Abstract
The invention provides a reactive intermediate. The reactive intermediate can be used for preparation of a reactive macromonomer. A preparation method has the advantages of simplicity and convenience in operation, high yield and the like. The reactive macromonomer can improve the steric hindrance effect among cement particles, can effectively avoid an intercalation function of PEO (polyoxyethylene) side chains and has good clay resistance. A super-high early-strong polycarboxylate superplasticizer synthetized with the reactive macromonomer as a main raw material can promote the hydration function of cement and accelerate strength development of hardened cement and performs a super-high early-strength function; the problem of poor dispersion performance of existing PCEs (polycarboxylate superplasticizers) in the concrete containing clay can be effectively solved, representation and tests show that the super-high early-strong polycarboxylate superplasticizer synthetized with the reactive macromonomer as the main raw material has good dispersion performance for the concrete with or without the clay, and the dispersion performance of the PCEs in the concrete containing the clay is better than that of traditional PCEs.
Description
Technical field
The present invention relates to a kind of intermediate and polymeric monomer, be specifically related to a kind of active intermediate and surface-active macromonomer.
Background technology
In recent years, the R & D and manufacture of concrete admixture has tended to towards high-performance, pollution-free future development, and cement water reducing agent is that in concrete admixture, application surface is the widest, the one that usage quantity is maximum.The polycarboxylate water-reducer (PCEs) with combed molecular structure is made up of to the main chain of negatively charged ion polyethoxye (PEO) side chain graft usually, PEO side chain produces space steric effect between the cement granules being suspended in aqueous phase, by adjusting the molecular structure of PCEs, different objects can be reached, as slump retaining is good, water-reducing rate is high, cohesiveness is good, resistance to mud is good, in addition low cost, the advantage such as pollution-free, the research of polycarboxylate water-reducer has become the focus of domestic and international concrete admixture research and development.
The main raw material of poly carboxylic acid series water reducer has unsaturated acid, as maleic anhydride, toxilic acid and the polymerisable carboxylic acid such as vinylformic acid, methacrylic acid, the thiazolinyl materials such as polyalkenyl hydrocarbon, ether, alcohol, poly styrene sulfonate or ester and acrylate, ester, dihydroxy-benzene, acrylamide etc., synthetic method has the direct copolymerization of polymerisable monomer, polymerization Post functionalization method, in-situ polymerization and grafting etc. substantially.
The direct copolymerization of polymerisable monomer: this synthetic method is generally first prepare the pendant reactive polymeric monomer (being generally methoxy polyethylene glycol methacrylate-styrene polymer) with polymerization activity, then the monomer of certain proportioning is mixed, directly adopt solution polymerization and obtain finished product.This polymerization process, technique is simple, but prerequisite wants composite reactive polymerizable surface-active macromonomer, and the performance of surface-active macromonomer directly determines and affect the performance of the finished product polycarboxylate water-reducer.
Current China market mainly contains for the production of the active polymeric monomer of PCEs water reducer:
MPEG: poly glycol monomethyl ether
VPEG:4-hydroxy butyl vinyl ether Soxylat A 25-7
APEG: allyl alcohol polyethenoxy ether
HPEG: isobutene alcohol Soxylat A 25-7
TPEG: isopentenol polyoxyethylene ether
APEG is bar-shaped rigid structure, high to cement adsorptive capacity, and TPEG microtexture is star-shape polymer, has soft segment microtexture, few to cement adsorptive capacity.
APEG is the main raw material of synthesizing polycarboxylic acid high-performance water reducing agent, the advantages such as PCEs water reducer has good dispersity, volume is low, and water-reducing rate is high, adaptability is good of synthesis; Shortcoming is inferior suitability, and Slump Time losing of Large is large.HPEG and TPEG is the water reducer of raw material production, and water-reducing rate is more or less the same, but summer uses, and slump retaining gap is comparatively large, and cement adaptability is slightly poor.Use the PCE high performance water reducing agent of polyocarboxy acid that TPEG is main material production, production process equipment is simple, and slump-retaining and cement adaptability is better than HPEG, and shortcoming is starving.
Commonly PEO class side chain in PCEs water reducer structure, but PEO side chain is easy to the aluminosilicate laminated structure inserting clay, cause water reducer not to be adsorbed on cement particle surface, but define chemisorption with clay, thus reduce the comb voltinism energy of PCE.
When PCEs water reducer is applied in concrete, due to RCOO
-with Ca
2+ionization forms complex compound, reduces the Ca in solution
2+concentration, delays Ca (OH)
2form crystallization, reduce the formation of C-H-S gel, delayed the aquation of cement, PCEs water reducer has certain delayed coagulation usually.
Summary of the invention
The object of the invention is to overcome weak point that prior art exists and provide a kind of active intermediate and preparation method thereof, present invention also offers a kind of surface-active macromonomer and preparation method thereof.The cation quaternary ammonium salt PCEs water reducer synthesized by surface-active macromonomer of the present invention, owing to introducing cationic quaternary ammonium salt groups in the molecular structure, can hydrated cementitious be accelerated, accelerate the strength development of cement solidification and maturing, there is super hardening effect, reduce the susceptibility to clay simultaneously.
