Description
Technical field
The present invention relates to a kind of waterborne flame retardant emulsion.
Background technology
At present, the application field of environment-friendly water-based fire proofing is constantly expanded, and market prospects are bright.In the market is most of aqueous
Add fire retardant such as tetrabromobisphenol A in coating, TDE, deca-BDE etc., its flame retardant effect is to emulsion and fire-retardant
The compatibility of agent, dispersiveness have very big requirement, and water-fast, alkaline-resisting, weatherability is all poor, significantly limit the wide of them
General application.
Till now early in the twentieth century, the whole world starts numerous studies waterborne flame retardant emulsion, and many industrial circles need application
Waterborne flame retardant emulsion.Country's flame-retardant emulsion molecular weight is small at present, and crosslinking degree is not high, and market demands are not reached far.
The content of the invention
It is an object of the invention to provide a kind of waterborne flame retardant emulsion.
Waterborne flame retardant emulsion provided by the present invention includes component A and B component, and the weight ratio of component A and B component is 3-
10:1；
The component A is obtained by following steps：
（1）By 35-55 parts of methyl methacrylate, 50-100 parts of butyl acrylate, 100-170 parts of deionized water, 3-4 parts of surface
Activating agent and 10-20 parts of DAAM are well mixed, and base fluid is obtained；
（2）By 150-200 parts of deionized water, 3-4 parts of surfactant, 180-200 parts of brominated styrene, 30-80 parts of acrylic acid
Butyl ester, 70-90 part methyl methacrylate and 5-10 parts of methyl acrylate are well mixed, and obtain pre-emulsion；
（3）5-10 parts of potassium peroxydisulfate is dissolved in 50-100 parts of deionized water, initiator solution is made into；
（4）Under conditions of 80-90 DEG C of temperature, base fluid, initiator solution and pre-emulsion are mixed is reacted system, is controlled
Reaction temperature processed is at 80-100 DEG C until reaction terminates；Or, under conditions of 80-90 DEG C of temperature, first by pre-emulsion total amount
10% pre-emulsion is added in base fluid, and initiator solution is then added dropwise, and when the temperature of system begins to ramp up, then residue is added dropwise
Pre-emulsion, controlling reaction temperature continues to be protected at 80-100 DEG C at 80-100 DEG C, after completion of dropping during dropwise addition
Temperature reaction is until reaction terminates；Reaction is cooled to less than 50 DEG C after terminating, and the pH value that regulation system is adjusted with alkali is 7-8, then
1-3 parts of wetting agent and 1-2 parts of defoamer are added, component A is obtained final product after being well mixed；
The B component is the adipic dihydrazide aqueous solution.
The waterborne flame retardant emulsion also includes component C, and the weight ratio of component A, B component and component C is 300-1000:
100:2-5。
The component C is thickener.
The concentration of the adipic dihydrazide aqueous solution is 5-9%.
The step（4）In, the time for adding of remaining pre-emulsion is 1-4 hours, and initiator solution will be remaining
Pre-emulsion is all dripped off when being added drop-wise to 10-30 minutes..
The alkali is ammoniacal liquor, sodium carbonate, potassium carbonate, sodium acid carbonate or saleratus.
The present invention is raw materials used to be commercially available prod, and the surfactant is alkylsulfonate, for example, can use Shandong
The neopelex of Jinan Li Chao Chemical Co., Ltd.s production；The wetting agent is water-soluble nonionic surface-active
Agent, for example can be using the wetting agent of the entitled X-450 of Dow Chemical's production；The defoamer is polyethers defoamer,
For example can be using the defoamer of the entitled DF-104 of Dow Chemical's production；The thickener is the poly- ammonia of city's hydrophobically modified
Ester, for example can be using the thickener of the entitled RM-8W of Dow Chemical's production.
Component A of the invention and B component need to be stored individually；When using, by component A: the weight proportion of B component=3-10: 1
Relation, component A and B component is well mixed and forms mixed liquor.The present invention may also include component C i.e. thickener, to increase
Plus viscosity, can be stirred for uniform according to requirements to appropriate component C is added in the mixed liquor of component A and B component；One
As under situation, the weight proportion relation of component A B component and component C is 300-1000:100:2-5.
Step of the present invention（4）In, the foundation of reaction system can take following two modes：One can be by base fluid, draw
Hair agent solution and pre-emulsion are mixed to form reaction system；Two can be first to mix a small amount of pre-emulsion and base fluid, then drip
Plus initiator solution, remaining pre-emulsion is added dropwise again when system temperature begins to ramp up.Preferably with the second way, so more
Beneficial to facilitating controlling reaction temperature.No matter above-mentioned that mode, general control 4-8 hours reaction time of system can make reaction
Fully.Initiator solution requires that the concrete meaning dripped off in 10-30 minutes that remaining pre-emulsion starts dropwise addition is：Trigger
Agent solution first starts that a period of time is added dropwise, and then remaining pre-emulsion starts to be added dropwise, and now initiator solution is also simultaneously in drop
Plus, initiator solution will in remaining pre-emulsion is added drop-wise to the time period of 10-30 minutes whole completion of dropping.
The present invention uses various function monomers, core shell structure molecule side chain IPN is carried out to emulsion particle, by the work that is polymerized
Skill reaches the purpose of invention.Gained paint film is i.e. cross-linking under normal temperature state, has very strong adhesive force, therefore coating to base material
Mechanical performance is greatly improved, and up to 3000 times, water resistance reaches 240h to paint film scrubbing resistance number of times after tested.
