For cumyl peroxide or benzoyl peroxide.This is because cumyl peroxide is as friendship
Connection agent also has high intensity and resistance to ag(e)ing.Benzoyl peroxide can also improve system as crosslinking agent
The cement obtained covers the covering power of material.
Preferably, described initiator is persulfate, peroxide, redox initiator
In one or more.During it is highly preferred that the present invention uses described initiator, by described initiation
It is 5～10% initiator solution that agent water is configured to initiator weight accounting.Such as, by described
It is 5%, 7% or 10% initiator solution that initiator water is configured to initiator weight accounting.
Wherein, described persulfate is potassium peroxydisulfate or ammonium persulfate.Described peroxide is tertiary fourth
Base hydrogen peroxide or hydrogen peroxide.
As the present invention more preferably embodiment, the cement of the present invention covers material, wherein, presses
Percent by weight, including: 50% water, 25% vinyl acetate, 8%VV-10,12% isocyanide fat,
0.2% hydroxyl second fat, 0.4%GMA, 0.05%IOMP, 1%NP-40,0.3%1035,3% are handed over
Connection agent, 0.02% initiator, 0.03%MA.The cement prepared under above-mentioned optimization formula covers
It is strong that material has covering, and adhesive force is high, and hardness is high, effectively prevent general cement and covers material
Not directly cover after expecting on highway cement, support column cylinder and on old building metope
Cover other material, hide the defect such as poor-performing, be highway cement, support column cylinder and
The preferable cement of Old building renovation covers material.
Preferably, water of the present invention is deionized water.
Covering material based on above-mentioned cement, the present invention also provides for a kind of cement and covers the preparation of material
Method, wherein, including step: according to above-mentioned formula, by all of emulsifying agent and 1/3-1/4
Monomer all add head tank and emulsify, during emulsifying, head tank adds water,
The most afterwards head tank is started to warm up to 60-80 DEG C, treats that in head tank, emulsifying materials is complete,
Till backflow, add the initiator that weight ratio is 20～30%, more remaining monomer is added
React to head tank, and keep interval at regular intervals to add residue 6～the initiator of 8%
Until being finished, keeping 50-60 to turn/min at this rotating speed, adding within the 4-4.5 little time, treat
Monomer has dissolved, and is all added by remaining initiator without backflow again, then is warming up to 70-85 DEG C,
