Description
Technical field
The present invention relates to the parting agent technical field, particularly a kind of water-based parting agent and preparation method thereof.
Background technology
Parting agent is one deck barrier film that applies between goods and mould in the mould adhesion for the composite product that prevents moulding, so that goods are easy to deviate from from mould, guarantees that products surface quality and mould are excellent.All might spray one deck parting agent as protective membrane, in case product surface is by scratch at digital product, household appliances, aluminium section bar, glass, surface of stainless steel product.Solution-type parting agent commonly used is non-water-soluble parting agent, and employing organic solution is solvent.The organic solution volatility is low, and residual quantity is big when dry, can not reach the inspecting standard of country.Therefore, the research and development of the water-based parting agent of environmental protection have obtained people's more concern.
Summary of the invention
The object of the invention is to provide a kind of water-based parting agent and preparation method thereof, this water-based parting agent is solvent with the deionized water, environmental protection, pollution-free, good leveling property, stretchiness is good, film forming is even, and rate of drying is fast, external crosslinking can not take place during use, peel off easily after the film forming, can enhance productivity.
Technical solution proposed by the invention is such:
A kind of water-based parting agent, the consumption that the recipe ingredient of this water-based parting agent calculates with mass parts is:
Modified aqueous acrylic acid resin 25-35 part;
Deionized water 50-70 part;
Linking agent 1-4 part;
Defoamer 0.1-0.5 part;
Ethylene glycol 1-5 part;
Improvement based polyurethane 0.1-0.5 part;
Mass concentration is ammoniacal liquor 0.1-0.6 part of 15%;
Wherein: the modified aqueous acrylic acid resin is respectively with the ratio of the mass parts of linking agent:
The described linking agent of filling a prescription is polycarbodiimide or trifunctional aziridine.
The described defoamer of filling a prescription is modified organic silicon or polyether silicone oil.
Go to prepare the method for water-based parting agent according to the prescription of above-mentioned water-based parting agent, its preparation process is as follows:
(1) be that the modified aqueous acrylic acid resin of 25-35 part and deionized water that mass parts is 50-70 part are rendered in the reactor with mass parts, stirring at low speed under 20-30 ℃ temperature, doing with high speed dispersor, its rotating speed is 300-400 rev/min, stir after 3-6 minute, obtain finely dispersed emulsion;
(2) to add mass parts be that the linking agent of 1-4 part, defoamer and the mass parts that mass parts is 0.1-0.5 part are the ethylene glycol of 1-5 part to the emulsion in the reactor; Wherein, the ratio of the mass parts of the modified aqueous acrylic acid resin of the linking agent of adding and step (1) adding is chosen by following five class ranges: 1.0-1.6:25-27; 1.6-2.2:27-29; 2.2-2.8:29-31; 2.8-3.4:31-33; 3.4-4.0:33-35; At this moment, the rotating speed of high speed dispersor is brought up to 2500-3500 rev/min, adding mass parts in this rotating speed stirs the downhill reaction still is the improvement based polyurethane of 0.1-0.5 part, stirs then 20-30 minute, obtains coating; Described linking agent adopts polycarbodiimide or trifunctional aziridine; Described defoamer adopts modified organic silicon or polyether silicone oil;
(3) will splash in remaining coating on the reactor inwall and scrape in the coating in the still, stir then 5-10 minute;
(4) measure the pH value of reactor inner-wall paint with accurate pH test paper, then with mass parts be the mass concentration of 0.1-0.6 part be 15% ammoniacal liquor regulate this coating the pH value to 6.2-8.2, namely obtain the water-based parting agent.
Compared with prior art, the present invention has following unusual effect:
Gordian technique part of the present invention be to select modified aqueous acrylic acid resin and linking agent carry out fully, crosslinked in completely, the specific energy of the mass parts of the modified aqueous acrylic acid resin of crosslinking reaction and linking agent satisfies its complete internally crosslinked requirement in needing to participate in.For this reason, listed five groups of mass parts proportional ranges in claimed technical scheme, in these scopes, this water-based parting agent just can obtain interior crosslinked completely in preparation process between modified aqueous acrylic acid resin and the linking agent.After, external crosslinking can not take place with it, thereby peel off easily after making water-based parting agent film forming when using these water-based parting agent spraying protected objects.When if the linking agent addition is not enough or excessive (corresponding to described five groups of mass parts proportional ranges), the water-based parting agent for preparing meeting and protected object generation external crosslinking after the spraying film forming, thus cause protective membrane to be difficult to peel off.
Linking agent can adopt trifunctional aziridine or polycarbodiimide, makes the linking agent best results with polycarbodiimide.Defoamer can adopt polyether silicone oil or modified organic silicon, makes defoamer effect the best with modified organic silicon.The modified aqueous acrylic acid resin can make the consistency of itself and deionized water better, can shorten the time of drying after the parting agent film forming.Select modified organic silicon to be that as defoamer it and deionized water consistency are good, the defoaming effectiveness height.Improvement based polyurethane as thickening material can be issued to extraordinary thickening effectiveness in the situation of few additive.Ethylene glycol as antifreezing agent can make the water-based parting agent, can thaw half an hour in the room temperature placement after freezing one hour-10 ℃ temperature.Owing to selected above-mentioned materials, taked abovementioned technology, so this water-based parting agent good leveling property, stretchiness is good, film forming is even, and rate of drying is fast, peels off easily after the film forming, improved production efficiency widely, simultaneously owing to be to be solvent with the deionized water, not with an organic solvent, so environmental protection, pollution-free, cost is low.
