Description

A kind of isocyanurate foam in high flame retardant plastics
Technical field
The present invention relates to a kind of porous plastics, particularly a kind of isocyanurate foam in high flame retardant plastics.
Background technology
Urethane foam is that isocyanic ester and oxy-compound are made through the polymerization foaming, by its hardness, can be divided into soft and hard two classes, and wherein soft is principal item.In general, it has splendid elasticity, flexibility, elongation and compressive strength; Chemical stability is good, anti-many solvents and oils; High abrasion resistance, large 20 times than natural sponge; Also having the performances such as good processibility, heat insulating ability, binding property, be a kind of cushioning material of excellent property, but price is higher.Urethane foam is general only for buffering package or the cushion material of high-grade precision instrument, valuable apparatus, high-grade artwork etc., also can be made into packaging vessel exquisite, that protectiveness is fabulous; Also can adopt foam-in-place to carry out buffering package to article.
Attapulgite is containing Shuifu County's magnesium silicate crystal mineral, has unique layer chain-like structure, unusual colloidal property and powerful adsorptive power; In addition, attapulgite has numerous nano level zeolite cavities that are parallel to excellent brilliant direction, thereby has sizable internal surface area; Its crystal grain is very little simultaneously, and outer surface area is also very large.The adsorption of attapulgite is divided into physical adsorption and chemisorption.Natural attapulgite clay comprises some dirts, if you would take off stone, kaolinite, carbonate, a small amount of particulate quartz and feldspar, may stop up duct, reduce surface-area, weakened whole physical and chemical performance, thereby colloidality, adsorptivity of making attapulgite clay etc. are greatly affected in industrial application.The method of activation modification can be removed the impurity of natural attapulgite clay, increases specific surface area, improves its absorption and ion-exchange performance, makes attapulgite clay be widely used in the fields such as absorption, decolouring, dytory, catalyzer and carrier.Contain zeolite water and crystal water in attapulgite, the water discharged when porous plastics burns can reduce the temperature of porous plastics, thereby plays certain fire retardation; In addition, contain Mg, Si element in attapulgite, the oxide compound generated during burning covers the Foam Plastic Surface starvation, thereby reaches fire-retardant purpose.
Summary of the invention
The purpose of this invention is to provide a kind of flame retardant properties high flame-retardant polyurethane expanded plastic preferably.
