Description
Technical field
The present invention relates to the surface treatment method of alkaline inorganic powder material, particularly relate to the having of rare-earth additive modification " shell one nuclear " alkaline inorganic material plastic matrix of structure and resin dedicated preparation method.
Background technology:
In plastics, rubber, printing ink and coating and the various matrix material course of processing,, used in a large number with a quasi-tradition type inorganic calcium salt or its oxide compound or the calcic alkaline inorganic material of lime carbonate as representative for the purpose that reaches increment and reduce cost.Be that the synthetic resins amount of raw material is reduced the price and risen in recent years along with the fast-developing of matrix material and with the oil, require people when guaranteeing plastics, rubber item performance, heavy addition inorganic powder filler does not have the light calcium carbonate or the water-ground limestone of appointing, and is difficult to satisfy user's requirement.Inorganic powder is carried out necessary modification become the research focus of inorganic powder material in recent years to obtain high performance active filler.
Inorganic powder materials such as lime carbonate derive from nature and return in nature, it is renewable resources, environment compatibility is good, to compare price relatively cheap with the petrochemical industry resin, develop rapidly along with inorganic powder super-refinement and process for treating surface, use rationally can not only reduce cost, and also can improve plastics performance or give new function, as flame retardant of plastic performance and environment-acceptable performance etc.
Inorganic powder modified plastics environment-friendly material has possessed 4 fundamental characteristics such as economy, usability, comfortableness and environment compatibility, be a kind of typical environment-friendly material, the inorganic powder modified plastics has become realization plastics and harmonious development leading product at present.
Study on the modification to inorganic powder, Japan is started in the twenties in 20th century, the status that is in a leading position in the world, the U.S. is in this research on the one hand also very active, and especially various coupling agents are succeeded in developing the back and played positive pushing effect to treated carbonates and at plastics, rubber, coating in industrial application.The eighties in 20th century, China is sharp with Huang, the civilian tribute of chapter etc. was not that the modified plastics expert of representative has developed a series of " inorganic filled-type multifunctional modification plastic fillers ", makes China's inorganic powder modified plastics technology be in the status of international most advanced level.But early stage research mainly is to use micro-nano carbonic acid calcium, and the filler of special construction such as talcum powder, rhombspar also is developed the toughness that is used to improve material in recent years, and magnesium hydroxide, aluminium hydroxide promptly are used to develop green bittern-free flame-proof material.Yet the inorganic powder calcium oxide is an alkaline matter, easily absorbs moisture in air, easily and acidic substance such as carbonic acid gas react.If calcium oxide is filled in the plastics, not only can absorb the moisture content of the course of processing, after the plastics use is discarded, can absorb water and carbonic acid gas, cause inorganic powder from plastics, to come off, can also in the later stage burning disposal, absorb tail gas, reduce the generation of obnoxious flavour, this will make plastics have certain environment-acceptable performance.Calcium hydroxide (Ca (OH)
2) can react with many sour gas, bringing into play great role in environment protection such as toxic and harmful leakage, the absorption of solid waste burning tail gas, disinfection and water treatment field.If can successfully add to them in the plastics in large quantities, environment-acceptable auxiliary agent as plastics uses, can when the polyolefin plastics offal treatment, have certain environment-acceptable performance, burn, prevent the generation of obnoxious flavour etc. as acid slaking, promotion.Concrete disclosed achievement has: Yang Lingmin " Tianjin rubber " (1998, delivered " siccative-oiliness calcium oxide is used for rubber and plastics " in 1:4-10); Wu Xuebin etc. " Xinjiang chemical industry " (2003,2:12-14) delivered the applied research of novel material calcium oxide in tire; The Xu Jing of Fujian Normal University etc. are in " plastic working " (2004,39 (2): 35-38) delivered " applied research of nano calcium hydroxide in the environment-acceptable plastics "; Liu Xinping etc. are at " Fujian Normal University's journal " (2006,22 (3): 68-70,117) delivered " applied research of inorganic powder calcium oxide modified poly ethylene ", and at " New Chemical Materials " (2006,34 (1): 61-62,71) delivered " research of encapsulated calcium hydroxide modified PVC ".The patented technology that relates to has: and " preparation method of plastics froth breaking masterbatch " of Yan Wanqi (200410012555.4, CN1616533,2005-05-18) etc.
Be applied to plastic cement aspect open source literature from relevant calcium oxide and the calcium hydroxide seen, mostly calcium oxide and calcium hydroxide are in plastics as absorbent masterbatch as alkaline inorganic powder, the rarely seen research report of its filling master batch as the modified matrix resin.The industrial lime carbonate that is filled in the plastics need obtain calcium oxide through behind the limestone calcination, calcium oxide just can obtain required fine particle calcium carbonate through digestion, carbonization again, if directly gained calcium oxide behind the limestone calcination is filled in the plastics, both simplified technology, again can save energy, improved society and economic benefit greatly.Calcium oxide just can obtain calcium hydroxide through digestion, and calcium hydroxide belongs to alkaline hydrated oxide, and structure and character are similar to Mg (OH)
2, Al (OH)
3, thereby can consider it as filling master batch and environment-acceptable masterbatch, also can be used as flame-retardant master batch and use.
How to develop " economy, the functional and feature of environmental protection coordinating and unifying resin dedicated ", the inorganic powder modified plastics is the best means that realizes its economy and the feature of environmental protection.Rare earth element is to be arranged in periodic table of elements three races, the lanthanon of period 6, also comprises the scandium of similar performance and the various elements of yttrium.Because it has the special electron structure of 4fx5d16s2, the electricity price height, radius is big, polarization force is strong, chemical property vivaciously reach can hydrolysis etc. character, so its application is very extensive.Utilize rare earth modified inorganic powder to realize that the multifunction of inorganic powder has its tangible technical superiority than by modified rubber, has more distinct Chinese characteristics simultaneously.
