Abstract
The invention provides a method for dispersing a thixotropic agent in a resin anchoring agent. A composite dispersing method combining thermal dispersion, chemical dispersion and mechanical dispersion is adopted. The thixotropic agent can be enabled to be fully dispersed in an unsaturated polyester resin by the method, so that the thixotropic property, the precipitation and the mechanical properties of a resin cement gum are improved. The obtained resin anchoring agent is excellent in quality and stability.
Description
Technical field
The present invention relates to the resin anchoring agent field, be specifically related to the dispersing method of thixotropic agent in a kind of resin anchoring agent.
Background technology
Resin anchoring agent is by resin-bonded mastic and solidifying agent two portions comparting packaging scroll.The paste mixture that resin-bonded mastic is made up of chemical assistants such as resin, filler, promotor and thixotropic agent, it is one of two big components of anchoring agent, also is the decisive component of fundamental propertys such as product installation capability, mechanical property and shelf characteric.In the composition of resin-bonded mastic, what thixotropic agent brought to resin-bonded mastic is not only thixotropic property, also has antisolvent precipitation performance and mechanical property.The effect of thixotropic agent is the thixotropy index that increases resin, helps conveying and the stirring in the use in the anchoring agent production process; Simultaneously can prevent solid materials and the resin layering in the clay.It is to guarantee that it obtains suitable dispersion in resin that aerosil will reach the thixotroping effect key that needs as thixotropic agent.Disperse design good more, then validity is good more.The more quality problems of resin anchoring agent appearance are resin-bonded mastic layering and precipitatings and seal seepage resin (being commonly called as layering and gummosis) in the industry, and the reason of quality defects has a lot of aspects.Wherein the most directly reason is exactly the thixotroping effect that the used thixotropic agent of production anchoring agent does not reach to be needed.The employed thixotropic agent of a lot of anchoring agent manufacturers is an aerosil, and aerosil (being commonly called as thermal silica) is a kind of meticulous, special amorphous powder body material, specific surface area 50～380m
2/ g, average primary particle diameter is about the 7-40 nanometer, uses conventional mechanical dispersion mode to be difficult to guarantee aerosil nano-powder dispersive validity; More can't suppress the secondary self aggregation phenomenon of dispersive nanoparticle.Because the characteristics of resin anchoring agent industry; Have considerable medium-sized and small enterprises dispersing apparatus very backward, the basic shearing force that formed not is a kind of stirring during dispersion; Aerosil is basic in resin to have formed not reticulated structure, thereby can't bring into play the performance of material.Cause the many manufacturers of major cause of this situation not recognize dispersive importance, thereby cause resin-bonded mastic phenomenons such as layering, gummosis to occur, caused the financial loss of anchoring agent manufacturer, directly influence supporting safety.
Summary of the invention
The invention provides the dispersing method of thixotropic agent in a kind of resin anchoring agent, adopt the inventive method to disperse thixotropic agent, the resin-bonded mastic of gained demixing phenomenon can not occur, gummosis can not occur, final anchoring agent steady quality.
The technical scheme that the present invention adopts is following:
The dispersing method of thixotropic agent is characterized in that in a kind of resin anchoring agent, adopts the compound dispersing method of dissipation of heat, chemical dispersion and mechanical dispersion, specifically may further comprise the steps:

Promotor 0.5～2
Mineral filler 400～600
The anchoring agent prescription:
90～96 parts of resin-bonded mastics, 4～10 parts in solidifying agent.
The preparation of resin premixed material:
Keep the unsaturated polyester resin temperature in 40～60 ℃; Auxiliary rheological agents added under 200～300 rpm whipped states before silicon-dioxide disperses stir; Auxiliary rheological agents is one or more in multi-hydroxy carboxy acid's amides solution, polyvalent alcohol thiamines, the polyvalent alcohol, and add-on is 5～30% of an aerosil. The cf-that utilizes the high-shear dispersion machine to produce sucks aerosil, and high-shear disperses 10～15 min, high-shear dispersing speed 3000～5000rpm; Adding promotor stirs.
The preparation of resin-bonded mastic:
With resin premixed material and mineral filler thorough mixing, denseness is controlled at 30～50 mm.
The anchoring agent is produced:
In proportion resin-bonded mastic and the solidifying agent diplopore bag film of packing into is sealed.
Beneficial effect:
The inventive method adopts multiple dispersing method to combine; Guaranteed the abundant dispersion in resin-bonded mastic of thixotropic agent; Adopt the inventive method to disperse thixotropic agent, the resin-bonded mastic thixotropic property of gained is good, demixing phenomenon can not occur; Gummosis can not appear, final resin anchoring agent steady quality.
The concrete operations mode
