Description
Technical field
Diminishing agent method is prepared the present invention relates to one kind, it is more particularly to a kind of to prepare efficient diminishing using TGIC accessory substances
Agent method.
Background technology
Triglycidyl isocyanurate (TGIC) is the curing agent of powdery paints, because it has good weatherability, heat steady
Set, good mechanical performance, yellowing resistance is excellent and is widely used.Coatings industry " 13 " development plan is come out of the stove《Planning》Refer to
Go out, coating yield increases calculating by average annual 5%, by 2020, coating industry total output is estimated to rise to 22,000,000 tons of left sides
It is right.TGIC is the main coating of main existing application market, in medical science, moulds material, the aspect such as adhesive and coating, TGIC
There is the more and more extensive market demand so that the yield of TGIC accessory substances is consequently increased, its production process TGIC
Nearly ten thousand tons of the byproduct of 10% or so of yield cannot be utilized as discarded object, serious harm environment.Now also there is proposition TGIC
The utilization of accessory substance.Such as Tian Zhihong et al. is proposed TGIC accessory substances are modified using urea, TDI, then with poly- third
Olefin(e) acid ester emulsion is mixed to get a kind of paper-plastic stick adhesive（《Chemistry and bonding》In May, 2010）；Wang Yu proposes to utilize
TGIC accessory substances prepare composite elasticizer and are mixed into thermosol can be with reduces cost.（《HeFei University of Technology》
In April, 2012）；Wang Hui proposes to utilize TGIC accessory substance synthesizing water-solubility PURs《(Chemical Industry and Engineering Society of China year in 2015
Can collection of thesis》2015）.Although TGIC accessory substances propose some above-mentioned Application ways, but are not applied to actual production
In.
In recent years, with the high speed development of concrete industry, the research and development of concrete admixture are also gradually goed deep into, as mixing
Concrete indispensable " the 6th component ", and achieve good engineering effort.Pu Dehong is pointed out as at present using the most
Extensive concrete admixture --- water reducer, is also constantly alternating, and its performance improves constantly the (patent No.：1009-0825
(2015) 30-0105-03.) water reducer refer under concrete workability and cement consumption permanence condition, can reduce mix use
Water, raising concrete strength;Or under workability and intensity permanence condition, save the additive of cement consumption.Existing market
Above conventional several water reducers are：Lignin sulfonic acid sodium salt water reducer, naphthalene series high-efficiency water-reducing agent, aliphatic high-efficiency water reducing agent, ammonia
Base acid high efficiency water reducing agent, high-efficiency water-reducing agent of poly-carboxylic acid etc..Ma Qikun points out water reducer from lignosulfonates system, naphthalene system, trimerization
The course of the development such as cyanamide system, sulfamate system, polycarboxylic-acid, water-reducing rate also increases to 40% or so from 8%（The patent No.：
1674-6066. 2014. O1. 007.）.
Lignosulfonates based water reducer：Ligno-sulfate based plasticizer be by paper mill spent pulping liquor it is sulfonated, spray drying
One of byproduct obtained after being processed etc. operation, it is cheap, widely used mainly as plain edition water reducer, with medium journey
The water-reducing rate of degree.With the development of high-efficient high performance water reducer, lignin sulfonate water reducer can not increasingly meet people
Requirement.Such water reducer can show serious retardation phenomenon when addition is larger, and occur in use a large amount of
Sediment, has a strong impact on the intensity and endurance quality of concrete.Other wood working process is different, and species is different, in lignin
Toxic and harmful substance have to the performance of water reducer and have a strong impact on, its diminishing efficiency is only 8%-13% or so.Lignin
Based water reducer still has larger occupation rate of market due to its cheap, environment-friendly characteristic, but is mainly used in coagulation
Soil nature can less demanding occasion（The patent No.：1674-6066. 2014. O1. 007.）.
Naphthalene water reducer：China successfully produces naphthalene water reducer in the 80's of 20th century, and is widely used in public affairs
The engineerings such as road, bridge, railway, power station, dam, skyscraper, tunnel, as second generation high efficiency water reducing agent.Naphthalene water reducer
Main component is the condensation product of the sulfonate with formaldehyde of the homologue of naphthalene or naphthalene, as a kind of non-air-entraining water-reducing agent be it is current I
Application surface most one of maximum kind of wide, yield in state's high efficiency water reducing agent.The moderate dosage of naphthalene water reducer is cement quality
0.5% ~ 1.0%, water-reducing rate is that the d intensity of 10.0% ~ 25.0% concrete 28 improves more than 20%.With production
Process is simple is ripe, there is significant early strong, enhancing effect, not bleed, to Slow setting time to the effect of reinforcing bar non-corroding, to concrete
The features such as influenceing small, is that the current output of China is maximum, uses most wide high efficiency water reducing agent.But mixed during naphthalene water reducer application
Solidifying soil collapses, and loss is very fast, and the adaptability with cement is poor, also there are many deficiencies in engineer applied, general by changing
Feed postition compounds the measures such as other additives and is improved.In addition, many naphthalene water reducer stability are poor, to concrete
Condense hardness and durability influence is larger, and in process of production using raw materials such as the concentrated sulfuric acid, formaldehyde, the pollution to environment is tight
Weight, greatly limit the application and development of naphthalene water reducer（The patent No.：1674-6066. 2014. O1.
007.）.
Poly carboxylic acid series water reducer：In recent years, a kind of new high efficiency water reducing agent-poly carboxylic acid series water reducer is increasingly subject to
Extensive concern both domestic and external.The engineer applied of polycarboxylate water-reducer increasingly increases.Polycarboxylate water-reducer is that a kind of molecular structure is in
The anionic surfactant of pectination, is characterized on its main chain with the stronger active group of multiple polarity, while side
Then with the hydrophilic active group that substantial amounts of strand is more long on chain.Tang Jianjun points out the dispersibility of such water reducer by strong
Electrostatic repulsion is together decided on steric hindrance, and because volume is low, that water-reducing rate is up to 45%, Slump Time losing of Large is small, can carry
High concrete volume stability and durability, obvious isolation, excreting water phenomenon are not had, and concrete appearance color is homogeneous（Patent
Number：1007-1865(2015)16-0140-02）.For preparing high-flowing concrete, self-leveling concrete, self-compaction coagulation
Soil, shimizu finish concrete are extremely advantageous, but also have certain limitation, and following point is likely encountered in production of constructing：No
Same polycarboxylate water-reducer is different from the compatibility of cement and stronger to the selectivity of defoamer, air entraining agent, it is possible to cause institute
After mixed concrete hardening there is very big difference in intensity and setting time, and the hair of poly carboxylic acid series water reducer is constrained to a certain extent
Exhibition, most important is exactly expensive high-efficiency water-reducing agent of poly-carboxylic acid, and the cost of engineering will be increased considerably to limit it and promote and answered
With.
