oc ~ 170
oCdry 1-3 hour; Calcium carbonate is processed as granularity & lt; The powder of 4um, is placed in loft drier 105
oc ~ 170
oCdry 1-3 hour; Attapulgite powder and calcium carbonate powder are placed in stirrer by 1:20 ~ 1:10 mass ratio, add again attapulgite powder and Paris white weight and 1% ~ 5% stearic acid, under temperature is no more than 80 ° of C situations, 1500-3000r/min rotating speed stirs 5-10min, obtains recessed soil/Calcium Carbonate Composite Fillers.Preparation method of the present invention is simple, raw material is all the inorganic mineral material be easy to get, non-environmental-pollution, threadiness and the recessed soil of tool flexibility and particulate state and the calcium carbonate compound of tool rigidity, according to collaborative enhancing principle, add to fill out in polyurethane leather and promote the apparent of polyurethane leather and mechanical property.
Description
Technical field
The present invention relates to the method utilizing ceramic compound to prepare polyurethane leather filler, belong to the Application Areas of ceramic in macromolecular material, be specifically related to the recessed soil/Calcium Carbonate Composite Fillers preparation method for polyurethane leather.
Background technology
Attapulgite, as one dimension natural nano structured material, effectively can improve the over-all properties of macromolecular material, and related compound research is the focus of recessed native research for application and development, is also the high-valued important growth point of recessed local products industry.There are some researches show that recessed soil fills mechanics and the apparent property that effectively can improve polyurethane leather.In addition, granular calcium carbonate because of the U.S. thing of its valency honest and clean, be the filler that low and middle-grade polyurethane leather is conventional.
Summary of the invention
The object of the invention is to: a kind of recessed soil/Calcium Carbonate Composite Fillers preparation method for polyurethane leather is provided, threadiness and the recessed soil of tool flexibility and particulate state and the calcium carbonate compound of tool rigidity, according to collaborative enhancing principle, add to fill out in polyurethane leather and promote the apparent of polyurethane leather and mechanical property.
Technical solution of the present invention is that this recessed soil/Calcium Carbonate Composite Fillers preparation method comprises the following steps: the powder recessed for the raw material of attapulgite mass content >90% soil being processed as granularity <2um, length-to-diameter ratio >6, is placed in loft drier 105
oc ~ 170
othe dry 1-3 hour of C; Calcium carbonate is processed as the powder of granularity <4um, is placed in loft drier 105
oc ~ 170
othe dry 0.5-1 hour of C; Attapulgite powder and calcium carbonate powder are placed in stirrer by 1:20 ~ 1:10 mass ratio, add again attapulgite powder and Paris white weight and 1% ~ 5% stearic acid, under temperature is no more than 80 ° of C situations, 1500-3000r/min rotating speed stirs 5-10min, obtains recessed soil/Calcium Carbonate Composite Fillers.
The invention has the advantages that:
1. raw material is all the inorganic mineral material be easy to get, and makes full use of the good characteristic of bi-material;
2. preparation method is simple, non-environmental-pollution;
3. compounded mix is safe and reliable, and the tensile strength of polyurethane leather can be made to promote more than 20%, and elongation at break promotes more than 30%, and the resistance to performance that circumnutates also significantly improves.
