Description
Technical field
The invention belongs to technical field of adhesive, relate to a kind of tackiness agent of the environment-friendly type high intensity for the building crack and preparation method thereof, be mainly used in the maintenance in building crack.
Background technology
In the last few years, along with the development of China's building building cause, people were more and more higher to the construction quality requirement of building, still, because of the impact of the undesirable elements such as construction, to the later stage, used and hid some dangers for, and the phenomenons such as width crack occurred, and impact is normally used.But traditional repairing is all to use the solvent borne caking agent to carry out cementation of fissures repairing, solvent discharge serious environment pollution, harm health of human body.Healthy for the people, for stopping to pollute, in line with guaranteeing safety, take into account the principle of economic environmental protection, adopt aqueous epoxy emulsion and the materials such as waterborne curing agent and superfine cement, we have developed a kind of tackiness agent of the environment-friendly type high intensity for the building crack, and this environment-friendly type high intensity tackiness agent carries out cementation of fissures processing, repairing, reinforcing to the building crack, not only environmental protection but also safe and reliable.Facts have proved that this environment-friendly type high intensity tackiness agent is a kind of novel material that cementation of fissures processing is carried out in the building crack, the environment-friendly type high intensity tackiness agent has no bibliographical information so far.
Summary of the invention
A kind of tackiness agent of the environment-friendly type for the building crack of the present invention, each component and quality percentage composition respectively: aqueous epoxy emulsion 69-73%, triallylamine waterborne curing agent 19-25%, superfine cement (DMFC-GM) 2-6%,
phthalic acid two monooctyl ester (DOP)0.15-0.2%, KS25 sterilant 0.1-0.2%, tap water 2.6-5.73%.
The preparation method of a kind of tackiness agent of the environment-friendly type for the building crack of the present invention, the steps include:
1. first aqueous epoxy emulsion and dioctyl phthalate (DOP) (DOP) are placed in container, with GST-20LB type Handheld mixer, power of motor is 0.1Kw, and rotating speed 1200r/min stirs 19-23min even.
2. superfine cement (DMFC-GM) is put into to bucket, then tap water is all added in bucket, after stirring 14-18min is even; After adjusting rare grout to join in above-mentioned steps 1 container in bucket to stir 19-23min evenly, then add the KS25 sterilant, stir 14-18min even.
3. and then by the triallylamine waterborne curing agent add, stir the even slaking of 19-23min and can use.Within two hours, be finished matching while using.
Environment-friendly type for building crack tackiness agent content of volatile organic compound of the present invention is low, containing formaldehyde, not nontoxic, environmental protection, bonding strength, ultimate compression strength, tensile strength, cohesive force are all strong, surface drying time is fast, and cost is low, and technique is simple, the advantages such as easy construction, over-all properties is significantly increased, and is a kind of New-type building crack environment-friendly type high intensity tackiness agent, is the ideal substitute of the common crack of traditional building tackiness agent.The major cause that effect produces: the novel process that adopts the material such as aqueous epoxy emulsion and waterborne curing agent and superfine cement and environmental protection auxiliary agent to become reconciled makes the performance of product nontoxic, environmental protection; Solved traditional use solvent borne caking agent and carried out the problem that the cementation of fissures is repaired serious environment pollution, stopped pollution, guaranteed that the people's is healthy.Superfine cement (DMFC-GM) material specific surface area is large simultaneously, and particle diameter is little, and slurry fluidity is good, and concrete castability is high, and after the auxiliary agents such as superfine cement and aqueous epoxy emulsion and waterborne curing agent solidify, cohesive strength is high, and good endurance is not aging, and anti-permeability performance is good.The over-all propertieies such as bonding strength, ultimate compression strength, tensile strength significantly improve.
