Description
Technical field
The present invention relates to a kind of halogen-free flame-retardant hot-melt pressure sensitive adhesive tape and preparation method thereof.
Background technology
Along with emerging in an endless stream of event of fire, fire retardant material more and more obtains paying attention to, and industries such as building, electronics all require material to have excellent flame-retardant performance, to reduce the danger that fire takes place.
Usually, utilize Organohalogen compounds and Sb
2O
3Composite use can reach good flame retardancy under the less situation of addition.But this type of fire retardant material can produce and has corrodibility and toxic hydrogen halide in a large number in combustion processes, and bigger to the harm of human body, according to statistics, the lethal ratio of fire sootiness is up to 78.9%.Therefore, halogen-free flame retardants obtains the favor of more and more fire retardant material producers, wherein, and with being most widely used of metal hydroxide combustion inhibitor and expansion type flame retardant.
Simultaneously,, relate to all respects such as daily life, industrial application, export trade packing, and it is few to have the pressure sensitive adhesive kind of flame retardant resistance because the pressure sensitive adhesive product-use is extensive, and also very few in the research in this field both at home and abroad.At present, business-like fire-retardant pressure-sensitive adhesive film is mainly used in electron trade and automobile industry, as the 5011N etc. in day east.
Usually, fire-retardant Pressuresensitive Tape generally has two types, be a kind of be that to rely on the flame retardant resistance of base material to realize fire-retardant, introduced the Pressuresensitive Tape that a kind of halogen-free flameproof base material and pressure-sensitive adhesive layer are formed as patent 03133048.7, this adhesive tape must guarantee flame retardant resistance by the base material of fire retardant polyolefin.And for example patent 03101420 discloses a kind of odorless and halogen-free flame-retardant pressure-sensitive adhesive tape that has the cloth base material, described two-layer all by tackifier resins, fire retardant (metal hydroxides and inorganic fire-retarded auxiliary agent) and the acquisition of employing aminoalkyl group organoalkoxysilane sulfurized natural rubber based elastomeric, its base material is the cloth base material through fire-retardant finish by using the inflammable cloth base material of natural rubber based fire-retardant combination dipping to obtain preferably, and the fire-retardant rank of adhesive tape satisfies UL-510FR combustion test flame-retardant standard.Another kind is that the pressure sensitive adhesive composition has flame retardant resistance, a kind of acrylic acid series pressure-sensitive adhesive tape halogen-free flame retardants and method thereof have been introduced as patent 200510028764.2, by with joining in the acrylate pressure sensitive adhesive after halogen-free flame retardants and the organic solvent grinding, obtain Pressuresensitive Tape through coating.But this method long processing time (2～4 hours), and owing to the content of fire retardant reaches more than 25% at least, so need a large amount of solution in the preparation process, cause inefficiency and not environmental protection.
Because most pressure sensitive adhesive goods adopt solution coat production, as polyacrylate(s) pressure sensitive adhesive and part rubber-like, use tank solution in process of production, contaminate environment not only, harmful, and increased the danger and the complicacy of operating, improved energy consumption.
