Embodiment 3

[0052] Embodiment 3 prepares reticulated polyurethane flexible foam:

[0053] Adopt above-mentioned embodiment 1, embodiment 2, select for use to add the prescription of activating agent cell opener as comparative example 1, implement the reticular polyurethane flexible foam that 2 prepares, select foam density as 24kg / m 3 The formula, the result is as following table 1:

[0054] According to the formula in Table 1, weigh the required polyether polyol V-3010, deionized water, amine catalyst Dabco*33LV, silicone surfactant BL-580NA, and dichloromethane. Then the mixture was stirred at 1500 revolutions per minute for 2 hours, and then the mixture was stored in a storage tank with a temperature-controlled water bath, and slowly stirred until the temperature of the polyether composite material was controlled at 21 degrees.

[0055] According to the formula in Table 1, in a container with a capacity of about 100L, the polyether combination material, activator cell opener, and stan...

Abstract

The invention provides an active openings agent. The active openings agent is composed of a compound generated through reaction of dihydric alcohol of oxyalkylene ether with two or more primary hydroxyl group structures or polyhydric alcohols and first acid anhydride, at least one amine compounds, at least one acid or second acid anhydride, a compound containing phosphorus and simethicone. The invention further provides a preparation method for the active openings agent. The invention provides an areticulated urethane foam material which is composed of polyether polyol, deionized water, dichloromethane, stannous octoate, amine catalyst, TDI80 / 20, organosilicon surfactant and an openings agent. The further provides a preparation method for the reticulated urethane foam material. The novel active openings agent is used for preparing the reticulated urethane flexible foam material, the opening performance of the foam material can be improved, the operation tolerance level of the technology is improved, the foam material is prevented from contracting, and safety is high.

Description

technical field [0001] The invention belongs to the field of chemical industry and relates to an active cell opener, a reticular polyurethane foam and a preparation method thereof. Background technique [0002] Flexible polyurethane foam (commonly known as polyurethane foam) is usually made of polyether polyol or polyester polyol, water, amine catalyst, silicone surfactant, tin catalyst, physical blowing agent, other additives and isocyanate Mixing under high-speed stirring, the polyol, water and isocyanate react quickly under the action of the catalyst to form a foam with a network structure. Stop expanding, and finally the gas inside the foam volatilizes from the foam, and the foam reaches the maximum volume. After the gas volatilizes, the foam slightly falls back, and it is basically formed after five minutes. [0003] Reticulated polyurethane flexible foam belongs to a new type of functional foam in flexible polyurethane foam, also known as filter cotton, mesh sponge, b...
