Abstract
The invention relates to the technical field of building cement auxiliary materials, and specifically relates to a multi-effect modifier for building cement. The modifier is composed of the following components in parts by weight: 1 to 8 parts of methyl cellulose ether, 5 to 6 parts of glycol, 8 to 10 parts of glyoxal, 8 to 10 parts of polyvinyl alcohol, 3 to 5 parts of isobutene, 40 to 80 parts of vinyl acetate-ethylene copolymer emulsion, and 100 to 150 parts of water. The invention aims to provide a building cement multi-effect modifier having the advantages of low cost and prominent effect.
Description
Technical field
The present invention relates to construction cement auxiliary material technical field, specifically a kind of construction cement multiple-effect properties-correcting agent.
Background technology
Cement is important material of construction, and the quality of cement directly affects the quality of buildings.Easily there is hardening phenomenon in the cement used in current building, major cause is that calcium hydroxide, Calucium Silicate powder and water-setting are poly-.Such cement is easy to crack performance occurs, and then causes that cement tensile strength is low, toughness is low.In order to address this problem, generally all need to add properties-correcting agent in this kind of cement, hardening of cement phenomenon is improved.But also there is the defects such as water-repellancy difference, cohesive force are little, not wear-resisting, not freeze proof in some Portland cements while existence easily sclerosis.In order to these problems solving Portland cement just need to add various different properties-correcting agent, additive etc., who so causes the performance of cement to be improved like this, but considerably increases the cost of cement.Because the composition of each additive is different, also may occur that the composition in different additive reacts, and causes the phenomenon that cement cannot normally use.
Summary of the invention
The object of this invention is to provide a kind of with low cost, the construction cement multiple-effect properties-correcting agent of Be very effective.
The technical solution used in the present invention is, a kind of construction cement multiple-effect properties-correcting agent, be made up of by weight following component: methyl cellulose ether 1-8 part, ethylene glycol 5-6 part, oxalic dialdehyde 8-10 part, polyvinyl alcohol 8-10 part, iso-butylene 3-5 part, vinyl acetate-ethylene copolymerization emulsions 40-80 part, water 100-150 part.
Advantage of the present invention: with low cost, technical problems such as preferably resolving hardening of cement, water-repellancy is poor, cohesive force is little, be not wear-resisting, not freeze proof, improves its workability effectively, has short solidifying, early strong effect concurrently.
Embodiment
The present invention is further described with the following Examples.
Embodiment 1, a kind of construction cement multiple-effect properties-correcting agent, is made up of by weight following component: methyl cellulose ether 1 part, ethylene glycol 5 parts, oxalic dialdehyde 8 parts, polyvinyl alcohol 8 parts, iso-butylene 3 parts, vinyl acetate-ethylene copolymerization emulsions 40 parts, 100 parts, water.
Embodiment 2, a kind of construction cement multiple-effect properties-correcting agent, is made up of by weight following component: methyl cellulose ether 4.5 parts, ethylene glycol 5.5 parts, oxalic dialdehyde 9 parts, polyvinyl alcohol 9 parts, iso-butylene 4 parts, vinyl acetate-ethylene copolymerization emulsions 60 parts, 125 parts, water.
Embodiment 3, a kind of construction cement multiple-effect properties-correcting agent, is made up of by weight following component: methyl cellulose ether 8 parts, ethylene glycol 6 parts, oxalic dialdehyde 10 parts, polyvinyl alcohol 10 parts, iso-butylene 5 parts, vinyl acetate-ethylene copolymerization emulsions 80 parts, 150 parts, water.
Should be understood that this embodiment is only not used in for illustration of the present invention to limit the scope of the invention.In addition, should be understood that those skilled in the art can make various changes or modifications the present invention, and these equivalent form of values fall within the protection domain that the application's appended claims limits equally after having read the content that the present invention lectures.
