Problems solved by technology

[0004] CN101993559A uses a large amount of magnesium hydroxide and calcium carbonate as filling flame retardants, and uses high-pressure low-density polyethylene, EPDM rubber and random polypropylene as base materials. The green and environmentally friendly flame-retardant carpet backing material is melted in a strip oven and finally pressed on a flat vulcanizing machine. The preparation process is complicated and can only be used as a backing material for general carpet tiles.
[0005] CN1301279A is mainly composed of polyurethane dispersant, flame retardant ammonium polyphosphate and melamine, carbon forming agent pentaerythritol and polysaccharide, etc., supplemented by defoamer and water, grinded and mixed at high speed, and then coated on the carpet backing to dry The preparation process is complex, and the flame retardant component is unevenly dispersed in water and other media, which makes it difficult and uniform for the flame retardant to soak on the carpet backing fiber

Embodiment 1

[0025] Example 1: Add 15.0 parts of water and 1.25 parts of hydroxyethylene diphosphonic acid to a reactor with a jacketed coil and stirring, and after constant stirring to disperse the hydroxyethylene diphosphonic acid into a homogeneous system, use Slowly add 1.0 part of diethylene triamine to the constant pressure dropping funnel, and continuously pour cooling water into the jacketed coil to control the temperature of the whole reaction solution at 30℃~50℃. After the addition of diethylene triamine is completed, After reacting for 0.5 hours under normal pressure, a colorless, odorless, halogen-free environmentally friendly flame retardant is obtained upon discharge.

Embodiment 2

[0026] Example 2: Add 15.0 parts of water and 5.0 parts of hydroxyethylene diphosphonic acid to a reactor with a jacketed coil and stirring. After stirring continuously to disperse the hydroxyethylene diphosphonic acid into a homogeneous system, use The constant pressure dropping funnel was slowly added 4.0 parts of diethylene triamine, and cooling water was continuously introduced into the jacket coil to control the temperature of the whole reaction solution at 30 ℃ ~ 50 ℃, and after the addition of diethylene triamine was completed, It reacts for 0.5 hours under normal pressure, and the halogen-free environmentally friendly flame retardant is obtained after discharge.

Embodiment 3

[0027] Example 3: Add 15.0 parts of water and 10.0 parts of hydroxyethylene diphosphonic acid to a reactor with a jacketed coil and stirring. After stirring continuously to disperse the hydroxyethylene diphosphonic acid into a homogeneous system, use Slowly add 8.0 parts of diethylene triamine to the constant pressure dropping funnel, and continuously pass cooling water into the jacketed coil to control the temperature of the reaction solution at 30°C to 50°C. After the drop of diethylene triamine is completed, It reacts for 0.5 hours under normal pressure, and the halogen-free environmentally friendly flame retardant is obtained after discharge.

Abstract

The invention discloses preparation of a halogen-free environment-friendly fire retardant for a signature cotton back-lining nylon carpet and a formula of a coating liquid. An organic phosphonic acid, an organic amine and a solvent which are in proper proportion are selected to be prepared into the halogen-free environment-friendly fire retardant. The halogen-free environment-friendly fire retardant, a non-formaldehyde cotton linen fabric cross-linking agent and water are prepared into the coating liquid. The fire-retardant performance of a fire-retardant nylon carpet manufactured by nylon yarns prepared from the fire retardant exceeds the Dfl level (CHF is greater than or equal to 3.0 kW / m<2>) of the inflammability of a flooring material specified by GB20286-2006, and reaches the B1 level (CHF greater than or equal to 4.5 kW / m<2>) to satisfy a higher requirement. In addition, the toxicity of generated smoke exceeds the t1 level. As a result, the fire retardant disclosed by the invention meets the environment-friendly requirement.

Description

Technical field [0001] The invention relates to the preparation of a halogen-free environmentally friendly flame retardant for cotton and linen backing nylon carpets and a coating liquid formula Background technique [0002] The carpet tiles and Wilton carpets used in public places are composed of surface fabrics and backing fabrics. Commonly used materials for surface fabrics include polypropylene fiber, nylon fiber (ie nylon), polyester fiber, etc.; backing materials are commonly used There are: hemp, PVC, EVA, SBR, etc. Among them, nylon carpets are generally used in public places such as airplanes and high-end hotels. With the continuous improvement of people’s living standards, people’s requirements for the environment have become more and more stringent: flame-retardant products require halogen-free, low-smoke and environmentally friendly non-corrosion during combustion, especially GB20286-2006 (flame retardant products and components in public places) Requirements and ma...
