Description
Technical field
The present invention relates to the thixotropic agent technical field, particularly relate to a kind of THIXCIN intercalation polynite thixotropic agent and preparation method thereof.
Background technology
Polyurethane sealant is because characteristic such as its adhesiveproperties is strong, mechanics superior and acid and alkali-resistance, organic solvent-resistant are good is widely used in fields such as automobile assembling, building sealing.
Yet, when one-component polyurethane sealant is applied to the facade filleting of buildings, because own wt causes the anti-sag performance poor.Therefore, in order to improve the anti-sag performance of one-component polyurethane sealant, need in one-component polyurethane sealant, to add thixotropic agent.
Thixotropic agent is called anti-sagging agent again, is a kind of auxiliary agent that can make colloid produce " thixotroping phenomenon ".When the time spent of doing that colloid receives shearing force, denseness descends, and shearing force is big more, and the denseness decline scope is also big more; Remove back (when being interrupted as stirring or shearing) when shearing force, denseness slowly returns to not runny originally state again.The effect of thixotropic agent is to prevent that colloid from trickling on inclined-plane of constructing or vertical surface, avoids colloidal content that the uneven phenomenon of levels is arranged, thereby guarantees the quality of product; And have than low-viscosity under the high shear rate when construction, help colloid to flow and be easy to construct; Have than high viscosity under the low shear rate after before construction, reaching, can prevent pigment sedimentation and wet film sagging.
In the prior art, thixotropic agent commonly used in one-component polyurethane sealant mainly includes aerosil, organobentonite, hydrogenated castor wet goods.Aerosil, because specific surface area is high, tap density is light, thus need special devices to disperse, and because its particle surface is prone to suction, be difficult in mono-component polyurethane, use.Organic expander profit soil, though have good anti-sag performance, add a certain amount of organobentonite after, be prone to cause the increase of sealer modulus, be difficult to polyurethane sealant is prepared into the product of low modulus, make it not used widely thus.THIXCIN, though have good anti-sag performance, because its molecular structure is a polyhydroxy substance; When it is applied to one-component polyurethane sealant, is prone to form gel, thereby influences the outward appearance and the memory property of product; Under hot conditions, its thixotropic property obviously reduces simultaneously.
Therefore, to deficiency of the prior art, need badly:
(1) a kind of good environmental adaptability is provided, can under different temperature, all has good anti-sag performance, and with the consistency of polyurethane sealant better, be prone to disperse, make the sealer modulus less THIXCIN intercalation polynite thixotropic agent that raises.
(2) a kind of preparation method of THIXCIN intercalation polynite thixotropic agent is provided; It is strong to adopt this preparation method to prepare environmental compatibility; Can under differing temps, have good anti-sag performance; And disperse the THIXCIN intercalation polynite thixotropic agent that the rising of sealer modulus is less with the consistency of polyurethane sealant is better, easy.
