Abstract
The invention relates to a composite cement grinding aid, and belongs to the technical field of cement grinding aids. The composite cement grinding aid comprises the following raw materials by weight: 20-30 parts of polyethylene glycol ether, 15-25 parts of a sulfonated melamine resin, 10-20 parts of diatomaceous earth, 10-20 parts of hydroxypropyl methyl cellulose, 5-10 parts of triisopropanolamine, 5-10 parts of methacrylic acid, 1-5 parts of beta-hydroxyethyl ethylenediamine, and 1-5 parts of sodium lignin sulfonate. According to the composite cement grinding aid of the present invention, through the reasonable ratio of various raw materials, under the premise of the small doping amount, the yield per unit of time is increased to more than or equal to 15%, the 3-day cement strength can be increased to more than or equal to 3 MPa, and the 28-day cement strength can be increased to more than or equal to 5 MPa.
Description
Technical field
The invention belongs to cement grinding aid technical field, be specifically related to composite cement grinding aid.
Background technology
Cement grinding aid is a kind of chemical additive improving cement grinding effect and performance, can significantly improve cement unit-hour output, each length of time strength of cement, improve its mobility.Cement grinding aid significantly can reduce the electrostatic adhesion bag ball phenomenon formed in grinding process, and can reduce the again coalescent trend of the ultra-fine grain formed in grinding process.Cement grinding aid also significantly can improve cement fluidity, improves the grinding effect of grinding machine and the grinding efficiency of powder separating machine, thus reduces grinding energy.The cement using grinding aid to produce has the coalescent trend of lower compacting, thus is conducive to the handling of cement, and can reduce the wall cling phenomenon of cement silo.
But it is not high that product efficiency is put forward in cement grinding aid existence of the prior art, puies forward the defects such as strong DeGrain to the cement of large dosage Wingdale.
Summary of the invention
For prior art Problems existing, the object of the invention is to design the technical scheme that a kind of composite cement grinding aid is provided.
Described composite cement grinding aid, is characterized in that being made up of the raw material of following weight part: polyglycol ether 20-30 part, sulfonated melamine resin 15-25 part, diatomite 10-20 part, Vltra tears 10-20 part, tri-isopropanolamine 5-10 part, methacrylic acid 5-10 part, beta-hydroxyethyl quadrol 1-5 part, sodium lignosulfonate 1-5 part.
