Abstract
The invention discloses a kind of special anti-sagging agent production technology of cast paint, step is as follows：1) compound A preparation：Hexamethylene diisocyanate urea diketone is mixed with inert agents first, monoamine is then added dropwise；2) by step 1) hybrid reaction under the conditions of 60 ~ 120 DEG C of obtained product and monoamine, obtained biuret compounds are invented anti-sagging agent.The special anti-sagging agent material of cast paint prepared according to the present invention, significantly reduces the paint sagging in construction, precipitation is reduced, while further improving brushing characteristic.
Description
Technical field
The present invention relates to a kind of special anti-sagging agent production technology of cast paint, belong to high polymer material technology of preparing neck
Domain, preparation and application available for resist sagging type coating.
Background technology
The continuous improvement and the increasingly formulation of strict Law on Environmental Protection realized with human environment protection, by
Step trend uses high solid coating, to reduce the pollution that solvent volatilizees to air in construction.Coatings chemistry man is using new
The resin of exploitation, its feature is that molecular weight is relatively low, but the active function groups on molecule segment are more.It is standby with this kind of resin-made
The advantage of coating system is that good leveling property, gloss is high, paint film is plentiful, but it has the disadvantage easy sagging.
In the spraying of coating and drying course, for the coating system of middle and high solid point, it is important to note that controlling stream
Hang, while to ensure to obtain smooth, smooth paint film, the levelability for having maximum possible in work progress is required again.Coating exists
Occur sagging in construction, except in construction wet film it is blocked up and viscosity is too low cause in addition to, it is often more important that in film baking process
In, due to temperature rise, the viscosity of film has one drastically to decline, the change procedure then risen again.The painting of middle and high solid point
This phenomenon of material system becomes apparent.The degree of sagging depends on the absolute value of mobility, i.e. relative time reciprocal viscosity.If stream
Degree is more than certain value, just there is sagging appearance.
The content of the invention
In order to overcome the deficiencies in the prior art, the invention provides a kind of preparation of glass fibre reinforced nylon composite
Method, it is characterised in that comprise the following steps：

2) by step 1) hybrid reaction under the conditions of 60 ~ 120 DEG C of obtained product and monoamine, obtained biuret compounds are
The anti-sagging agent invented.
Preferably, described monoamine is aliphatic, alicyclic and aromatic aliphatic amine.
Preferably, described aliphatic is that chain length is C1~C22Straight chain, side chain or cyclic amine in one or more.
Preferably, described chain length is C1~C22Straight chain, side chain or cyclic amine for aliphatic amine can be ethamine, propylamine,
Isopropylamine, butylamine, sec-butylamine, tert-butylamine, hexylamine, octylame.
Preferably, described aromatic aliphatic amine is one or both of Bian amine and chaff amine.
Preferably, described inert agents are one kind in toluene and dimethylbenzene.
Preferably, described step 1) obtained product and monoamine reaction molar ratio 1:0.8~1:1.5.
Preferably, described step 1) molar ratio of obtained product and monoamine reaction is 1:1.
Preferably, described step 1) obtained product and monoamine hybrid reaction temperature be 80 ~ 90 DEG C.
Beneficial effect：The invention provides a kind of preparation technology of new sagging agent, victory can efficiently it prepare quickly
One class biuret compounds are used as rheological characteristic control additive, while the product prepared can be good in reduction construction
Sagging phenomenon, reduces precipitation, while further improving brushing characteristic.
Embodiment
The present invention is described in further detail below, to make those skilled in the art being capable of evidence with reference to specification word
To implement.
Embodiment 1：By hexamethylene diisocyanate urea diketone（0.5mol）Mixed with toluene, add equipped with agitator,
In the 1L three-necked flasks of reflux condenser and thermometer, tridecyl amine is then added dropwise dropwise（1.0mol）, it is heated to 70 degree of reactions
