News on November 17, 2023, according to the announcement of the State Intellectual Property Office, Kingfa Technology Co., Ltd. has obtained a project called "A transparent PC/PBT alloy and its preparation method and application", the public number CN114921078B, patent application date is October 2022.
The patent abstract shows that the invention discloses a transparent PC/PBT alloy, which includes the following components by weight: 40 parts of PC resin; 25-35 parts of PBT resin; the transparent PC/PBT alloy has a thickness of 2 mm , transparency is greater than 60%, haze is less than 40%. The present invention uses various means to examine the weight average molecular weight range of PC resin and PBT resin in the transparent PC/PBT alloy after melting and blending, achieves high transparency under the condition of PC/PBT alloy with high PBT content, and solves the problem after the PBT content increases. Technical difficulties that lead to a significant decrease in the transparency of PC resin.
