Description
Technical field
The present invention relates to a kind of method of modifying of organic nano imvite, particularly a kind of flame-retardant hard polyurethane foaming plastic that uses Abietyl quaternary ammonium salt-modified organic nano imvite and preparation method thereof and preparation.
Background technology
Polyurethane foam is the present heat-insulating material of performance the best in the world, because developed countries such as America and Europe pay much attention to building energy conservation, so in these countries, hard polyurethane foam has been widely used in the roof, body of wall, top ceiling, floor, door and window of buildings etc.But the density of urethane foam is little, and specific surface area is big, compares easier burning with non-foam material, and burning and decomposition produce a large amount of toxic smogs.Meeting fire can burn and decompose, and hot burst size is big during burning, produces a large amount of toxic smogs, and HUMAN HEALTH and environment are all had very bad influence.Therefore, can the flame resistivity of rigid urethane foam, security have become the important technology index that be used for lagging material.National governments also promulgate a decree and rules in succession, stipulate that clearly under some occasion, the use of polyurethane material must reach certain flame-retardant standard, and the appearance of various rules has advanced the development of flame-retarded technology greatly.
The environmental-protection flame-retardant hard polyurethane foams product of exploitation Halogen, low cigarette, low toxicity has become the focus of people's research, and the great advantage of inorganic combustion inhibitor is exactly low toxicity, low cigarette, low corrosion, and cheap.In recent years, many researchs reported organo montmorillonite urethane foam fire-retardant aspect on application, improve flame retardant type, thermostability and the mechanical property of urethane on the one hand, reduce cost on the one hand.But present enhanced effect is lasting and remarkable.Chinese patent CN200510073398.2 has reported a kind of method of heat-resisant elastic fiber polyurethane modified by diamine montmorillonite, but does not discuss the situation that this polynite is used for the flame retarded rigid polyurethane foams plastics, and preparation technology is complicated in the patent, and cost is higher.Patent CN200710068701.9 discloses a kind of polyurethane/organic montmorillonite nano composite material and preparation method thereof, main employing decamethylene diamine carries out organic modification to sodium base/original polynite of calcium base and is used for the synthetic of urethane foam, but, decamethylene diamine is that petroleum chemicals are more expensive, is unfavorable for suitability for industrialized production.Patent 200510101096.1 discloses the preparation method of the mixture of a kind of organo montmorillonite and urethane, is by the acidification sodium-based montmorillonite, obtains organo montmorillonite with the long chain alkyl ammonium salt reaction again.Then with polyether glycol, isocyanic ester, chainextender carry out compound, but be not used in the preparation of flame retarded polyurethane-foam.
Summary of the invention
For solve organo montmorillonite that prior art exists urethane foam fire-retardant aspect on application cost height, the problem of complex process, the invention provides a kind of Abietyl quaternary ammonium salt-modified organic nano imvite and its production and application, the organic nano imvite of preparation is applicable to the preparation flame-retardant hard polyurethane foaming plastic, have flame retardant properties, mechanical property and thermal stability preferably, and have bacteriostasis property.
