Abstract
The invention relates to a processing technology of a resin type composite reinforced and toughened material. The processing technology comprises the steps that polyester resin, glass fiber, organic montmorillonite and nano calcium carbonate are dried; then, a toughening agent is added, and stirring and mixing are performed; then the mixture is molten and extruded on a double-screw extruder for granulation; the granulated material is dried; finally, the dried material is subjected to injection moulding to obtain the composite reinforced and toughened material. The polyester resin is modified by the glass fiber, the organic montmorillonite and the nano calcium carbonate, the glass fiber and the toughening agent can reinforce and toughen the prepared material, and the nano calcium carbonate and the organic montmorillonite can further improve the strength of the material. Therefore, the strength of the prepared composite reinforced and toughened material is greatly improved, and an application range is wider.
