technical problems, the preparation method of isolation railing in town road center of the present invention comprises the following steps：
Step 1: using paper mill sludge as raw material, handled through two stage cylinder formula drying oven dehydration and drying, during which add sodium chlorate sterilization
And surface modification treatment so that paper mill sludge moisture content decreases below 10% from more than 80%, and kills except in paper mill sludge
Harmful bacteria；
Step 2: the paper mill sludge after dehydration and drying is crushed using ball mill, it is equal using wind-force flotation and double storehouses plansifter after crushing
Matter processing, paper mill sludge is formed fineness and be more than 200 mesh, and powder is smooth, quality is balanced, interface performance compound filling out well
Charge；
Step 3: composite filler, crosslinking agent and compatilizer are added in regenerated polythene is made raw material, its group after sufficiently mixing
It is divided into 60~65wt% of regenerated polythene, 30~35wt% of composite filler, 1.2~1.5wt% of crosslinking agent, 3~6wt% of compatilizer；
Step 4: raw material is made by isolation railing by isolation railing stock mould by melting extrusion using fretting map technique.
Further, the crosslinking agent is tri (propylene glycol) diacrylate or diethylene glycol diacrylate, the phase
Appearance agent is maleic anhydride/polyethylene graft copolymer.
Further, the drying temperature of the two stage cylinder formula drying oven is 130~300 DEG C.
Because the preparation method of town road of the present invention center isolation railing employs above-mentioned technical proposal, i.e., this method is with papermaking
Sludge is raw material, after sodium perchlorate's sterilization and surface modification treatment, is dried using classification, ball mill crushes and homogenization etc.
Technique, paper mill sludge is processing modified into composite filler, composite filler interior addition regenerated polythene, crosslinking agent and compatilizer
Isolation railing is made by isolation railing stock mould by melting extrusion using fretting map technique afterwards.This method makees paper mill sludge
Isolation railing is effectively made after processing, making and the maintenance cost of isolation railing is reduced, saves beneficial to resource, it is dirty to reduce papermaking
Pollution of the mud to environment, there is larger social and economic benefit.
Embodiment
The preparation method of isolation railing in town road center of the present invention comprises the following steps：
Step 1: using paper mill sludge as raw material, handled through two stage cylinder formula drying oven dehydration and drying, during which add sodium chlorate sterilization
And surface modification treatment so that paper mill sludge moisture content decreases below 10% from more than 80%, and kills except in paper mill sludge
Harmful bacteria；
Step 2: the paper mill sludge after dehydration and drying is crushed using ball mill, it is equal using wind-force flotation and double storehouses plansifter after crushing
Matter processing, paper mill sludge is formed fineness and be more than 200 mesh, and powder is smooth, quality is balanced, interface performance compound filling out well
Charge；
Step 3: composite filler, crosslinking agent and compatilizer are added in regenerated polythene is made raw material, its group after sufficiently mixing
It is divided into 60~65wt% of regenerated polythene, 30~35wt% of composite filler, 1.2~1.5wt% of crosslinking agent, 3~6wt% of compatilizer；
Step 4: raw material is made by isolation railing by isolation railing stock mould by melting extrusion using fretting map technique.
Preferably, the crosslinking agent is tri (propylene glycol) diacrylate or diethylene glycol diacrylate, the phase
Appearance agent is maleic anhydride/polyethylene graft copolymer.
Preferably, the drying temperature of the two stage cylinder formula drying oven is 130~300 DEG C.
The application surface of the composite filler obtained by this method is quite varied, has been sufficiently reserved fiber fines in paper mill sludge
With the material property of the composition such as calcium carbonate, as the extension product of additive, it can be improved on the basis of original technique is constant
Isolate the performance of railing, reduce product cost.This method is using paper mill sludge and regenerated polythene as raw material, by paper mill sludge system
Into composite filler, then environmental protection and the repeatable product utilized are produced after following process is handled, paper mill sludge is turned waste into wealth,
The comprehensive utilization of resource is realized, while production manufacturing process is pollution-free, effects of energy saving and emission reduction is notable.Manufactured isolation railing
It is easy to clean, exempt to paint, reduce maintenance cost, and the obtained isolation railing of this method is lighter than steel material, is readily transported, also drops
The low cost of transportation of product.
