The halogen-free flame retardant liquid provided by the invention solves the problems of low thermal stability, poor environmental friendliness, large influence on products, poor water solubility and the like of a flame retardant in the prior art, has the advantage of small dosage, and has potential economic value.
Description
The application is a divisional application of application No. 202010454434.4, 26 months in 2020, and the application name is halogen-free flame retardant liquid and application thereof.
Technical Field
The invention relates to a preparation method and application of halogen-free flame retardant liquid.
Background
Most of materials contacted in daily life are combustible substances such as wood products, fibers, cotton, hemp, wool, paper and the like, and most of the materials are not subjected to flame retardant treatment, so that great fire hazards exist, and personal casualties and property loss can be caused once the fire occurs. To prevent fire, various flame retardant products are continuously being developed. At present, halogen-based flame retardants, namely brominated and chlorinated flame retardant products, are widely used, but such flame retardants have great drawbacks: the ultraviolet resistance stability of the flame-retardant base material is reduced, and more smoke, corrosive gas and toxic gas are generated when the flame-retardant base material burns, so that the pollution and harm to the surrounding environment are caused. Based on this, development and research of halogen-free flame retardants are gradually being turned to obtain environmental safety and use safety, and are nontoxic and harmless. From the aspect of morphology, the halogen-free flame retardant comprises solid powder, resin, water emulsion, water base and the like, wherein the water base product has the advantages of convenient use, low cost and easy adhesion, can be sprayed on the surface of the product, can fully absorb the flame retardant liquid through soaking, and has very convenient flame retardant treatment.
The traditional water-based flame-retardant product mainly comprises a foaming type product, which comprises the following three components: 1) An acid source; 2) A carbon source; 3) And (5) an air source. The biggest problems with conventional water-based flame retardants are: most of the substances are not water-soluble, so that dispersing agents and anti-settling agents have to be added, so that the surface of the treated product is opaque, precipitation and crystallization are serious, the surface quality of the product is greatly influenced, and the hygroscopicity of some components is serious, so that the mechanical property of the product is greatly influenced; in addition, some components are not degradable, and bring harm to the ecological environment. Meanwhile, the flame retardant liquid prepared by using the small molecules has poor thermal stability, and the flame retardant can be decomposed and destroyed at a lower temperature. Poor thermal stability, decomposition is destroyed at lower temperatures; the water solubility of the effective components is extremely poor, and a dispersing agent and an anti-settling agent are added for treatment; the hygroscopicity of part of the components is serious, and the mechanical property of the product is greatly influenced; part of the components are not degradable, and bring harm to the ecological environment; the obtained traditional water-based flame-retardant product also has the problems of extremely poor surface transparency and serious crystallization.
Therefore, there is a need to develop a water-soluble flame retardant which has high thermal stability, is environmentally friendly, has little influence on the product and has a small amount of use.
Disclosure of Invention
(one) solving the technical problems
In the prior art, the flame retardant has the defects of low thermal stability, poor environmental friendliness, large influence on products, poor water solubility and the like, and the halogen-free flame retardant liquid provided by the invention is a water-soluble flame retardant with high thermal stability, environmental friendliness, small influence on products and small dosage.
(II) technical scheme
In order to achieve the purposes of low cost, simple method and excellent performance:
in one aspect, the present invention provides the following technical solutions: a halogen-free flame-retardant liquid, which comprises zinc methylethyl hypophosphite and water. Alkyl phosphinates are a kind of dialkyl halogen-free flame retardant, have good thermal stability and flame retardance, and generally, alkyl phosphinates have no water solubility. In the application, when the alkyl hypophosphite is zinc methylethyl hypophosphite, the water-soluble flame retardant prepared from zinc methylethyl hypophosphite has good water solubility, excellent heat stability and flame retardant property, and good smoke suppression property.
The halogen-free flame retardant liquid also comprises an aqueous thickener and/or a water-soluble surfactant.
The halogen-free flame retardant liquid comprises the following components in parts by weight:
0-5 parts of water-based thickener, 0-3 parts of water-soluble surfactant, 2-9 parts of methyl ethyl zinc hypophosphite flame retardant and 100 parts of water.
The term "thickener" is a substance that increases the viscosity of latex, liquids, and can increase the viscosity of a system, maintain a uniform and stable suspension or emulsion, or form a gel, most thickeners having an emulsifying effect. There are many materials that can be used as thickeners, and most commonly used are about 40 kinds of thickeners, and the aqueous thickener is used in the present invention.
Preferably, the aqueous thickener is at least one of xanthan gum, water-soluble polyacrylate and hydroxyethyl cellulose. It will be appreciated that other suitable thickeners than those listed herein can be selected by those skilled in the art as desired and are within the scope of the invention.
The term "surfactant" refers to a substance added in small amounts to cause a significant change in the interfacial state of the solution system. Has immobilized hydrophilic and lipophilic groups, and can be oriented on the surface of the solution. The molecular structure of the surfactant has amphipathy: one end is hydrophilic group, and the other end is hydrophobic group; the hydrophilic group is usually a polar group such as carboxylic acid, sulfonic acid, sulfuric acid, amino or amine group and salts thereof, and hydroxyl group, amide group, ether bond and the like can also be used as the polar hydrophilic group; while hydrophobic groups are often nonpolar hydrocarbon chains, such as hydrocarbon chains of more than 8 carbon atoms.
Preferably, the water-soluble surfactant is at least one of triphenyl phenol polyoxyethylene ether (602 #), dioctyl sodium sulfosuccinate (quick-setting T), adipic acid polyester (W-1640), glycerol stearate (MSD-608), silane coupling agent (KH 550), sodium dodecyl sulfate (K12) and sodium alkyl naphthalene sulfonate (BX). It will be appreciated that other suitable surfactants than those listed herein can be selected by those skilled in the art as desired and are within the scope of the invention.
Preferably, the halogen-free flame retardant liquid further comprises 0-0.2 part of a color fixing agent and 0-1 part of a colorant.
The term "fixing agent" is one of the important auxiliary agents in the printing and dyeing industry, and can be used for improving the color wet-fastness of the dye on the fabric. Insoluble colored materials can be formed on the fabric with the dye, so that the washing fastness and perspiration fastness of the color are improved, and the light fastness of the fabric can be improved in some cases.
In the present invention, preferably, the fixing agent is a water-soluble fixing agent. It should be understood that one skilled in the art can select an appropriate water-soluble fixing agent as desired while remaining within the scope of the present invention.
For the term "colorant," any substance that can cause the substance to appear to the design requiring color is referred to as a colorant. It may be organic or inorganic and may be natural or synthetic.
In the present invention, preferably, the colorant is ink, color paste or pigment. It should be understood that one skilled in the art can select the appropriate colorant as desired and within the scope of the present invention.
Preferably, the halogen-free flame retardant liquid comprises 1.5 parts by weight of xanthan gum, 1 part by weight of glycerol stearate (MSD-608), 5 parts by weight of zinc methylethyl hypophosphite and 100 parts by weight of water.
