Description
Technical field
The present invention relates to chemical fields, more particularly, to a kind of epoxy acrylate tree for improving UV priming paint grinability
Rouge and preparation method thereof.
Background technique
The dosage of general UV paint primer accounts for 70% or so, and the dosage of resin accounts for 40%-50% in UV priming paint, wherein using
It is most be exactly the high epoxy acrylate of cost performance；And the UV priming paint grinability made of traditional epoxy acrylate is imitated
Fruit is bad.
Summary of the invention
In view of the deficiencies of the prior art, the present invention provides a kind of Epocryls for improving UV priming paint grinability.
Technical solution provided by the invention is as follows:
A kind of Epocryl improving UV priming paint grinability, which is characterized in that the group comprising following weight percent
Point:
128 epoxy resin: 52-58%；
Acrylic acid: 20-25%；
Polymerization inhibitor: 0.07-0.20%；
Catalyst: 0.3-0.8%；
Lose lustre agent: 0.05-0.1%；

Monomer: 15-25%.
Further, the polymerization inhibitor is p-hydroxyanisole.
Further, the catalyst is benzyltriethylammoinium chloride.
Further, the agent of losing lustre is hypophosphorous acid.
Further, the monomer is TPGDA.
A kind of preparation method for the Epocryl improving UV priming paint grinability, comprising the following steps:
Step 1: 128 epoxy resin, acrylic acid, polymerization inhibitor, catalyst and agent of losing lustre are stirred to mixing according to the proportion
It is even；
Step 2: being to slowly warm up to 75 DEG C, stop heating, warms naturally to 90 DEG C and keep the temperature 0.5 hour；
Step 3: continuing to be warming up to 95 DEG C of heat preservations 1.5 hours certainly；
Step 4: continue to survey acid value from after being warming up to 100 DEG C of heat preservations 1 hour, when acid value is in 30-40 ㎎ KOH/g, from
It is so warming up to 115 ~ 118 DEG C and keeps the temperature 1.0 hours；
Step 5: the acid value of sampling and measuring mixture, as acid value≤5 ㎎ KOH/g, by benzyltriethylammoinium chloride, monomer, resistance
Poly- agent is added, and reduces the temperature to 80 DEG C after mixing evenly, adjusts viscosity with monomer, can obtain Epocryl.
Further, in step 5, as 5 ㎎ KOH/g of acid value >, extend 1.5 hours, then by benzyltriethylammoinium chloride,
Monomer, polymerization inhibitor are added, and reduce the temperature to 80 DEG C after mixing evenly, adjust viscosity with monomer, can obtain epoxy acrylate tree
Rouge.
Compared with prior art, the present invention has the advantage that
Powder can be acted in paint using benzyltriethylammoinium chloride, so that powder can not only be dispersed therein well,
And the surface texture of paint film is made to change, surface of the paint film intensity becomes smaller, consequently facilitating polishing.Polymerization inhibitor is added in step 2
Stability is provided for the resin after synthesis, resin is enable to be not easy to polymerize in a long time.Therefore workpiece subtracts in coating process
The replacement of few sand paper saves the time for the next process of coating to improve production efficiency, while also reducing production
Cost.
Epocryl performance prepared by the present invention is good, smell is low, is extremely applicable to UV priming paint, can improve its dozen
Mill property.The individual demand that can open up and meet more clients, has both saved resource in this way, in turn simplifies the construction of coating,
Reduce Furniture Manufacturing Enterprise cost.
