Abstract
The invention relates to the technical field of high-temperature thin films, in particular to a color-changed protection bag used under high-temperature environment. Compared with the existing technology, the color-changed protection bag used under high-temperature environment uses polyhexamethylene diamine adipate as a base body material, heat stabilizer and slipping agent in a certain proportion are added, the protection bag capable of high temperature resistance is manufactured through extrusion blow molding method and is mainly used in the industries of solvent recovery, disinfection, thermophilic digestion and the like; the protection bag is color-changed as the effect; and the protection bag is darkened after being used so that high temperature heating is efficient. The color-changed protection bag used under high-temperature environment has the advantages that the color-changed protection bag is resistant to high temperature and can withstand for more than 2h at the temperature of 220 DEG C; the color-changed protection bag is safe and can be used for food contact; and the color-changed protection bag is marked so as to efficiently distinguish the using effect of the protection bag.
Description
Technical field
The present invention relates to high temperature film technical field, particularly a kind of variable color protecting band for hot environment.
Background technology
In the hot environments such as solvent recovery, sterilizing, thermophilic digestion, the change of temperature is extremely important, and protecting band in these hot environments use as not having color to change, by very difficult judgement, it has been heated to any program, therefore industry be badly in need of a kind of resistant to elevated temperatures and also can in heat process the protecting band of changes colour, its program heated can be known by the color change watching protecting band.In addition in conventional solvent reclaims, clean reclaiming scrap is a difficult job, because of solvent huge number, usual distillation heating-up temperature is higher, can to 220 DEG C, designing a protecting band for hot environment effectively will reduce scavenging period, extend reclaiming scrap service life.Hot air sterilization is a method emerging in sterilizing, has more thoroughly advantage at higher temperature compared with moist heat sterilization, and general sterilising temp is at 180 DEG C-220 DEG C, and conventional plastic packaging bag cannot meet the demands, and needs high temperature resistant protecting band.The thermophilic digestion of food is a common cooking method, especially in the appliance applications such as baking box, micro-wave oven, easily occurs that juice splashes during heating of food, pollutes electrical equipment inwall, and cleaning is abnormal difficult,
Before electrical equipment heating, food is inserted in special protecting band, can effectively avoids the juice splashed to pollute inwall.
Summary of the invention
For the defect in solution prior art existing for composite material use procedure and problem, provide a kind of variable color protecting band for hot environment.
The technical scheme that the present invention adopts for its technical matters of solution is: the variable color protecting band for hot environment of the present invention color in heat process produces deepens change gradually, described variable color protecting band take PA 66 as basis material, add a certain proportion of heat stabilizer and slipping agent, manufactured by extrusion blow molding processes shaping.
The ratio that described PA 66, heat stabilizer and slipping agent gather is: hexamethylene diamine adipate: 100 parts; Heat stabilizer: 2-8 part; Slipping agent: 0.1-1.0 part.
Described basis material PA 66 comprise in wire drawing level, extrusion molding level, general purpose grade one or more.
Described heat stabilizer is compound nantokite.
Described slipping agent comprise in erucyl amide, oleamide, silicon-containing compound one or more.
Described variable color protecting band is applied in solvent recovery, sterilizing, thermophilic digestion.
The invention has the beneficial effects as follows: compared with prior art, variable color protecting band for hot environment of the present invention take PA 66 as basis material, add a certain proportion of heat stabilizer and slipping agent, can resistant to elevated temperatures protecting band by extrusion blow molding processes manufacture, be mainly used in the industries such as solvent recovery, sterilizing, thermophilic digestion, this type of protecting band is using color change as the sign of effect, darken after using and show that high-temperature heating is effective, tool has the following advantages: temperature tolerance: can bear 220 DEG C of environment more than 2 hours; Safety: can be used for Food Contact; Labeled: effectively distinguish protecting band result of use.
Detailed description of the invention
Variable color protecting band for hot environment of the present invention is basis material with PA 66, adds a certain proportion of heat stabilizer and slipping agent, and the ratio that PA 66, heat stabilizer and slipping agent gather is: hexamethylene diamine adipate: 100 parts; Heat stabilizer: 2-8 part; Slipping agent: 0.1-1.0 part.Basis material PA 66 comprise in wire drawing level, extrusion molding level, general purpose grade one or more, heat stabilizer is compound nantokite, slipping agent comprise in erucyl amide, oleamide, silicon-containing compound one or more.
Variable color protecting band for hot environment of the present invention manufactures shaping by extrusion blow molding processes, in hot environment use procedure, color produces deepens change gradually, use front protecting band for light green, gradually become in Dark Green, brown, brown-green after applied at elevated temperature one or more, the change of its color is the length of careless time of heat and becomes molten gradually, can absolutely prove the validity of product high-temperature heating like this.
Variable color protecting band for hot environment of the present invention is mainly used in the industries such as solvent recovery, sterilizing, thermophilic digestion, compared with prior art, it greatly reduces the cost of protecting band in prior art, and be there is the effect being indicated protecting band result of use by color change in time, and its product tensile property improves 10-30%, fracture elongation improves 20-30%, price is about the 50-70% of similar film, and possesses following advantage: temperature tolerance: can bear 220 DEG C of environment more than 2 hours; Safety: can be used for Food Contact; Labeled: effectively distinguish protecting band result of use.
The nonrestrictive description according to embodiments of the invention describing the present invention property, but should be understood that when not departing from relevant scope defined by the claims, those skilled in the art can make and changing and/or amendment.
Claims (2)
1. the variable color protecting band for hot environment, it is characterized in that: variable color protecting band color in heat process produces deepens change gradually, described variable color protecting band take PA 66 as basis material, add a certain proportion of heat stabilizer and slipping agent, manufactured by extrusion blow molding processes shaping; The ratio of described PA 66, heat stabilizer and slipping agent is: hexamethylene diamine adipate: 100 parts; Heat stabilizer: 2-8 part; Slipping agent: 0.1-1.0 part; Described basis material PA 66 comprise in wire drawing level, extrusion molding level, general purpose grade one or more; Described heat stabilizer is compound nantokite; Described slipping agent comprise in erucyl amide, oleamide, silicon-containing compound one or more.
