Abstract
The invention discloses a curing agent suitable for a water-in-oil epoxy resin emulsion system. The curing agent is polymerized of dimer acid, aliphatic acid and polyethylene polyamine, wherein the HLB (Hydrophile-Lipophile Balance) value is between 7 and 10; the weight-average molecular weight is from 1500 to 2600. The curing agent and the liquid epoxy resin emulsion system can form a stable water-in-oil emulsion in the presence of an emulsifying agent. In addition, the obtained water-in-oil emulsion can be stably stored for more than 30 days. The water-in-oil epoxy resin-curing agent system has a good effect when used for the manufacturing of a microporous ceramic molding die.
Description
Technical field
This invention belongs to the ceramic mould polymeric material field, relates to solidifying agent of micropore ceramics forming mould and preparation method thereof, relates in particular to solidifying agent that is applicable to epoxy resin-matrix micropore ceramics forming mould and preparation method thereof.
Background technology
Traditional ceramic mould material is gypsum, the micropore polymeric mold is the ideal substitute of gypsum mold, and we have reported a kind of manufacture method of the epoxy resin-matrix Microcellar plastic mold for forming process of ceramics in Chinese invention patent ZL200610146610.8.The method is take Resins, epoxy as main raw material, is aided with inorganic strengthening agent, and by forming water-in-oil emulsion, then moulding is coated on the moisture evaporation pore in the Resins, epoxy with the solidifying agent reaction, forms Microcellar plastic mold.
Because this kind mould at first was to form stable water-in-oil emulsion in moulding in the past, the solidifying agent that therefore adopts must have certain wetting ability, helps simultaneously the stable of water-in-oil epoxy resin latex.Most of fatty amines solidifying agent all are water miscible, and Resins, epoxy then is hydrophobic type, so aliphatic amide can't solidified liquid Resins, epoxy in water.Therefore need change the molecular structure of aliphatic amide by introducing hydrophobic group, increase its in water with the consistency of Resins, epoxy, improve simultaneously the ability of its emulsion epoxy resin.
Aqueous epoxy curing agent mainly contains 3 classes: the amidated polyamines that 1) is made by polyamine and mono fatty acid reaction; 2) carry out the polymeric amide that condensation forms by dimeracid and polyamine; 3) polyamines-epoxy adduct that is obtained by polyamine and Resins, epoxy addition.Modal be the third part acid neutralized reaction product (as, Zhou Jiliang etc., 2005,33(2): 25-28), but these waterborne curing agents all were that traditional oil-in-water-type Resins, epoxy is had stabilization in the effect of performance solidifying agent in the past, and were not suitable for curing and the stabilization of water-in-oil-type Resins, epoxy.Be embodied in the hydrophile-lipophile balance value (HLB value) that is applicable in other words the solidifying agent of this water-in-oil system on the quantizating index than little many of traditional waterborne curing agent.The HLB value of general Resins, epoxy is about 3, and the HLB value of the third waterborne curing agent is much higher, can't match.
Therefore, the solidifying agent that requirement is suitable for this invention should have certain wetting ability, and its lipophilicity must be higher than traditional waterborne curing agent simultaneously, considers to have water in oil emulsifying effect concurrently, this lipophilicity requires again can not be too high, and a suitable coupling must be arranged.
Summary of the invention
One of purpose of the present invention is synthetic a kind of synthesized solidified dose of being applicable to water-in-oil epoxy resin latex system and preparation method thereof, and it should have water in oil emulsifying effect concurrently, and the HLB value is between 7-10, and weight-average molecular weight is 1500-2600.And its with should have certain working life after epoxy-resin systems mixes, namely stability requires to have at normal temperatures the stable storing phase more than 30 days.
A kind of synthesized solidified dose of being applicable to water-in-oil epoxy resin latex system, dimeracid and lipid acid and polyethylene polyamine polymerization obtain, and the HLB value is between 7-10, and weight-average molecular weight is 1500-2600.
Described dimeracid refers to dimer (fatty acid) yl, is selected from a kind of in linolic acid dimeracid, eleostearic acid dimeracid, the synourin oil dimeracid, preferably the linolic acid dimeracid.
Described lipid acid is selected from oleic acid, Palmiticacid, stearic acid, preferably oleic acid.

The molar mass proportioning of dimeracid and lipid acid be 6:4 to 9:1, total carboxyl mol ratio is 0.9～1.1:1 with the amino mole proportioning of the end of polyethylene polyamine in dimeracid and the lipid acid.
Synthesized solidified dose the synthetic method that this is applicable to water-in-oil epoxy resin latex system comprises the following steps:
1) dimeracid and lipid acid are joined in the reaction flask, stir and be warming up to 180-220 ℃, insulation is lower, drips polyethylene polyamine in 3 hours, constantly tells the water of generation simultaneously, after dripping, and restir reaction 1 hour.
2) cool to 40 ℃ after, stir down, in 1 hour, drip the organic acid that is equivalent to polyethylene polyamine 30%-40% mole proportioning.
Preferably, in the step 1) molar mass proportioning of dimeracid and lipid acid be 6:4 to 9:1, total carboxyl mol ratio is 1:1 with the amino mole proportioning of the end of polyethylene polyamine in dimeracid and the lipid acid.
Preferred, the molar mass proportioning of dimeracid and lipid acid is that 7:3 is to 8:2 in the step 1).
Temperature of reaction when preferably, being incubated in the step 1) is 200-210 ℃.
The synthesized solidified dose of molecular weight of most importantly controlling product by the adding of oleic acid of this invention, the ratio of control dimeracid/oleic acid and polyethylene polyamine is controlled its HLB value.It has the function of solidifying agent and emulsifying agent concurrently, can be adsorbed on to help to form stable water-in-oil emulsion on the interface of water and Resins, epoxy, and can stably stored more than 30 days.At above water-in-oil Resins, epoxy-curative systems during for the manufacture of the micropore ceramics forming mould, by adding a certain proportion of T31 and polyamide 6 50 solidifying agent, initial solidification reaction heat is being provided more than 50 ℃, impel above system breakdown of emulsion, cause the hot setting reaction of aforementioned solidifying agent and Resins, epoxy, and make the moisture evaporation pore.
