Abstract
The invention provides a method of preparing SBS/calcium carbonate nano composite material, which includes steps: adding nano calcium carbonate and surface treatment agent into organic solvent and dispersing for 1-20 min at 10-65 DEG C to obtaining mixed emulsion, adding the mixed emulsion into SBS glue liquid and dispersing for 10-30 min at 30-70 DEG C, boiling glue, eliminating the organic solvent and obtaining the SBS/calcium carbonate nano composite material; or adding the nano calcium carbonate directly into the SBS glue liquid and dispersing for 30-60 DEG C, boiling glue, eliminating the organic solvent and obtaining the SBS/calcium carbonate nano composite material. The nano calcium carbonate particles in the composite material reach to nano-scale dispersion, thereby exerting action of filling and improving SBS capability of inorganic nano particle, increasing abrasion resistance of the composite material and reducing cost.
Description
Technical field
The present invention relates to a kind of preparation method of SBS/ calcium carbonate nano composite material.
Background technology
Existing rubber/CaCO
3The preparation method of nano composite material adopts completion method, wherein is divided into compounding filled method and emulsion and fills coprecipitation method.The former is with nanometer CaCO on rubber mixing machine
3Prepare with the solid rubber blend; The latter is with nanometer CaCO
3Add latex and mix, prepare through processes such as coprecipitated, dryings.Adopt completion method to prepare nanometer CaCO
3/ rubber composite, nanometer CaCO
3Degree of scatter in rubber matrix is relatively poor, and the performance of material is lower, employed nanometer CaCO
3Powder all will be through preventing to reassemble and the stability processing, and the latex coprecipitation method also will make nanometer CaCO
3Again dry for the second time, cause the preparation cost of matrix material higher.
And there is not report to use nanometer CaCO at present as yet
3The method of modified SBS.
Summary of the invention
The preparation method who the purpose of this invention is to provide a kind of SBS/ calcium carbonate nano composite material, thus the effect of SBS performance is filled and improved to the performance inorganic nano-particle, improves its wear resistance, reduces cost simultaneously.
The preparation method of nano-calcium carbonate of the present invention/SBS matrix material joins nano-calcium carbonate, surface treatment agent in the organic solvent, disperseed 1～20 minute down at 10～65 ℃, then mixed emulsion is joined in the SBS glue and disperseed 10～30 minutes down in 30～70 ℃, boil glue, remove organic solvent, obtain the SBS/ calcium carbonate nano composite material; Or nano-calcium carbonate directly joined disperseed in the SBS glue 30～60 minutes, boil glue, remove organic solvent, obtain the SBS/ calcium carbonate nano composite material.
Wherein the add-on of each component is a benchmark with 100 parts of the dried glue of SBS, and the parts by weight of other components are as follows:
1 part～10 parts of nano-calcium carbonates
