Abstract

The invention discloses an enhanced and toughened water reducing agent which is characterized by being prepared by mixing the following raw materials in parts by weight: 46 to 50 parts of FDN-I high-efficient water reducing agent, 1 to 2 parts of aluminium hydroxide, 0.4 to 1 part of sodium fluosilicate, 0.1 to 1 part of cinerite, 0.5 to 1 part of ammonium persulfate, 0.1 to 0.6 part of iso-tridecanol polyoxyethylene ether, 0.3 to 0.6 part of butoxyethyl acetate, 1 to 2 parts of barium stearate and 0.3 to 1 part of tackifier. The water reducing agent has good adaptability in various cement and concrete admixtures, and can be used for improving the strength of concrete so as to improve the performance of a finished product.

Description

A kind of enhancing toughening type water reducer

Technical field

The present invention relates generally to a kind of water reducer, relates in particular to a kind of enhancing toughening type water reducer.

Background technology

Water reducer refers under concrete workability and cement consumption permanence condition, can reduce mixing water amount, improve concrete strength; Or under workability and intensity permanence condition, save the admixture of cement consumption.The very large shortcoming of existence that water reducer used has now, such as raw-material bad adaptability, retarding effect is bad, and therefore poor water retention property etc. are produced high performance water reducer and are necessary.

Summary of the invention

The object of the invention is just to provide a kind of enhancing toughening type water reducer.

The present invention is achieved by the following technical solutions:

An enhancing toughening type water reducer, it is mixed and to be formed by the raw material of following weight parts:

FDN-I high efficiency water reducing agent 46-50, aluminium hydroxide 1-2, Sodium Silicofluoride 0.4-1, volcanic ash 0.1-1, ammonium persulphate 0.5-1, different tridecanol polyoxyethylene ether 0.1-0.6,2-Butoxyethyl acetate 0.3-0.6, barium stearate 1-2, tackifier 0.3-1;

Described tackifier are to be made by the raw material of following weight parts:

Styrene-butadiene latex tackiness agent 20-30, nano-sized carbon 2-3, jade powder 1-2, wilkinite 2-3, rosin 3-5, Oil of Eucalyptus 1-2, tetramethylolmethane 2-3;

Above-mentioned tetramethylolmethane is heated to 160-165 ℃, add jade powder, wilkinite, 400-600 rev/min of dispersed with stirring 10-14 minute, adds nano-sized carbon, ball milling 3-5 minute, to after rosin heating fusing, add, fully mix, finally add styrene-butadiene latex tackiness agent, fully ball milling, cooling, obtain described tackifier.

Advantage of the present invention is:

Water reducer of the present invention and various cement and concrete admixture have good adaptability, can improve concrete intensity, improve end properties.

Embodiment

Embodiment 1

An enhancing toughening type water reducer, it by following weight parts (kilogram) raw material mix and to form:

FDN-I high efficiency water reducing agent 50, aluminium hydroxide 2, Sodium Silicofluoride 0.4, volcanic ash 0.6, ammonium persulphate 0.5, different tridecanol polyoxyethylene ether 0.6,2-Butoxyethyl acetate 0.6, barium stearate 1, tackifier 0.3;

Described tackifier are to be made by the raw material of following weight parts:

Styrene-butadiene latex tackiness agent 30, nano-sized carbon 2, jade powder 1, wilkinite 3, rosin 3, Oil of Eucalyptus 2, tetramethylolmethane 2;

Above-mentioned tetramethylolmethane is heated to 165 ℃, adds jade powder, wilkinite, 600 revs/min of dispersed with stirring 10 minutes, add nano-sized carbon, ball milling 5 minutes, by adding after rosin heating fusing, fully mixes, and finally adds styrene-butadiene latex tackiness agent, fully ball milling, cooling, obtains described tackifier.

Performance test:

Water-reducing rate: 26.2%;

Bleeding rate: 43%;

Air content: 2.3%;

Time of coagulation is poor :+503min.

Volume of the present invention is the 1-2% of cement consumption, and in identical water cement ratio situation, more than can making concrete slump raising 15cm, mobility increases considerably.
