Abstract
The present invention provides a kind of corrosion protection cement grinding aid and preparation method thereof, it is characterized in that, it is mixed by following components in percentage by weight: the water of 34.5%-45.5%, the Nacl of 6.5%-7.5%, the anhydrous sodium sulphate of 5.5%-6.5%, the sodium lignin sulfonate of 2.8%-3.2%, the triethanolamine of 14%-18%, the molasses of 1.8%-2.2%, remaining is additive.The present invention is free of sodium nitrite, and toxicity is faint and has good corrosion resistance.
Description
Technical field
The present invention relates to the field of building materials, in particular to a kind of corrosion protection cement grinding aid and preparation method thereof.
Background technique
Cement grinding aid is a kind of chemical addition agent for improving cement grinding effect and performance, can significantly improve cement platform
When yield, each age strength of cement, improve its mobility, prevent steel reinforced concrete erosion.Anti-erosion anti-corrosion is added in cement
Agent can make cement concrete have the superperformances such as salt resistance class ion erosion, the destruction of freeze thawing resistance circulation and highly resistance infiltration, and mixed
Solidifying soil aseptic applications are easy, do not need special construction technique.
Sodium nitrite is usually added into conventional cement grinding aid, people are because sodium nitrite is in cement using sodium nitrite
It can play the role of in grinding aid certain against corrosion.Although sodium nitrite itself is not carcinogen, sodium nitrite connects
The explosion of organic matter easy firing is touched, if generation sodium nitrate can react with oxygen by being exposed in air accidentally, with oxidisability, and is had
The friction of machine object or impact energy cause to burn or explode, and have toxicity.And sodium nitrite can also generate nitrous under certain condition
Amine has carcinogenicity.It can be seen that sodium nitrite has more virulent property, when serious can also threat to life, to cause security risk.
Summary of the invention
Technical problem to be solved by the invention is to provide a kind of, and the anticorrosive and toxicity without sodium nitrite is significantly faint
Corrosion protection cement grinding aid and preparation method thereof.
It is as follows that the present invention solves technical solution used by above-mentioned technical problem:
A kind of corrosion protection cement grinding aid of the present invention, it is mixed by following components in percentage by weight: 35%-
45% water, the Nacl of 6.5%-7.5%, the anhydrous sodium sulphate of 5.5%-6.5%, the sodium lignin sulfonate of 2.8%-3.2%,
The triethanolamine of 14%-18%, the molasses of 1.8%-2.2%, remaining is additive.The triethanolamine that the present invention is added is more traditional
Sodium nitrite toxicity significantly reduces, and is easier to store, and triethanolamine has corrosion resistance, moreover it is possible to prevent the poly- of crushing process powder
Collection and positice ground effect, improve the mobility and loading density of cement, reach preferable cement milling effect, and can reduce powder
The power consumption of broken machine.
Further, the additive is the dodium thiosulfate that the additive is 2.8%-3.2%, the urine of 3.8%-4.2%
Element, the compound hydramine of 14%-18%, the glycerol of 2.5%-3.5% can interact with triethanolamine and help each component in water
It gradually and is slowly discharged in mud grinding process, cement is effectively prevent to corrode, to improve cement grinding effect.
Further, water 40%, Nacl 7%, anhydrous sodium sulphate 6%, dodium thiosulfate 3%, urea 4% are wooden
Plain sodium sulphate is 3%, triethanolamine 16%, and compound hydramine is 16%, and glycerol 3%, molasses 2% effectively prevent cement
Corrosion, preferably raising cement milling effect.
A kind of preparation method of corrosion protection cement grinding aid of the present invention, which comprises the following steps:
In 16-32 degrees Celsius of environment, water, Nacl, anhydrous sodium sulphate, dodium thiosulfate, urea, sulfomethylated lignin are sequentially added according to sequencing
Sour sodium, triethanolamine, compound hydramine, glycerol, molasses, one component of every addition make to next component after completely dissolution, is added
Each component preferably plays a role, and cement is effectively prevent to corrode, preferably raising cement milling effect.
The present invention compared with the existing technology has the following advantages that and effect: the more traditional nitrous of the triethanolamine that the present invention is added
Sour sodium toxicity significantly reduces, and is easier to store, and triethanolamine has corrosion resistance, moreover it is possible to prevent crushing process powder aggregation and
Positice ground effect improves the mobility and loading density of cement, reaches preferable cement milling effect, and can reduce pulverizer
Power consumption；Each component interaction effectively prevent cement to corrode, to improve cement grinding effect.
Specific embodiment
The present invention will be further described in detail below with reference to the embodiments, following embodiment be explanation of the invention and
The invention is not limited to following embodiments.
Embodiment 1: under 16 degrees Celsius of environment, it is bright successively to take and dissolve 34.5kg water, 7.5kg Nacl, 6.5kg member
