Abstract
The invention provides the water-soluble flame retardant of natural fibre products.This fire retardant is based on APP and ammonium sulfate, and tetraboric acid hydrogen ammonium prevents agent as yellowing.The invention provides the paper product that require to keep WATER RESISTANCE delay dry processing method and to not requiring that the WATER RESISTANCE goods add the processing method of bleeding agent, improved the permeability of fire retardant liquid, thereby reached good flame-retardant effect, and kept the flexility of fibre.
Description
The present invention relates to the flame treatment technology and the using method thereof of natural fibre products.
Along with the modernization of interior decoration, some natural fabric decorated articles need carry out flame treatment, wallpaper for example, artificial leather base fabric, hair hemp floor mat and electric blanket etc.They do not require washability, but require to have certain flame retardant effect.This is an effective fire prevention measure in skyscraper and public place building.
Adopting diammonium hydrogen phosphate, ammonium dihydrogen phosphate (ADP) and ammonium sulfate in the known BP 1602720 is main raw material preparation fire retardant.Yet the viscosity of ammonium phosphate is relatively poor, and is little to the miscible adhesive attraction of ammonium sulfate, and fiber, especially cloth and paper after handling can become fragile, and folding resistance obviously descends, and crystallization comes off easily when rubbing, the jaundice easily of being heated of the paper product after handling simultaneously.
Adopting APP in the Japan Patent (clear 56-10582) is main raw material preparation fire retardant.Because APP is the sticking material of macromolecule, the paper product intensity of handling through it does not reduce, and folding resistance is also better, crystallization difficult drop-off when rubbing.But the cost of raw material of fire retardant has but improved greatly, is unfavorable for applying.Although and in its scheme, added pollopas and prevent the paper product flavescence of being heated, the results showed DeGrain.
Be defective and the deficiency that overcomes above-mentioned fire retardant, the objective of the invention is to utilize the ammonium sulfate price to hang down and prepare a kind of water-soluble flame retardant with the good advantage of APP viscosity, so that natural fibre products is carried out effective flame treatment, and keep the good flexility of its goods.
Characteristics of the present invention are to have selected most economical water-soluble flame retardant ammonium sulfate and the sticking APP mixed preparing of macromolecule for use, thereby it is strong both to have improved ammonium sulfate crystallization, influences the fibre performance defect, has reduced cost again significantly.Simultaneously prevent agent-tetraboric acid hydrogen ammonium, can prevent the paper product flavescence of being heated effectively because of containing yellowing.
Another characteristics of the present invention are that solids content is 40~45% in the flame retardant solution.
Raw material weight proportioning of the present invention is an APP: ammonium sulfate: tetraboric acid hydrogen ammonium=100: (10~500): (0~20).
Preparation example of the present invention:
The synthetic APP 100kg of fusion is blended into 30% ammonium sulfate 340kg, stirring and dissolving.Add 15kg boric acid and ammoniacal liquor again and make the pH value of solution transfer to 6~6.5, convert water at last to 500kg.At this moment, APP: ammonium sulfate: tetraboric acid ammonium=100: 100: 10.
When the present invention was used for paper product, its weight ratio is APP: ammonium sulfate: tetraboric acid hydrogen ammonium=100: (10~500): (0.1~20), optimum weight ratio were 100: (50~200): (0.1~15). When being used for cotton and hair hemp floor mat, its weight ratio is APP: ammonium sulfate=100: (10~300), best proportioning are 100: (50~150). Be used for pp carpet, when the burlap face was fire-retardant, its weight ratio was APP: ammonium sulfate=100: (10~500), best proportioning are 100: (200~300).
The flame-proof treatment method that the present invention is used for fibre mainly is to pad at flame retardant solution, then oven dry. Its characteristics are that the concentration of the retardant solution of dipped article calculates by the liquid absorption of goods, are advisable as 13~15% to keep goods to contain the fire retardant effective dose. When processing does not require maintenance water-resistance goods, can add the penetrating agent JFC (aliphatic alcohol polyoxyethylene) that accounts for retardant solution (0.1~0.5) %. Have a water resisting property by force in processing, and when still keeping the paper product of water-resistance after require processing, can improve dipping temperature between 50 °~80 ℃, and in the measure of padding rear employing and delaying to dry, namely between 50 °~80 ℃, delay 1~10 second post-drying, also can deposit at normal temperatures again oven dry after 0.5~1 hour.
With the goods after this method processing, feel changes little, and intensity does not reduce, and rubs rear no salt crystallization and comes off. Improve the permeability of fire retardant, reached good flame retardant effect.
The goods of the embodiment 1-flame treatment 80g/m that attaches most importance to2The body paper of plastic wall paper, require to keep water-resistance after processing.
Select fire retardant 60kg, wherein APP contains 20%, and ammonium sulfate contains 20%, and tetraboric acid hydrogen ammonium contains 2%, and solid content is 42%. Add water 40kg and stir, impregnated paper is after 3~5 seconds under 60 °~70 ℃ conditions, and mangle paper increases weight 55%. Enter rear row's drying cylinder again and be warming up to 100 °~110 ℃ to oven dry second surplus the front-seat drying cylinder of dryer keeps 70 °~80 ℃ 10, finishes the flame treatment overall process. Paper product test result after treatment: oxygen index (OI) is that the domestic China National Light Industrial Products Department of 35(is defined as 30), tensile strength increases by 5~10%, 200 ℃ bake 60 seconds after, the paper product whiteness does not more add the paper product whiteness that tetraboric acid hydrogen ammonium processes and improves 18%.
The goods of embodiment 2-flame treatment are 20
S* 20
SDyed sheeting.
Select for use and contain APP 25%, the fire retardant of ammonium sulfate 15%.Earlier add the 0.1kg penetrating agent JFC with 77kg water, the back that stirs adds above-mentioned fire retardant 23kg, stirs evenly again, and with cloth immersion liquid mangle after 3~5 seconds, making its liquid content is 70%, oven dry then.Cloth method of testing and result after the processing: dried cloth was vertically lighted 12 seconds with liquefied petroleum gas 38mm flame, and average char length is 87.7mm, remove flame after, no ashes do not burn.The feel of cloth variation simultaneously is not obvious, and brute force does not reduce.Rubbing no crystallization comes off.
Embodiment 3-handles polypropylene fibre fiber crops lining carpet.
The 0.2kg penetrating agent JFC is added in the 50kg water, add again after the dissolving and contain APP 10%, the fire retardant 100kg of ammonium sulfate 30%.Every square metre of fire resistant fluid 150g that spray is prepared, behind the hot blast drying.Method of testing after the processing and result: use the liquefied petroleum gas flame, lighted the burlap face 10 seconds with 45 from handling carpet bottom, back, remove flame after, the burlap face does not burn.
