Abstract
The invention discloses a kind of floor coatings that can be low-temperature fast-curing, it is made of component A and B component, wherein component A is by pre-mixed resin 30~50%, the quartz sand 20~45% of 100~200 mesh, the silica flour 20~35% of 600~800 mesh, defoaming agent 0.5~1%, levelling agent 1~3% form, B component is initiator benzoyl peroxide, and dosage is the 2~4% of component A.- 30 DEG C~-20 DEG C of floor coating construction temperature of the present invention, after construction in 1~3 hour can rapid curing, be suitble to the construction usage in cold winter and freezer, be particularly suitable for freezer use when ground is repaired online, do not influence the normal use of freezer.
Description
Technical field
The invention belongs to technical field of coatings, are related to a kind of ground brushing coating, can be -30 more particularly to one kind
The floor coating of construction is rapidly completed under~-20 DEG C of low temperature environments.
Background technique
Traditional epoxy resin, polyurethane ground coating are more sensitive to temperature in solidification, and curing time is longer.When
At 0 DEG C or less, the viscosity of resin can become larger construction environment temperature in coating, can not solidify, in winter with some special fields
Conjunction is not available at all.And the weatherability of such coating is poor, can not use outdoors.
The application of existing MMA floor coating then compensates for these defects.The curing cross-linking reaction of MMA floor coating belongs to certainly
By base polymerization reaction, it is affected by temperature very little, construction can be solidified under -10~40 DEG C of temperature environment.The experiment proved that
MMA floor coating can complete construction within the scope of 5~40 DEG C in 1 hour；It can be small 2~3 within the scope of -10~0 DEG C
When interior completion construction.
Meanwhile there is no unsaturated bond after MMA floor coating film-forming, so having for acid, alkali, oil, salt fog and drug
Have anti-by property, and the load resistance of coating after solidify, wear-resisting, impact resistance, anti-scratch, weather-proof, the resistance to performances such as ultraviolet are also all preferable.
However, unfortunately, when construction environment temperature is within the scope of -30~-20 DEG C, such as the spies such as freezer, refrigerating chamber
Place is determined when being constructed under not stopping freezing state, and the resin system of existing MMA floor coating does not solidify tacky, Huo Zhexu
Want could solidify within 5~7 hours, and the performance after solidifying is not up to standard, paint film feels like jelly, and hardness is inadequate.
Summary of the invention
The purpose of the present invention is make up existing floor coating not applied under -30~-20 DEG C of colds and freezing environment
The deficiency of work provides the floor coating that one kind can be low-temperature fast-curing and expands coating to reduce the execution conditions of floor coating
Use scope.
It is of the present invention can low-temperature fast-curing floor coating be to be made of component A and B component, wherein it is described
Component A be grouped as by the group of following mass percentage: the quartz sand 20 of 30~50%, 100~200 mesh of pre-mixed resin~
45%, the silica flour 20~35% of 600~800 mesh, defoaming agent 0.5~1%, levelling agent 1~3%；The B component is initiator mistake
Benzoyl Oxide (BPO), dosage are the 2~4% of component A quality.
Further, the pre-mixed resin in the component A is made of the raw material mixing of following mass percentage: third
Olefin(e) acid resin 25~35%, acrylate monomer 60~70%, wax additives 1~3%, curing accelerator 0.5~2%.
In turn, one of the raw material as composition pre-mixed resin, the acrylic resin are preferably methyl methacrylate, first
The suspension polymerization product of base butyl acrylate, double pentaerythritol C5 methacrylate and styrene under free radical initiation.
More specifically, the acrylic resin is with 30~40wt% methyl methacrylate, 30~45wt% methyl-prop
Olefin(e) acid butyl ester, 20~25wt% double pentaerythritol C5 methacrylate, 4~10wt% styrene are raw material, in 0.4~4wt% initiator
In the presence of benzoyl peroxide, it is heated to 75~80 DEG C and reacts 2 hours, then be warming up to 85~90 DEG C of reactions obtained production in 2 hours
Object.
As another primary raw material of composition pre-mixed resin, the acrylate monomer can be methyl methacrylate
Ester, the just own ester of methacrylic acid, ethyl acrylate, butyl acrylate, hydroxypropyl acrylate, ethylene glycol dimethacrylate,
3,3- methyl methacrylate, 1,6-HD dimethylacrylate, polyethylene glycol dimethacrylate, pentaerythrite
Triacrylate, double pentaerythritol C5 methacrylate, trimethylolpropane trimethacrylate, trimethylol propane trimethyl propylene
One of acid esters, ethoxylated neopentylglycol diacrylate or several arbitrary proportion mixtures.
The wax additives can be one of polyamide wax, polyethylene wax, chlorinated paraffin or several timess
Meaning scalemic thereof.Anti-settling property, resistance to marring and the toughness of floor coating can be turned up in the use of wax additives, can also be every
Exhausted air is to prevent resin from aoxidizing.
The curing accelerator added in the pre-mixed resin can be N, N'- dimethyl-p-toluidine, N, N'- diisopropanol
The solidification of open-chain crown ether, N, the routine such as N'- dimethyl benzylamine, zinc Isoocatanoate, benzyl dimethylamine, vanadium phosphate, triphenylphosphine promotees
Into one of agent or a variety of.
Further, the levelling agent and defoaming agent added in floor coating component A of the present invention is that paint field is conventional
Levelling agent and defoaming agent.Preferably, the levelling agent that the present invention uses is any one in BYK-333, BYK-465, BYK-326
Kind, defoaming agent is any one in BYK-1788 or BYK-1799.
In turn, the present invention can also be added with proper amount of filler talcum powder or kaolin in the component A, to increase
The mobility and hardness of paint film of coating, and prevent coating from precipitating.
When construction environment is relatively moist, can also be added in component A attached by the BE of German Ying Chuan company production
Adhesion promoter, to improve the adhesive force of coating and ground.
The present invention can also be added with proper amount of mill base in the component A, with prepare it is being suitble to that different places use,
The floor coating of different colours.
Floor coating prepared by the present invention is more the floor treatment applied to food stuff refrigerated storage.For its environmental quality,
Fungicide and mould inhibitor can be added in right amount in coating.
Floor coating prepared by the present invention is suitble to the construction usage in cold winter and freezer, and -30 DEG C of construction temperature
~0 DEG C, after construction in 1~3 hour can rapid curing, be particularly suitable for freezer use when ground is repaired online, do not influence
The normal use of freezer.
Coating of the present invention equally has excellent weatherability, ultraviolet resistance is good, non-discolouring after -30~-20 DEG C of solidifications.
