Abstract
The invention discloses a novel water-soluble textile product flame retardant comprising, by mass: 42-44% of water, 26-30% of phosphoric acid, 4-6% of magnesium hydroxide, and 22-24% of urea. The phosphoric acid is industrial-grade phosphoric acid with a concentration of 85%, the magnesium hydroxide is industrial-grade powder with a purity no lower than 99.5%. A preparation method of the flame retardant with the components comprises the steps that: water accounting for 20-22% of a total mass is added into a reaction vessel; 26-30% of phosphoric acid is added slowly; the reaction vessel is heated to approximately 65 DEG C; 4-6% of magnesium hydroxide is added, and the mixture is stirred for 10-15min; 22-24% of urea is slowly added; when the temperature of the solution is reduced to 53-55 DEG C, 20-22% of water is added for diluting; and the mixture is stirred for 30-40min until the solution is cooled to normal temperature. (1) The flame retardant provided by the invention does not contain halogen element, antimony or formaldehyde, and other heavy metal, such that damages to human body is greatly reduced. The flame retardant is water-soluble, and the processing method is simple. With the flame retardant, flame-retardant finishing can be carried out upon a textile product through manners of soaking, spraying, and padding. With the flame retardant, a uniform coating effect and immersion-resistant flame-retardant effects can be achieved on the textile product. With the flame retardant, the textile product has a soft texture, and is air-permeable.
Description
Technical field
The invention belongs to the fire retardant technical field, water-soluble flame retardant for textile that is specifically related in textiles, use and preparation method thereof.
Background technology
Textiles is the requisite part of living every day, and it also has been widely used in various fields, and its anti-flammability is one of serious problems of concern in the industrial production manufacturing process.
The fire retardant that at first is used for protective textile must be to being overall safety on environment and the life Neo-Confucianism, compatible with fabric, do not damage aesthetic property and the quality of fabric, such as keeping fabrics feel soft, influence degree will drop to the end after surface quality was processed by fire retardant, and widely soaking-resistant or water cleaning performance must be arranged.This just requires to be applicable to textile treatment, family expenses sofa cloth and the furniture that particularly can not change in the operating period at product, and the required employed fire retardant of coating fabric in the fields such as metope can also satisfy the flammable requirement of this area after process clear water or scouring.In the prior art, usually adopt flame retardant for textile such as United States Patent (USP) 3955032 and 4600606 that adhere to the brominated preparation of aromatics of matrix by adhesive.Because it comprises brominated halogen, causes easily its remaining trace on deep-colour fabric, and because halogen family has larger damage, corrosion effect to human body, also large to ambient influnence, must the new fabric flame-retardant agent composition of development.
In recent years, several antimony based compounds are used in the prescription of fabric flame-retardant agent, are generally and contain Sb
2O
3, Sb
2O
5, Na
3SbO
4Deng the oxide that contains antimony, because the cost of antimony containing compounds is higher, and it is in the residual injury that can cause equally human body of textile surface, and therefore, the fire retardant of the type also needs to improve.
Use the field for some special textiles; the textiles that applied fire retardant is cleaned by the surface or immersion removal surface blot afterwards in pollution; and it is aforesaid halogen-containing or contain the antimony fire retardant after cleaning through the surface or soaking; usually can precipitate in the water; cause anti-flaming function to weaken or disappear; and; above-mentioned fire retardant is the solution of water-insoluble matter normally; after being coated in fabric face; usually residual have a vestige; for improving the anti-soaking performance of existing textiles fire retardant, and reduce the textiles remaining trace after using, the present invention proposes water-soluble textiles fire retardant of a kind of new formulation and preparation method thereof.
Summary of the invention
The present invention is directed to and existing contain the halogen family element and the antimony containing compounds fire retardant is detrimental to health, cost of manufacture is high, through easily dissolving after soaking, and non-water-soluble defective, a kind of water-soluble flame retardant for textile that does not contain halogen family element or antimony is proposed, can satisfy fire-retardant, the requirement of anti-cleaning, anti-immersion.
Technical solution of the present invention for achieving the above object is, the composition that this fire retardant of new type water-solubility flame retardant for textile comprises is: water 42～44%, phosphoric acid 26～30%, magnesium hydroxide 4～6%, urea 22～24%, phosphoric acid wherein is that concentration is 85% PHOSPHORIC ACID TECH.GRADE, and magnesium hydroxide is the technical grade powder, and purity is not less than 99.5%; Above-mentioned percentage is mass percent.
The retardant solution of above-mentioned composition is water-soluble solution, and pH value is 7.0～8.0.
The invention still further relates to the fire retardant preparation method of above-mentioned composition, its preparation process is: add the water that accounts for gross mass 20～22% in reactor, then slowly add 26～30% phosphoric acid, about heating reactor to 65 ℃, then add 4～6% magnesium hydroxide, stirred 10～15 minutes, slowly add again 22～24% urea, treat that solution temperature drops to 53～55 ℃, add again 20～22% water and dilute, stir 30～40 minutes until solution temperature is down to normal temperature.
The present invention compared with prior art has following beneficial effect: do not contain halogen family element, antimony or formaldehyde in (1) fire retardant prescription of the present invention, and other heavy metals, greatly reduce the infringement to human body; (2) fire retardant of the present invention is water-soluble, and it is simple to add technique, can spray by soaking, and pads method textiles is carried out flame-proof treatment; (2) fire retardant of the present invention can obtain uniform Painting effect and anti-immersion flame retardant effect on fabric, and is soft, ventilative.
The specific embodiment
Understanding for ease of technical solution of the present invention, be introduced below in conjunction with concrete embodiment, in stirred tank, add the water that accounts for gross mass 20%, the phosphoric acid of slow adding 28%, heating reactor to 65 ℃, the magnesium hydroxide of adding 6%, stirred 15 minutes, slowly add 24% urea, treat that solution temperature drops to 53 ℃, add again 22% water and dilute, stir 30 minutes until solution temperature is down to normal temperature, it is 85% PHOSPHORIC ACID TECH.GRADE that above-mentioned phosphoric acid adopts concentration, and magnesium hydroxide is the technical grade powder, and purity is 99.5%.
The embodiment of another preparation process and prescription is: add the water that accounts for gross mass 22% in stirred tank, slowly add 30% phosphoric acid, heating reactor to 65 ℃ adds 4% magnesium hydroxide, stirred 10 minutes, slowly add 22% urea, treat that solution temperature drops to 53 ℃, add again 22% water and dilute, stir 40 minutes until solution temperature is down to normal temperature, it is 85% PHOSPHORIC ACID TECH.GRADE that above-mentioned phosphoric acid adopts concentration, and magnesium hydroxide is the technical grade powder, and purity is 99.5%.
The above; be better case study on implementation of the present invention; be not that the present invention is imposed any restrictions, every any simple modification, change and equivalent structure of above embodiment being done according to the technology of the present invention essence changes, and all still belongs in the protection domain of technical solution of the present invention.
