Abstract

The invention provides a composition for toughening glass fiber reinforced polycarbonate alloy, which comprises thermoplastic matrix resin, polyamide, phosphorus halogen-free flame retardant, glass fiber and fluororesin. According to the composition for toughening glass fiber reinforced polycarbonate alloy, the polyamide is added into the glass fiber reinforced polycarbonate alloy to toughen the glass fiber reinforced polycarbonate alloy, so that the glass fiber reinforced polycarbonate alloy product with a certain thickness can not be broken when being bent by 180 degrees; and the composition for toughening glass fiber reinforced polycarbonate alloy enhances the toughness of the glass fiber reinforced polycarbonate alloy on the premise of keeping other favorable properties.

Description

【Technical field】 [0001] The invention relates to a formula for glass fiber reinforced polycarbonate alloy, in particular to a formula for toughening glass fiber reinforced polycarbonate alloy. 【Background technique】 [0002] In recent years, glass fiber reinforced polycarbonate alloys have become more and more widely used. However, due to the high rigidity of glass fiber-reinforced composite materials, the toughness of glass fiber-reinforced polycarbonate alloys is severely reduced, and molded products are easily broken and brittle, which limits the use of glass fiber-reinforced polycarbonate alloys in daily furniture and offices. Application on automation products. Therefore, the improvement of the toughness of glass fiber reinforced polycarbonate alloys has become an urgent problem to be solved. [0003] At present, the tougheners used in glass fiber reinforced polycarbonate alloys are mainly acrylates and elastomers. Acrylic esters are mainly MBS, and elastomers are m...
