Silicon powder 20~40%.
Specifically, acid polyethylene, also referred to as polyethylene or polyvinyl resin, polyethylene (polyethylene, abbreviation PE) are
A kind of aggregated thermoplastic resin obtained of ethylene.It industrially, also include the copolymer of ethylene and a small amount of ±-alkene.Poly- second
Alkene is odorless, nontoxic, feel ceraceous, and with excellent resistance to low temperature (minimum to use reachable -100~-70 DEG C of temperature), chemistry is steady
It is qualitative good, it is resistant to the erosion of most of soda acids (intolerant to the acid with oxidizing property).Common solvent, water imbibition are not dissolved under room temperature
Small, electrical insulating property is excellent.
The present invention uses the reason of acid polyethylene is as reinforcing agent, mainly since it includes 1, high impact properties, especially
It is in low temperature environment, impact strength reaches much higher value instead.2, service life is greatly improved in high-wearing feature.3, thermophilic
Property is wide: can work under Complex Temperature environment for a long time.
Further, polycarboxylic acids dehydragent (Polycarboxylate Superplasticizer) is that a kind of high-performance subtracts
Aqua is one of cement concrete utilization cement dispersants.It is widely used in highway, bridge, dam, tunnel, high level to build
The engineerings such as build.
Polycarboxylate water-reducer product can be divided into two major classes according to the difference of its backbone structure: one kind is with acrylic acid or first
Base acrylic acid is main chain, is grafted the polyethers of different side chain lengths.Another kind of is long using maleic anhydride as main link branch difference side chain
The polyethers of degree.
Polycarboxylic acids dehydragent overcomes some drawbacks of conventional water reducing agents, with volume is low, function of slump protection is good, concrete is received
Shrinkage is low, adjustability is strong on molecular structure, high performance potentiality are big, outstanding advantages of not using formaldehyde in production process.
Polycarboxylic acids dehydragent designs effective molecular structure according to the dispersion cement mechanism of action due to being truly realized,
With ultra-dispersed type, concrete slump loss can be prevented without causing obvious slow setting, higher plasticizing effect is played under low-dosage
Fruit, mobility retentivity is good, cement adapts to that freedom degree in wide molecular configuration is big, synthetic technology is more, the leeway of high performance is very big,
It is significant to concrete reinforcing effect, concrete shrinkage can be reduced, the technical performances feature such as harmful substance contents are extremely low imparts mixed
The outstanding construction workability of solidifying soil, good strength development, excellent durability, have good comprehensive technical performance advantage and
Environmentally friendly feature meets the needs of modernization concrete works.
The polycarboxylic acids dehydragent is DH-4004 polycarboxylic acids dehydragent.The water-reducing agent is more suitable for as the present invention
Reinforcing agent raw material, do not only reach water-reducing effect, while being also able to cooperate acid polyethylene and silicon powder, improve enhancing compression strength
Performance.
Silicon powder is a kind of nontoxic, tasteless, free of contamination inorganic non-metallic material.Have good temperature tolerance, acid-alkali-corrosive-resisting,
The excellent performances such as thermal coefficient is high, high insulation, low bulk, stable chemical performance, hardness are big.Fineness is micro- less than 1 in silicon powder
Rice accounts for 80% or more, and average grain diameter is at 0.1~0.3 micron, specific surface area are as follows: 20~28m2/g.Its fineness and specific surface area
About 80~100 times of cement, 50~70 times of flyash.SILICA FUME can the intergranular hole of filling concrete, while and water
Change product and generates gelinite.
In the concrete, mortar and refractory material casting material of cement base, suitable silicon powder is mixed, can be played the role that
1, resistance to compression, anti-folding, impervious, anti-corrosion, shock resistance and wear-resisting property are significantly improved.2, there is water conservation, prevent isolation, bleeding, substantially
Reduce the effect of concrete pumping resistance.3, significantly extend the service life of concrete.4, the landing of jetting cement and castable is greatly lowered
Ash improves single jetting thickness.5, product compression strength is improved.6, have effects that about 5 times of cement, in ordinary concrete and low cement
Application can reduce cost in castable, improve durability.7, it effectively prevent that concrete alkali-aggregate reaction occurs.8, casting type fire resisting is improved
The compactness of material.That is, being added to after silicon powder in the present invention, dregs compression strength of building block can not only be improved, together
When can also improve in other respects.
Further, the mesh number of the silicon powder is 1000~1200 mesh, in this way, the granular size of silicon powder is more moderate, and
Granular size is stablized, and can guarantee that product compression strength is maintained in claimed range.
Further, the dregs compression strength of building block reinforcing agent, by mass percentage, comprising:
Acid polyethylene 22~28%；
Polycarboxylic acids dehydragent 42~48%；
Silicon powder 25~35%.
Above-mentioned specific formula, obtained dregs compression strength of building block reinforcing agent to the improvement effect of compression strength more
It is good.
Further, the dregs compression strength of building block reinforcing agent, by mass percentage, comprising:
Acid polyethylene 25%；
Polycarboxylic acids dehydragent 45%；
Silicon powder 30%.
Above-mentioned more specific formula, obtained dregs compression strength of building block reinforcing agent to the improvement effect of compression strength more
It is good.
The present invention also provides a kind of preparation methods of dregs compression strength of building block reinforcing agent as described above comprising step
It is rapid:
Each component is weighed in proportion, a point stirring is mixed under room temperature, obtains the enhancing of dregs compression strength of building block after mixing evenly
Then agent dispenses.
In the present invention, first weigh each raw material in proportion, then each raw material is stirred, stirring be under normal temperature conditions into
Row, can impact to avoid to material property in this way, after fully mixed, obtain final dregs compression strength of building block
Reinforcing agent.
Further, mixing time is 20~40 minutes.Mixing time is too long, and material performance can be degenerated, and is not achieved most
Good effect, and mixing time is too short, raw material is difficult to play synergistic effect, and each raw material only individually plays a role, and is difficult to mix
Uniformly, it so currently preferred mixing time is 20~40 minutes, to make each raw material influence each other, maximally plays respective
Performance.
Further, the revolving speed of stirring is 60~80rpm.Speed of agitator is too fast, and the property of raw material can change, stirring
Obtained product can not play original performance, and speed of agitator is excessively slow, and raw material is unable to fully mix, so currently preferred revolving speed
It is 60~80rpm.
In following embodiment, the mesh number of the silicon powder is 1100 mesh, and the polycarboxylic acids dehydragent is preferably DH-4004
Polycarboxylic acids dehydragent.
