Description
The present invention is the plasticizing and calender method for producing that belongs to waste or used plastics and flyash composite product.
Raising along with development and national economy and living standards of the people, " white pollution "-waste or used plastics and " black pollution "-flyash influence strongly and are restricting development and national economy, make full use of these wastes and remove to develop high value added product, cause the extensive concern of Chinese scholars day by day and drop into considerable manpower and materials and go to develop waste recycle.
Chinese patent " 97101791.3 " discloses the invention that is entitled as " production method that flyash is made well lid ", this patent only relates to the method for flyash system well lid, this patent all has strict demand to flyash composition, granularity simultaneously, limited making full use of of flyash, its described method because do not add any anti-aging, anti-illumination, improve interface bonding, auxiliary agent such as toughness reinforcing, increase-volume, make the inaccessible service requirements of a lot of performances of product.
The plasticizing and calender method for producing that the purpose of this invention is to provide a kind of waste or used plastics and flyash composite product, use general waste or used plastics: polyethylene (PE), polyvinyl chloride (PVC), polystyrene (PS), polyester (PET) and flyash add a small amount of relevant auxiliary agent by mediating and the consolute of plasticating as main component, utilize rolling process to make sheet material.
The present invention handles flyash through silane coupling agent, increase surfactivity, helps producing reaction with the active group of waste or used plastics and auxiliary agent; When material in high temperature is plasticated process repeatedly, excited some group of small molecules auxiliary agent, formed a certain amount of free radical, these free compounds be heated with shearing action under the ion that forms act on mutually, thereby strengthened moulding-cohesive action and dispersing uniformity between ash, promoted increase-volume, the plasticization capacity of storeroom, made goods have better comprehensive performance.
It is main raw material that the present invention selects waste polyethylene (PE), polyvinyl chloride (PVC), polystyrene (PS), polyester (PET) and the thermal power plant's electrostatic precipitation flyash through screening≤80 purpose ablation amount＜10% after letter sorting, washing, granulation for use.Concrete proportioning (parts by weight) is: flyash 30-150 part and silane coupling agent 1-4 part were mediated 5 minutes down at 60-90 ℃; With waste polyethylene (PE) or polyvinyl chloride (PVC) or polystyrene (PS) or 100 parts of polyesters (PET) and ethylene 5-10 part, oxidation inhibitor 0.2-1 part, zinc oxide+tris phosphite 0.1-0.4 part, anion surfactant 1-3 part, acrylate 0.5-2 part, stearic acid 1-3 part, paraffin 5-10 part, select the respective components of auxiliary agent according to different product requirements, after mediating 10 minutes under 80-120 ℃, mediated 10 minutes down at 80-120 ℃ with the flyash of having handled, the consolute of plasticating under 120-180 ℃ prolongs at 120-170 ℃ through two roll-ins and makes sheet material again.
The sheet material that the present invention is prepared, its ultimate compression strength can reach 22-50MPa, bending strength 18-28MPa, composite bending modulus 400-800MPa, elongation at break 5-18%, tensile strength 13-25MPa, use temperature is than the corresponding improve of waste or used plastics more than 10 ℃.
The present invention utilize particle diameter only require≤80 purpose thermal power plant electrostatic precipitation flyash and waste or used plastics are compound, thereby greatly reduce the goods cost, and calendering technology is simple, easy to operate, less investment, resulting product has the good mechanical performance, and is anticorrosive, hydrophobic, shock resistance, anti-aging, wear-resisting, alternative corresponding timber product and marble products.
