產品介紹

一、產品特點

1.無機粉體與樹脂之間的相容性不佳,經過鋁酸酯偶聯劑處理后,無機粉體表面會與樹脂之間形成化學鍵,增強了無機粉體和樹脂之間的界面相容性, 因此使用鋁酸酯偶聯劑還可以加大無機粉體的用量,提升產品質量,降低成本。

2.促進填料在樹脂中的分散,改善制品的機械性能,如拉伸強度、沖擊強度、抗壓強度等。

3.該產品適用于各類填充母粒的生產,如碳酸鈣、滑石粉、硫酸鋇、硫酸鈉等填料的造粒,以及各類色母粒的生產。

三、使用方法

第1步:在高速捏合機處于低速狀態下倒入填料,換高速加熱至110C,敞口攪拌5-8分鐘,使填料中的微量水分被充分蒸發,殘存水分應≤0.3%才能保證無機填料的活化效果;

第2步:將偶聯劑加入攪拌機內,加入量一般為填料量的1 -2% ,總的攪拌時間不得低于10分鐘,使填料充分活化;

第3步:加入填料量0.5%的硬脂酸作協同劑,再攪拌2分鐘即停機出料。

四、包裝與儲存

本產品為非危險品,請遠離火源存放。

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.

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

This product should be stored in the ventilated and dry place, pay attention to moistureproof and fireproof, and the shelf life is 6 months

Net weight per bag: 25kg
