Example Embodiment

[0031] Example 1

[0032] 400g DOPO, 50g sodium lignosulfonate and 350g water were added to the colloid mill and ground for 8 hours, 200g of 5% carboxymethyl cellulose was added, and the grinding was continued for 20 minutes to obtain a yellow-brown flame-retardant dispersion system with a particle size of 1.3 μm.

Example Embodiment

[0033] Example 2

[0034] 200g DOPO, 60g dispersant MF and 540g water were added to the colloid mill and ground for 4 hours, 200g 5% hydroxyethyl cellulose was added, and the grinding was continued for 10 minutes to obtain a yellow-brown flame-retardant dispersion system with a particle diameter of 1.6 μm.

Example Embodiment

[0035] Example 3

[0036] 200g of DOPO, 60g of dispersant NNO and 540g of water were added to the colloid mill to grind for 12 hours, 200g of 5% methylcellulose was added, and the grinding was continued for 30 minutes to obtain a white flame-retardant dispersion system with a particle size of 1.1 μm.

Abstract

The present invention relates to a phosphorus-containing flame retardant system polyester after-treatment and preparation and application thereof. The system includes, by weight, 10-60% of a phosphorus-containing flame retardant DOPO, 1-10% of a dispersant, 0.1-3% of a dispersion stabilizer and the balance of water. The phosphorus-containing flame retardant system is obtained by a grinding method, and is used for after-treatment. The phosphorus-containing flame retardant system prepared by the present invention is applied to polyester fabric flame retardant finishing in a way of after-treatment; compared to the of flame retardant complex technique and monomer selection difficulty in copolymerization flame retardation and flame retardant selection difficulty and great impact on the properties of the fibers in blending flame retardation, and the system has the advantages of flexible and convenient processing, simple process, and no effect on the fabric mechanical properties.

Description

technical field [0001] The invention belongs to the field of flame retardant system and its preparation and application, in particular to a phosphorus-containing flame retardant system for polyester finishing and its preparation and application. Background technique [0002] Polyester has a wide range of uses and can be used to make decorative fabrics, carpet fluff, fire suits or fire hoses, etc. Most of them require flame retardant properties. Halogen-containing flame retardants are a class of effective flame-retardant finishing agents for polyester, especially bromine-containing flame retardants, such as decabromodiphenyl ether and hexabromocyclododecane. Since 1986, when a Swiss research institution discovered the Dioxin problem of halogenated flame retardants, these flame retardants have been banned continuously. Phosphorus-containing flame retardants are gradually replacing halogen-containing flame retardants in polyester. The commercialized phosphorus-containing flame...
