一、产品特点
1.无机粉体与树脂之间的相容性不佳,经过铝酸酯偶联剂处理后,无机粉体表面会与树脂之间形成化学键,增强了无机粉体和树脂之间的界面相容性, 因此使用铝酸酯偶联剂还可以加大无机粉体的用量,提升产品质量,降低成本。
2.促进填料在树脂中的分散,改善制品的机械性能,如拉伸强度、冲击强度、抗压强度等。
3.该产品适用于各类填充母粒的生产,如碳酸钙、滑石粉、硫酸钡、硫酸钠等填料的造粒,以及各类色母粒的生产。
二、产品性能及指标
熔点(℃) | 降粘幅度(%) | 分解温度(℃ | 挥发物含量 (% ) | 外观 |
70-80 | ≥98 | 270 | ≤1 | 白色固体 |
三、使用方法
第1步:在高速捏合机处于低速状态下倒入填料,换高速加热至110C,敞口搅拌5-8分钟,使填料中的微量水分被充分蒸发,残存水分应≤0.3%才能保证无机填料的活化效果;
第2步:将偶联剂加入搅拌机内,加入量一般为填料量的1 -2% ,总的搅拌时间不得低于10分钟,使填料充分活化;
第3步:加入填料量0.5%的硬脂酸作协同剂,再搅拌2分钟即停机出料。

One, product characteristics
1. The poor compatibility between inorganic powder and resin, by aluminate coupling agent treatment, the formation of chemical bond between the inorganic powder surface and resin, reinforced between inorganic powder and resin interface compatibility, so the use of aluminate coupling agent can also increase the amount of inorganic powder,improve product quality, to reduce the cost.
2. To promote the dispersion of filler in the resin, improve the physical and mechanical properties of products, such as tensile strength, impact strength, compressive strength and so on.
3. The product is suitable for all kinds of filling masterbatch production, such as calcium carbonate, talc powder, barium sulfate, sodium sulfate, granulation filler, and the production of various kinds of color masterbatch.
Two, product performance and indicators
Melting point | Viscosity reduction range | Decomposition temperature | Volatile content | surface |
70-8- | ≥98 | 270 | ≤1 | White powder |
Three, the use of methods
1. In the high-speed kneading machine in low speed state into the filler, high-speed turn heating to 110 C, stirring exposure bake for 5-8 minutes, the trace water in the packing is fully evaporated, the remaining water should be less than or equal to 0.3% in order to ensure the quality of activated inorganic filler;
2. 2. The coupling agent into the mixer,the amount is generally1-2% of the amount of filler,the total stirring time shall not be less than 10 minutes, so that the filer fully activated;
3. Adding0.5% stearic acid as the synergist, stirring for 2 minutes, then stop discharging
Four, packaging and storage
