设计改性塑料的配方

One
树脂品种的选择
Selection of resin varieties
树脂要选择与改性目的性能最接近的品种,以节省加入助剂的使用量。如耐磨改性,树脂要首先考虑选择三大耐磨树脂PA、POM、UHMWPE;再如透明改性,树脂要首先考虑选择三大透明树脂PS、PMMA、PC。
The resin should select the most suitable varieties with modified purpose so as to save the amount of additives. If the wear-resistant modification, the resin should first consider the choice of three major wear resistant resin PA, POM, UHMWPE; again such as transparent modification, the resin should first consider the choice of three large transparent resin PS, PMMA, PC.

树脂牌号的选择
Selection of resin grades
同一种树脂的牌号不同,其性能差别也很大,应该选择与改性目的性能最接近的牌号。如耐热改性PP,可在热变形温度100~140℃的PP牌号范围内选择,我们要选用本身耐热120℃的PP牌号。
Different brands of the same resin have great difference in their properties. They should choose the brand with the closest performance. If the heat-resistant modified PP, can be in the hot deformation temperature of 100 ~ 140 degrees within the range of PP grades, we want to choose their own heat-resistant 120 degrees of PP grades.

树脂流动性的选择
Selection of resin fluidity
配方中各种塑化材料的粘度要接近,以保证加工流动性。对于粘度相差悬殊的材料,要加过渡料,以减小粘度梯度。如PA66增韧、阻燃配方中常加入PA6作为过渡料,PA6增韧、阻燃配方中常加入HDPE作为过渡料。
The viscosity of various plasticizing materials in the formula should be close to ensure processing fluidity. For different materials with different viscosity, the transition material should be added to reduce the viscosity gradient. For example, PA6 is often added as toughening agent in PA66 toughening and flame retardant formulations. HDPE is often used as a transition material in PA6 toughening and flame retardant formulations.
