Description
Technical field
The present invention relates to a kind of synthetic materials and fire-retardant halogen efficient flame-retarding agent composition and method of making the sames of textiles such as various polyolefine, nylon, urethane and polyester of can be used for, particularly relate to a kind of novel benzoguanamine carboxyethyl phenyl phosphinic acid condenses and be main flame retardant, through with organophosphate and trimeric cyanamide and/or the composite halogen efficient flame-retarding agent composition and method of making the same of its verivate; Compsn of the present invention is particularly useful for polyester and nylon engineering plastic is flame-retardant modified with halogen efficient flame-retarding agent compsn, and a kind of halogen efficient flame-retarding agent compsn of the present invention has highly effective flame-retardant property, high workability, fire retardant and characteristics such as do not separate out; According to the purposes needs, can add an amount of oxidation inhibitor, photostabilizer and processing aid etc. simultaneously, also can mix use with other halogen flame and inorganic combustion inhibitor.
Background technology
Since the eighties in 20th century, fire retardant has become the maximum auxiliary agent of synthetic materials consumption that is only second to softening agent.Along with expanding economy, people have had large increase to environmental protection and awareness of safety, and ecotope and value of life are also more paid close attention to.Traditional halogenated flame retardant is used for the production of fire retardant material in a large number because its flame retarding efficiency is high, but when burning, produces a large amount of smog and deleterious corrosive gases because halogen is flame retardant products, hinders rescue and evacuating personnel, causes secondary disaster to take place.Therefore, halogen is that the application of flame retardant products is restricted.Halogen-free flame retardants is used widely owing to have environmentally friendly characteristics such as low cigarette, low toxicity.Use efficient, low cigarette, halogen-free flame retardants nontoxic or low toxicity will become the inexorable trend of following fire retardant material development.Inorganic in recent years filler and fire-retardant and phosphorus flame retardant receive common concern.
Phosphorus flame retardant enjoys attention because flame retarding efficiency is high in the halogen-free flame-retardant field.Traditional phosphorus flame retardant great majority have volatility, and therefore defectives such as facile hydrolysis develop the macromole low volatility, and the phosphorus flame retardant of facile hydrolysis is not the emphasis of developing from now on.Chinese patent ZL200710048573 has described the esterification of tetramethylolmethane and carboxyethyl phenyl phosphinic acid, and its reaction product is the carboxyethyl phenyl phosphinic acid pentaerythritol ester, contains phosphorus in the product simultaneously and becomes carbon-based group with tetramethylolmethane.Chinese patent ZL200410069309 has described the compound method of melamine salt of pentaerythritol bis (dihydrogen phosphate).Yet, wherein between synthetic reaction 7～10 hours that need of product phosphoric acid pentaerythritol ester, the reaction times is long, and solvent is that benzene is big to environmental influence.
Chinese patent CN101928448A described a kind of with metal phosphinate (comprising hypo-aluminum orthophosphate, magnesium hypophosphite, calcium propionate, zinc hypophosphite) with contain nitrogen combustion inhibitor (comprising melamine polyphosphate, melamine cyanurate, melem, melamine pyrophosphate) and carry out composite obtained flame-retardant compsn; After itself and polyester blend are obtained a kind of preparation method of nano composite flame-retardant reinforced polyester engineering plastic, this technology overcomes that the halogen containing flame-retardant environmental hazard that the polyester reinforcement modification exists is big, the inorganic combustion inhibitor addition is high, the shortcoming of material physical property difference; Yet multi-section is divided into metal inorganic salt in this flame retardant composition; Separate out easily; Materials processed performance and end article mechanical property are had very big negative interaction, and this invention adopts a kind of modified Nano additive to solve this problem, but this additive preparation complex process; Industrial production is difficult for realizing that practical ranges is limited.
Chinese patent CN101280105A has described a kind of surface treated hypophosphite and silane mixture as fire retardant; Nylon 66 is carried out modification made the high machinery performance halogen-free anti-flaming matrix material; Yet; This fire retardant needs in the preparation process through grinding, pyroprocessing repeatedly, complicated steps; And this composite flame-retardant agent flowability is bad, and metal-salt is big to the physics and the chemical property influence of polyester and nylon products, makes that the material over-all properties is undesirable.
For this reason, be necessary to explore Halogen and more efficient, the flame-retardant system that high workability, difficulty are separated out, reaching certain fire-retardant rank, and it is to processing characteristics, the novel flame-retardant system that the material comprehensive mechanical property does not have a negative impact after the modification.
