Problems solved by technology

At present, flame retardant finishing agents are mostly halogen and phosphorus. Halogen flame retardants will produce irritating and toxic gases such as HCl and HBr during combustion, which limits their scope of use. Traditional phosphorus flame retardant finishing There are also defects such as the fabric feels hard after finishing, and the surface of the fabric is easy to yellow.

Embodiment 1

[0045] Example 1: The preparation of a precursor formed by reacting polyetheramine (molecular weight: 2000) with IPTES.

[0046] At room temperature, weigh 50 grams of polyetheramine into a three-necked flask, and add 11.15 grams of IPTES dropwise at a certain molar ratio (polyetheramine:IPTES=1.02:2), and heat up to 80 °C, the reaction was continued for 1 hour, and the reaction temperature was lowered to room temperature to obtain a precursor.

Embodiment 2

[0047] Example 2: Preparation of polyetheramine modified γ-isocyanate propyltriethoxysilane (IPTES) hydrolyzate.

[0048] Add 69 grams of the polyetheramine modified γ-isocyanate propyltriethoxysilane (IPTES) precursor in the three-necked flask in Example 1, and slowly add a total of 112 grams of ethanol and 28 grams of water under constant stirring at room temperature. Mix the solution, react for 2 hours, and stand still for 10 hours to obtain a stable polyetheramine-modified γ-isocyanate propyltriethoxysilane (IPTES) hydrolyzate.

Embodiment 3

[0049] Embodiment 3: The preparation of the precursor generated by the reaction of phosphate ester and IPTES.

[0050] At room temperature, weigh 89.5 grams of phosphoric acid ester and place it in a three-necked flask, and add 111.5 grams of IPTES dropwise in a certain molar ratio (phosphoric acid ester: IPTES=1.02:2) to the three-necked flask, and heat up to 80°C. The reaction was continued for 1 hour, and the reaction temperature was lowered to room temperature to obtain a precursor.

Abstract

The invention discloses a sol-type flame retardant, a preparation method and an application thereof. The flame retardant comprises a chemical mixture of diamionalkkoxy modified Gama-Isocyanatopropyltrimethoxysilane hydrolysate and phosphoric acid ester modified Gama-Isocyanatopropyltrimethoxysilane hydrolysate, with the proportion of 1:0.5-3.5; the flame retardant also comprises an alcohol-water mixed liquor; the alcohol-water mixed liquor is the mixed solution of ethanol and water with the weight proportion of 0.5-1.5:1; and the weight proportion of the chemical mixture and the alcohol-watermixed liquor is 0.02-0.15:1. In the invention, the product can effectively improve the hand-feeling after neatening the textile, reinforce the durability of flame-retarding performance of the textileand improve the water-washing firmness of the textile.

Description

technical field [0001] The present invention relates to a kind of sol-type flame retardant and its preparation method and application, more particularly, relates to using polyether amine to modify γ-isocyanate propyl triethoxysilane (IPTES) precursor and its hydrolyzate and phosphoric acid ester A modified γ-isocyanate propyltriethoxysilane (IPTES) precursor and its hydrolyzate, and a sol-type flame retardant formed from the blend product of the two hydrolyzates, as well as its preparation and application methods. Background technique [0002] Curtains play an important role in people's home life. While regulating indoor light and temperature, curtains as a high-density organizational structure can also block part of the noise and achieve ideal indoor shading. This function can meet Consumers are protected from ultraviolet radiation and strengthened private space, and are welcomed by consumers. [0003] In order to obtain high-density shading fabric products, in addition to...
