Abstract

The invention relates to one kind of preparation methods of the potent modified fillers strong magnesium powder, the method's technological process is: Taking light burning magnesium powder and talcum powder from raw materials, the original powder shares proportion according to weight , the ratio of the light burning magnesium powder is 40-70, the ratio of the talcum powder is 60-30; After weighing accurately, throwing them into the high-speed mixer to stir under higher temperature, the temperature is controlled below 100 degree C, simultaneously spraying into surface treatment reagents ; The related surface treatment reagent refers to one kind or the combination of two kinds of the silicon hydride resin acceptor and the stearic acid, the amount is 0.3-0.5% of the total weight of the light burning magnesium powder and the talcum powder. Comparing with the existing technology, the benefits of this invention consists: realizing the extensive and functional application of composite materials, reducing the cost of high-quality fillings, using mineral resources more effectively.

Description

technical field [0001] The invention relates to an ultra-fine inorganic mineral filler and a preparation method of magnesium powder, a powerful modified filler. Background technique [0002] With the rapid development of the world economy, especially the rapid rise of the plastic industry, the product quality of non-metallic mineral powder is required to develop in the direction of high-grade, ultra-fine and modified. At present, due to the substantial increase in the price of raw materials, it is not only necessary to achieve a high filling amount of the product, but also to reduce the cost of the product. However, the finished product of pure magnesium powder is very expensive, and it is difficult to achieve the physical properties of filled products. Contents of the invention [0003] On the basis of summarizing the application properties of various non-metallic mineral products, the present invention provides a preparation method of a powerful modified filler magnesiu...
