Abstract

The invention provides neutral flame retardant liquid. The neutral flame retardant liquid comprises, by weight percent, 30%-50% of water, 15%-30% of phosphoric acid, 1%-5% of multidirectionally-complexed central atom zinc, 2%-10% of phosphorylated castor oil, and 5%-52% of ammonium hydrogen phosphate. The neutral flame retardant liquid is colorless and odorless and is neutral with pH of 7.

Description

A kind of neutral fire resistant fluid

Technical field

The present invention relates to a kind of neutral fire resistant fluid, belong to chemical field.

Background technology

At present, existing on the market each based flame retardant, fire resistant fluid, the most acidity of its moity is strong excessively; When using this type of fire resistant fluid, be easy to article are produced corrosive damage, shortened the work-ing life of article; In a kind of new type fireproof and fire-retardant liquid of patent documentation (95111015.2) fire resistant fluid that is dissolved in the water and processes with phosphoric acid, ammoniacal liquor, carboxamide, ammonium salt, ether of cellulose or compound cellulose ether, borate, benzoate, saturated fatty hydrochlorate is provided at home; The fire resistant fluid that mixes with malonamide nitrile and water that a kind of fire resistant fluid (201110278573.7) is mentioned; The fire resistant fluid of being given an example, its fundamental characteristics, acidity is strong excessively, and the substruction of fragile article is destroyed the article life cycle.

Summary of the invention

Strong excessively in order to overcome existing its acidity of fire resistant fluid, the easy damaged article structure the invention provides a kind of neutral fire resistant fluid, and this fire resistant fluid not only can well play fire-retardant effect, has also solved the strong excessively problem of its acidity simultaneously.

The technical solution adopted for the present invention to solve the technical problems is: the blender that in the moity of fire resistant fluid, adds alkalescence; The acidity of original fire resistant fluid is neutralized; Its concrete moity is by weight percentage: water 30%-50%, phosphatase 11 5%-30%, multidirectional complexing central atom zinc 1%-5%, phosphorylation Viscotrol C 2%-10%, ammonium hydrogen phosphate 5%-52%; And said prescription put in order the flask of 500ml; The cooling that is no less than 20 minutes is evenly stirred, and prepared neutral fire resistant fluid, its pH value are 7; This neutrality fire resistant fluid is colourless, tasteless.

The invention has the beneficial effects as follows: make original acid fire resistant fluid become neutrality, avoided when using fire resistant fluid, article being corroded, ensured its work-ing life.

Description of drawings

Below in conjunction with accompanying drawing and embodiment the present invention is further specified.

Fig. 1 is the concrete formula rate chart of a kind of neutral fire resistant fluid of the present invention.
