Description
Technical field
The invention discloses a kind of composite sludge is non-burning brick, belong to building material technical field.
Background technology
Non-burning brick is to utilize flyash, cinder, gangue, mine tailings, residue of chemical industry or natural sand, tidal land under normal circumstances
Mud etc.（The one or several kinds of the above raw material）As primary raw material, a kind of novel wall material manufactured without high-temperature calcination,
It has been widely used in building trade.
The life and production waste generated to city is handled so that and water resource is recycled, but at sewage
Its a large amount of sludge generated therewith of reason factory's treated sewage do not obtain respective handling but or efficiently use, and often result in secondary to environment
Pollution.Such as the dragon's fountain sewage treatment plant of Zhuzhou, the total treating capacity of sewage is 100,000 ton per days, and wastewater treatment efficiency is up to standard, is passed through
Dragon's fountain sewage treatment plant processes the tail water of qualified discharge, can become neighbouring Donghu Park endlessly running water source, breed fish and pour
It fills all out of question.But byproduct --- the sludge of its generation, all the time using air storage, the smell is awful, sternly
Ghost image rings the environmental sanitation of surrounding area.Facing to the more more sludge of heap, the secondary pollution process problem and recycling of sludge
Comprehensive utilization urgent need solve.
The present inventor is by analyzing and researching to sludge caused by dragon's fountain sewage treatment plant, in conjunction with non-burning brick required original
Material and manufacture craft, carry out development test repeatedly, develop finally a kind of using the sludge of sewage treatment plant as primary raw material system
That makees is non-burning brick, and the non-burning brick intensity is high, durability is good, and the popularization and application of the technology will handle sewage treatment plant well
The secondary pollution problem of sludge, and comprehensive utilization of resources effectively is carried out to sludge.
Non-burning brick characteristic is that other any wall body bricks are no, with rational scientific formula, is added according to a certain percentage
Coagulator and chemical additives make granularity, humidity, the rational apparatus and process intensive treatment of mixability, reach best
Plastic state keeps brick body rapid curing by high pressure compression moulding, and the time is longer, and effect is better, and the practicability of brick is good, builds a wall
Shi Buyong impregnates, and appearance is neat.Since this kind of materials ' durability is good, dimensional standard, shape is complete, color and luster is uniform, have simple and unsophisticated
Natural appearance, can do dry wall can also do any external decoration.Therefore, be it is a kind of substitution clay brick it is extremely promising
Renewal product.
But current non-burning brick the problem of can not being further increased there is also mechanical property, it also needs further to study.
Invention content
The present invention solves the technical problem of：It is asked for what the non-burning brick mechanical property of tradition can not further increase
Topic, it is non-burning brick to provide a kind of composite sludge.
In order to solve the above-mentioned technical problem, the technical solution adopted in the present invention is：
A kind of composite sludge is non-burning brick, is made of the raw material of following parts by weight：
40~60 parts of sludge
20~30 parts of cement
8~10 parts of silicon ash
8~10 parts of flyash
15~20 parts of phenolic resin
10~20 parts of quartz sand
30~40 parts of water
10~20 parts of modified filler
5~8 parts of coupling agent
5~8 parts of hexamethylenetetramine
The non-burning brick preparation process of the composite sludge is：It is formed by raw material and weighs each component raw material, by sludge, cement, silicon ash,
Flyash, phenolic resin, quartz sand, water, modified filler, coupling agent and hexamethylenetetramine are stirred, injection molding, are stood, pressure
Type is made, demoulds, high temperature and pressure conserves, and natural curing is non-burning brick to get composite sludge.
The sludge be sewage from oil refinery handle secondary settling tank activated sludge, sewage treatment plants secondary settling tank activated sludge or
Any one in river sludge.
The cement is portland cement, any one in aluminate cement or sulphate aluminium cement.
The phenolic resin is phenolic resin 2123, any one in phenolic resin 2127 or phenolic resin 2130.
The quartz grain fineness number modulus is 2.3~2.6.
The preparation process of the modified filler is：By diatomite and hydrochloric acid in mass ratio 1：10~1：20 are stirred, mistake
Filter, washing, obtains single treatment diatomite；By single treatment diatomite and dopamine solution in mass ratio 1：10~1：20 stirrings are mixed
It closes, filtering obtains after-treatment diatomite；It counts in parts by weight, by 10~20 parts of after-treatment diatomite, 5~8 parts of sepiolites,
50~60 parts of water are stirred, and are concentrated under reduced pressure, dry, are obtained and are handled diatomite three times；Diatomite and positive silicic acid second will be handled three times
Ester in mass ratio 1：10~1：20 are stirred, and filter, freezing, obtain four processing diatomite；By four processing diatomite and pig
Oil in mass ratio 1：10~1：20 impregnate, and filtering obtains modified filler.
The coupling agent is aluminate coupling agent, any one in silane coupling agent or titanate coupling agent.
The beneficial effects of the invention are as follows：
The present invention by add modified filler, in preparation process, first, diatomite is impregnated through persalt, kill fall it is diatomaceous
Hole is widened, and is then impregnated with dopamine solution, is effectively improved diatomaceous absorption property, be conducive to later stage sepiolite
Fibre bundle can be fixed on inside diatomite, then passed through ethyl orthosilicate and impregnated and freeze, ethyl orthosilicate is fixed on silicon
It in diatomaceous earth, is finally coated with lard, in use, with the progress of hydrated cementitious, pH gradually rises in system, changes
For the property surface coated Hydrolysis of Lard of filler at glycerine, glycerine plays good lubricating action, avoids reuniting between modified filler,
Simultaneously so that the ethyl orthosilicate that inside is wrapped up is exposed, and ethyl orthosilicate is reacted with water, the poly silicic acid of generation, from
And so that the mechanical property of system gets a promotion, and at the same time, the sepiolite fibre beam part exposure of inside absorption so that modified
The roughness on filler surface is further promoted, so that mechanical snap is easily formed between modified filler, so that the power of system
Performance is learned further to be promoted.
