Abstract
The invention relates to a cement modifier, which is characterized by comprising the following components according to a proportion: 80-85kg of vinyl acetate-ethylene copolymer emulsion, 2-2.5 kg of methyl alcohol, 1.0-1.4 kg of polyvinyl alcohol, 0.001-0.005kg of surface active agent JFC, 0.001-0.005kg of n-octyl alcohol and 25-30kg of water. The cement modifier disclosed by the invention is simple in preparation process and low in cost, and can effectively improve the quality of cement so as to improve the quality of buildings.
Description
Technical field
The present invention relates to a kind of material of construction, specifically a kind of cement modifier.
Background technology
Cement is important material of construction, and the quality of cement directly affects the quality of buildings.The Portland cement that uses at present easily hardens, even be full of cracks occurs, causes tensile strength low, poor toughness, and warming effect is poor, therefore, cement is carried out modification, and it is very important improving cement quality.
Summary of the invention
Purpose of the present invention provides a kind of cement modifier, can the Effective Raise cement quality.
For achieving the above object, the technical scheme that adopts is:
A kind of cement modifier is characterized in that being mixed with by vinyl acetate-ethylene copolymerization emulsions, methyl alcohol, polyvinyl alcohol, tensio-active agent JFC, defoamer n-Octanol and water.Its ratio of components is:
Vinyl acetate-ethylene copolymerization emulsions 80-85kg, methyl alcohol 2-2.5 kg, polyvinyl alcohol 1.0-1.4kg, tensio-active agent JFC 0.005-0.001kg, n-Octanol 0.005-0.001kg and water 25-30kg.
A kind of preparation method of cement modifier is that 25-30kg water is joined in the reactor, be heated to 80-95 ℃ of temperature after, in reactor, add the 1.0-1.4kg polyvinyl alcohol, under agitation, be heated to 90-95 ℃, polyvinyl alcohol is all dissolved, be cooled to 50-55 ℃, in reactor, add 2-2.5kg methyl alcohol, tensio-active agent JFC 0.005-0.001kg again, stir 10-20min, add at last vinyl acetate-ethylene copolymerization emulsions 80-85kg, stir 30-60 min, and get final product.
Advantage of the present invention
Cement modifier of the present invention, manufacturing process is simple, and cost is low, energy Effective Raise cement quality, thus improve structural quality.
