Description
Technical field：
The present invention relates to road dental calculus processing technique fields, and in particular to a kind of road dental calculus repairing reworked material and its bonding side
Method.
Background technology：
Road dental calculus refers to the boundary stone used in pavement edge, also referred to as curbstone (kerbstone) or kerb, curb.Road dental calculus is on road
On face distinguish driveway, pavement, greenery patches, isolation strip and road other parts boundary line, play ensure pedestrian, vehicular traffic peace
Effect complete and that guarantee pavement edge is neat.
Currently, road dental calculus is typically to be formed or cut using lithotome, Ru Huagang by normal concrete is prefabricated
Road dental calculus made of rock, marble.Since road dental calculus made of lithotome cutting is not only drawn materials, constructional difficulties, but also resource
It is limited, natural resources is destroyed, therefore be not widely used in recent years.Though but the road dental calculus made of normal concrete on the market
Right price is less than lithotome, but its raw materials for production processes made road dental calculus not only resistance to compression mainly with sand, stone, cement production systD
There are some potential safety problemss to pedestrian and vehicle for the notch occurred after intensity is low and broken.
Since there are security risks for waste and old ore, it is therefore desirable to be replaced to it, and be difficult to make by repairing method
Mend reaches original use intensity.And if waste and old ore directly discards the serious waste that will cause resource, is unfavorable for
Existing environmentally friendly machining based conception.

(5) road dental calculus is processed：Auxiliary material after super low temperature is stirred evenly with major ingredient, and is poured into road dental calculus mold
In, adhesive is repaired in damaged road dental calculus surface smear high intensity before pouring, is demoulded for 24 hours after pouring, then at 15-20 DEG C of environment
It is middle to conserve 28 days to get road dental calculus.
The flocculation aid is made of soil grade polyglutamic acid and N hydroxymethyl acrylamide, and preparation method is：It will be native
After earth grade polyglutamic acid and N hydroxymethyl acrylamide mixing plus water is completely dissolved, and adds potassium peroxydisulfate saturated aqueous solution,
And dilution heat of sulfuric acid regulation system pH value is added dropwise to 4-5, it is then heated to the reaction of reflux state insulated and stirred, is waited for after reaction
Gained mixture is sent into spray dryer, micro mist is made to get flocculation aid through micronizer in dry gained particle.
The soil grade polyglutamic acid, N hydroxymethyl acrylamide, potassium peroxydisulfate saturated aqueous solution mass ratio be 5-
10:5-10:0.5-1。
Short velveteen, marble powder, phosphate ester starch~natural plant gum copolymerization adhesive, polyoxyethylene in the auxiliary material composition
Alkene, 2 micelle of Nano-meter SiO_2, phosphate ester starch, activating agent and deionized water weight ratio be 1-2:15-18:3-4:3-4:2-3:
1-3:15-20。

Activating agent and deionized water are put into reaction kettle；
It is 500-600rpm to open and stir and control stir speed (S.S.), continues to stir 1-2h, above-mentioned raw materials is made all to mix；
Phosphate ester starch~natural plant gum copolymerization adhesive is put into reaction kettle, improves stir speed (S.S.) to 800-
1000rpm is added short velveteen and continues to stir 3-5h；
Period heats marble powder, 200-220 DEG C of high-temperature heating, constantly stir-fries in heating process；
Stop heating, marble powder is placed in reaction kettle, is stirred evenly, it is cooling, make material in reactor natural cooling
Auxiliary material is obtained to 35-40 DEG C.
The high intensity repairing adhesive includes two layers, and internal layer is cement, glue, magnetic fluid, aqueous mixtures, and outer layer is stone
Sand particle, calcium carbonate granule, resin binder part mixture.
The cement, glue, magnetic fluid, water weight ratio are:10：13：1：15；

The internal layer preparation method is, after cement is mixed with water, heating is in grume, glued magnetic fluid is added,
It stirs evenly；In use, being applied to damaged road dental calculus surface with hairbrush；
The outer layer preparation method is separately to heat quartz sand particle, calcium carbonate granule, resin binder；Resin
After adhesive heating, is smeared extruded on internal layer with hairbrush, quartz sand particle, the calcium carbonate granule after heating are sprayed at resin-bonding
In agent；
Dental calculus of building the road is poured, completion is damaged, and metal powder is sprinkled in seam crossing.
The beneficial effects of the invention are as follows：
(1) crushing and mouldability of the invention by waste and old ore activates, and realizes the regeneration of waste and old ore, avoids
Waste and old ore it is directly discarded caused by environmental pollution, while reducing the processing cost of new road dental calculus；And the cooperation for passing through auxiliary material
It uses, ensures the performance of made road dental calculus；
(2) present invention accelerates the resume speed of waste and old ore mouldability and carries waste and old ore by the use of flocculation aid
The recovery extent of mouldability, fully activation abandon the processability of road dental calculus；
