The workplace grounds such as place.
With living standard and the lifting of aesthetical standard, construction and the technological progress of surface aesthetics effect, colored Self-leveling
Cement Market is progressively opened, or even robs the share that account for PART EPOXY terrace, in great demand.But used by domestic relatively large project
The most specified import brands of colored self-leveling cement, only several home brands can squeeze into colored self-leveling cement market.
Trace it to its cause, main or domestic correlation technique is not mature enough, it is poor that product has high insufficient strength, color and luster sense organ and uniformity
With easy problems of crack.
Content of the invention
It is an object of the invention to provide a kind of have water consumption wide ranges, do not ftracture, good leveling property, surface effect after hardening
Really good, uniform color, intensity are high, and 1d is 40MPa, 28d up to more than 80MPa, excellent in abrasion resistance, durable in use the features such as water
Property epoxy self-leveling cement, with solve the problems, such as in above-mentioned background technology propose.
For achieving the above object, the present invention provides following technical scheme：
A kind of high-strength water-base epoxy colour self-leveling cement, including liquid portion and powder section,
The raw material of powder section group by weight is divided into：White portland cement 21-24 parts, white high belite
Sulfur aluminum cement 15.6-17.6 parts, white quartz sand 58-61 parts, powder body water reducer 0.10-0.12 parts, powder body defoamer 0.17-
0.20 part, aluminium-magnesium silicate 0.09-0.11 parts, tartaric acid 0.05-0.07 parts；
The liquid portion is made up of A groups and B groups：A groups add the reactive diluent of its mass fraction 10% for epoxy resin；
B groups add appropriate mill base for aqueous epoxy curing agent.
Preferably, the raw material of powder section group by weight is divided into：22.5 parts of white portland cement, white are high
16.6 parts of belite sulfur aluminum cement, white 59.5 parts of quartz sand, 0.11 part of powder body water reducer, 0.19 part of powder body defoamer, silicic acid
0.1 part of magnalium, 0.06 part of tartaric acid.
As further scheme of the invention：The mixed proportion of the powder section, liquid portion and water is powder section：
A groups：B groups：Water=100：3.5：3.5：(12-14).
As further scheme of the invention：Aqueous epoxy curing agent in liquid portion B groups is self-control modified amine solidification
Agent, main method of modifying is：Based on TEPA so as to primary amine and epoxy resin and other bis-epoxy functional group materials
Mixture reaction, then anhydride is connected, then block, pH value is adjusted to 8-9.
As further scheme of the invention：The granular size of the white quartz sand is 80-120 mesh.
As further scheme of the invention：The water-base epoxy self-leveling cement is using front preparation method：First will
The A groups and B groups of liquid portion stirs by being mixed in proportion, and adds appropriate mixing water and powder section.
As further scheme of the invention：The mixing time of the A groups and B groups of the liquid portion is 1.5-2 minutes.
As further scheme of the invention：The time that the liquid portion, powder section and water are mixed is 1.5-2
Minute, it is stirred using handheld stirring machine or planetary mortar mixer.
Compared with prior art, the invention has the beneficial effects as follows：
(1) using white high belite sulfur aluminum cement, do not ftracture after rationally compounding：It is commonly made to colored self-leveling cement all
It is that white cement is to eliminate the color mineral C4AF in grog and obtain as major gelled material with white cement, due to its C3S,
C3A contents are high, easily ftracture in the larger Self-leveling series of water consumption；Present invention uses a kind of white high belite sulfur aluminum
Cement, this cement are that C2S contents are higher, and a kind of new cement for also constituting containing sulfur aluminum cement and Gypsum Fibrosum, with volume
Good stability, microdilatancy, the features such as hydration reaction is very fast, during compound use reasonable with white cement, can make up which and shrink especially
It is the chemical shrinkage for making up early stage so as to do not ftracture；
(2) using homemade high-performance water-based epoxy component, intensity, uniformity are improved：Aqueous epoxy curing agent oil emulsion
Property epoxy resin so as to can be compatible with water, so as to play in self-leveling cement improve intensity, density, cementitiousness, carry
High viscosity, makes component uniformity more preferably, produces certain flexibility, cracking resistance；The present invention is using a kind of synthesis certainly suitable for certainly
The aqueous epoxy curing agent of levelling cement, makes self-leveling cement intensity higher, and optimum adding quantity of pulverized is the 7% or so of powder quality, makes
Obtain 1d of the present invention and reach 40MPa, 28d is up to more than 80MPa；
(3) additive such as preferred aluminium-magnesium silicate, the more excellent effect of rationally compounding acquisition：Aluminium-magnesium silicate is that a kind of thixotroping suspends
Agent, can improve the viscosity of cement slurry, make slurry evenly, surface more smooth after solidification, and make with water-base epoxy collective effect
Self-leveling cement is insensitive to water, and the slightly many also not bleedings of water, intensity also do not reduce；The height for being more suitable for self-leveling cement is used
Performance polycarboxylate water-reducer, water-reducing rate further improve self-leveling cement mobility and intensity up to more than 30%；Use more
Suitable for eliminating the defoamer of organic emulsion bubble cement, the degree of compaction and intensity of self-leveling cement can be improved, reduce surface
The defects such as pin hole, improve surface effect.
