Problems solved by technology

After using the transition blowing agent HCFC-141b instead of CFC-11 in the market, it still has the depletion effect on the ozone layer
The combined polyether of the cyclopentane system and the products produced after use are flammable, which makes the safety hazard in the use process too great

Embodiment 1

[0013] The preparation of embodiment 1 silicone surfactant

[0014] In a 500ml four-neck flask with a fixed device, a constant temperature function, mechanical stirring, a thermocouple and nitrogen gas, add 250g of polyoxyethylene ether (called polyoxyethylene ether) with an average molecular weight of 750 methyl-terminated starting from allyl alcohol. Polyether A), this polyether A contains the oxirane group that mol percentage is 75% and the propylene oxide group that mol percentage is 25%; Add 50g allylbenzene, mix and stir 5 minutes at normal temperature, then 150g Low hydrogen polysiloxane (referred to as MD 40 D' 12 M) Add it into a four-necked flask, start stirring, heat to 75°C with a heating mantle, stir for 5 minutes, add 20ppm of Pt chloroplatinic acid ethanol solution, and react for 4 hours to obtain a clear and transparent light yellow liquid, which is organic Silicone copolymer surfactant.

Embodiment 2

[0015] The preparation of embodiment 2 silicone surfactants

[0016] In a 500ml four-neck flask with a fixed device, constant temperature function, mechanical stirring, thermocouple and nitrogen gas, add 240g of polyoxyethylene ether (called polyoxyethylene ether) with an average molecular weight of 500 methyl-terminated starting from allyl alcohol (called Polyether B), this polyether B contains the oxirane group that the molar percentage is 60% and the propylene oxide group that the molar percentage is 40%; Add 60g2,4-diphenyl-4-methyl-1- Amylene, mixed and stirred at room temperature for 5 minutes, and then 140g of low-hydrogen polysiloxane (abbreviated as MD 40 D' 12 M) Add it into a four-necked flask, start stirring, heat to 75°C with a heating mantle, stir for 5 minutes, add 20ppm of Pt chloroplatinic acid ethanol solution, and react for 4 hours to obtain a clear and transparent light yellow liquid, which is organic Silicone copolymer surfactant.

Embodiment 3

[0017] The preparation of embodiment 3 silicone surfactants

[0018] In a 500ml four-neck flask with a fixed device, constant temperature function, mechanical stirring, thermocouple and nitrogen gas, add 300g of polyoxyethylene ether (called polyoxyethylene ether with an average molecular weight of 1250) of methyl-terminated starting from allyl alcohol. Polyether C), this polyether C contains the oxirane group that is 60% by mole percent and the propylene oxide group that is 40% by mole percent; Add 100g allyltriphenylphosphine bromide, mix and stir at room temperature for 5 Minutes, then 100g of low hydrogen-containing polysiloxane (referred to as MD 40 D' 12 M) Add it into a four-necked flask, start stirring, heat to 75°C with a heating mantle, stir for 5 minutes, add 20ppm of Pt chloroplatinic acid ethanol solution, and react for 4 hours to obtain a clear and transparent light yellow liquid, which is organic Silicone copolymer surfactant.

Abstract

The invention provides a flame-retardant organic silicon surfactant and application thereof to preparation of flame-retardant polyurethane rigid foam. A general formula of the flame-retardant organicsilicon surfactant is MDxD'yM, wherein M is selected from any one of (CH3)3SiO1 / 2 and (CH3)2RSiO1 / 2; D refers to (CH3)3SiO2 / 2; D' refers to (CH3)2(R)SiO2 / 2; x+y refers to 5-50, y refers to 3-13; R isselected from at least one of unblocked polyether portions and at least one radicals containing benzene rings. The organic silicon surfactant is capable of improving flame retardation of polyurethanerigid foam; especially in application to solar water heaters, high flame retardation of polyurethane foam plastic can be achieved without adding of flame retardants. In addition, the flame-retardant organic silicon surfactant has advantages of high fluidity and high storage stability in combined materials.

Description

technical field [0001] The invention relates to the field of polymer chemical industry, in particular to surfactants, in particular to a flame-retardant organic silicon surfactant and its application. Background technique [0002] New energy is one of the five most decisive technological fields in the world economic development in the 21st century. Solar energy is a clean, efficient and inexhaustible new energy source. In the construction industry, polyurethane insulation panels provide excellent insulation. In practice, governments of various countries regard the utilization of solar energy resources and polyurethane insulation boards as an important part of sustainable development strategies. Due to the advantages of heat insulation, low density and high specific strength, polyurethane rigid foam is widely used in the solar energy industry and building insulation. After using the transition blowing agent HCFC-141b instead of CFC-11 in the market, it still has depletion ...
