Abstract
The invention discloses a kind of comprehensive polycarboxylate water-reducer of muting sensitive sense, the composition of described polycarboxylate water-reducer and the raw material composition of parts by weight：15~40 parts of 30~60 parts of polycarboxylic acids solution, 20~30 parts of isopentene group polyoxyethylene ether, 30~70 parts of acrylic compounds polycarboxylate water-reducer, 10~30 parts of hydroxy-ethyl acrylate, 40~90 parts of collapse protective poly-carboxylic acid water reducing agent and sustained-release polycarboxylic water reducer.Water-reducing rate height, the effect that function of slump protection is good, volume sensitiveness is low can be reached, while production cost is greatly lowered.
Description
Technical field
The present invention relates to a kind of comprehensive polycarboxylate water-reducer of muting sensitive sense, belong to technical field of concrete additives.
Background technology
The polycarboxylate water-reducer sold on domestic market mainly has the high class of water reducing type and collapse protection type two.High water reducing type
Polycarboxylate water-reducer is because with higher water-reducing rate, its addition ratio is more sensitive, and concrete fluidity loss is very fast, to reality
Engineer applied brings certain difficulty.Collapse protective poly-carboxylic acid water reducing agent function of slump protection is preferable, but water-reducing rate is typically than relatively low, logical
Chang Yaoyu water reducer compounding uses, the high performance concrete of particular/special requirement is not suitable for it.For water-reducing rate is high, function of slump protection is good,
The synthesis of the low comprehensive polycarboxylate water-reducer of volume sensitiveness is domestic at present less, has the polycarboxylate water-reducer of identity function
Use supplied mainly by import, therefore cost is high, uneconomical.
The content of the invention
In view of the above-mentioned problems of the prior art, the present invention provides a kind of comprehensive polycarboxylate water-reducer of muting sensitive sense, subtract
Water rate, slump retaining and volume sensitiveness etc. are above commercially available prod, and cost is far below commercially available prod.
To achieve these goals, the technical solution adopted by the present invention is：A kind of comprehensive polycarboxylate water-reducer of muting sensitive sense,
The composition and parts by weight of described water reducer are polycarboxylic acids solutionPart, isopentene group polyoxyethylene etherPart, acrylic compounds polycarboxylate water-reducerPart, hydroxy-ethyl acrylatePart, the poly- carboxylic of collapse protection type
Sour water reducerPart and sustained-release polycarboxylic water reducerPart.
Further, described polycarboxylic acids solution is made up of the raw material of following parts by weight：AEOPart, acrylic acidPart, hydrogen peroxidePart, catalystPart and waterPart.
Further, described collapse protective poly-carboxylic acid water reducing agent includes the raw material of following parts by weight：Unsaturated polyoxyethylene
Ether polymeric monomerPart, acrylic acidPart, acrylic ester monomerPart, cross-linking monomerPart, chain turns
Move agentPart, initiatorPart.
Further, described unsaturated APEO polymeric monomer is allyl polyglycol ether or the poly- second of methacrylic
Glycol ethers, molecular weight is between 1000~2400.
Further, described initiator is dibenzoyl peroxide, the hexadecyl ester of dicetyl peroxydicarbonate two and the carbon of peroxidating two
Sour dihexyl, the catalyst are the mixture that vitamin C, Ge(SO) and amion acetic acid propyl ester are obtained by the ﹕ 2.5 of 1.5 ﹕ 2.
Compared with prior art, beneficial effects of the present invention are：Water-reducing rate, slump retaining and volume sensitiveness of the present invention etc.
Commercially available prod is above, improves the heat decomposition temperature of comprehensive polycarboxylate water-reducer, while significantly reduces production cost.
