Abstract
The invention relates to an efficient environment-friendly concrete preservative, which comprises the following components in portion by weight: 10 to 18 portions of various benzoic acids and boric acids, 20 to 40 portions of silica fume, 20 to 35 portions of alkalis; 35 to 50 portions of ethanolamine, and 15 to 20 portions of active components. The preservative can be widely applied to various building materials, especially to concrete and cement, and is reliable in rust prevention and corrosion resistance and good in environmental indexes. The preservative has the advantages of containing no mineral oil, containing no nitrite, chromate and the like harmful to human body, adapting to compressive strength (50 MPa in general) of actual requirements, improving strength, durability and heat resistance and meeting the requirements for high-performance concrete, along with no toxicity, no stimulation, no pollution, good construction performance, high dimensional stability, less shrinkage and no cracking in the hardening process.
Description
Technical field
The present invention relates to a kind of industrial concrete antiseptic agent.
Background technology
In skeleton construction, because design, construction and selection are improper, and the use of carboniogenesis, environmental pollution, change cryosel, physics and chemical actions such as external force collision, microbiological corrosion, much can not reach predicted life and wreck, therefore bring the waste of the property damage and the energy, resource.The too early destruction that the corrosion of concrete structure invar muscle causes concrete structure has become the essential factor that influences weather resistance and intensity.Up to the present; people have proposed the multiple method that prevents the concrete corrosion; for example increase thickness of concrete cover, add sanitas and make it become high performance concrete, concrete surface coating etc., wherein add sanitas, obtained to use widely as a kind of economical and practical method.But current preservative efficacy on the market is single, compound use then action effect reduces greatly, and most on the market sanitas all has certain pollution and toxicity to environment, and room air is had certain influence, is unfavorable for production operation personnel's physical and mental health and ecotope development.
Summary of the invention
For solving the problem that prior art exists; the inventor is through for many years practice; finally work out a kind of efficient environment-friendly concrete preservative; this product chemistry stable in properties, thermostability is also good, and it is convenient to preserve; its preservative effect is remarkable; have the particularly characteristics of weather resistance and good strength of overall target, and production process technology is complete, energy consumption is low.
The technology contents of efficient environment-friendly concrete preservative of the present invention is described below:
A kind of efficient environment-friendly concrete preservative, it is that ratio is formulated by weight by following compositions:
Multiple benzoic acids and boric acid 10-18 weight part;
Silicon ash 20-40 weight part;
Alkali matter 20-35 weight part;
Ethanolamines 35-50 weight part;
Activeconstituents 15-20 weight part.
Described benzoic acids comprises phenylformic acid, hydroxy-benzoic acid, o-toluic acid, and the mass ratio of phenylformic acid, hydroxy-benzoic acid, o-toluic acid, boric acid is 2: 1: 1: 0.5.
Described alkali matter comprises sodium hydroxide, yellow soda ash, salt of wormwood, water glass; Sodium hydroxide, yellow soda ash, salt of wormwood, water glass form by balanced mix.
Described ethanolamines comprises Monoethanolamine MEA BASF and diethanolamine, and the mass ratio of Monoethanolamine MEA BASF and diethanolamine is 3: 1.
Described activeconstituents comprises phenylformic acid monoethanolamine and ammonium benzoate, and the mass ratio of phenylformic acid monoethanolamine and ammonium benzoate is 2: 1.
When described efficient environment-friendly concrete preservative volume is concrete quality 5-10%, best results.
The method for making of described efficient environment-friendly concrete preservative is: benzoic acid derivative is mixed with alcohol amine compound, be preheated to 50 degrees centigrade, add activeconstituents and alkali matter then, mix to dissolving, add the silicon ash at last and get final product.
Because the handiness of this preservative substance formula composition and content, this product also can require according to client's difference and the market trend, with the prescription improvement for good metal cutting agent inhibiter etc.
Compared with prior art, the invention has the beneficial effects as follows:
This product can be widely used in various material of construction, especially is applied among concrete and the cement, and its rust-preventing characteristic, erosion resistance are reliable, and Environmental indicators is good.Do not contain mineral oil, do not contain harmful nitrite, chromic salt etc., nontoxic non-stimulated, pollution-free, improve simultaneously the technical indicator and the economic target of material of construction such as concrete largely, had good construction performance, high volume stability, contraction diminishes, do not ftracture in the process of setting, adapt to the actual ultimate compression strength that requires, be generally 50MPA, improve intensity and weather resistance and thermotolerance, satisfy the requirement of high performance concrete.
Part producing raw material of the present invention is an industry byproduct, be applied to solve industrial attached product handling problems among the new prescription of this compound benzoate, and realize the utilization of waste material maximization, meet current Green Chemistry, the requirement of efficient chemistry adapts to the trend that energy-conserving and environment-protective are produced.Preservative effect of the present invention is 2-4 a times of common sanitas, has prolonged the persistence of concrete work-ing life and security.This product consumption is few, and is effective, considerable benefit on Financial cost.
