Embodiment 1

[0007] Negative ion releasing flexible foam: polyether polyol (100)

[0008] TDI (47)

[0009] Negative Ion Additives (4)

[0010] h 2 O (3.5)

[0011] Stannous octoate (0.6)

[0012] Triethylenediamine (0.4)

[0013] Silicone oil (1.5)

[0014] Process: Polyether polyol and TDI are vacuum-dried at 40°C for 1 hour respectively; other raw materials are preheated at 40°C. Accurately weigh the dried polyether polyol according to the formula and pour it into the reactor, add triethylenediamine, stannous octoate, water, silicone oil and negative ion additives, fully disperse it with an electric mixer, and then add the dried isocyanate , high-speed stirring until the reaction begins (a small amount of bubbles emerge), pour into the mold, quickly close the mold, the chemical reaction proceeds quickly, and after the reaction is completed, it i...

Embodiment 2

[0017] Negative ion releasing rigid foam: polyether polyol (100)

[0018] PAPI (135)

[0019] H2O (0.1)

[0020] Stannous octoate (0.4)

[0021] Triethanolamine (0.6)

[0022] Silicone Oil (1.0)

[0023] Negative Ion Additives (4)

[0024] Process: Polyether polyol and PAPI were vacuum-dried at 40°C for 1 hour respectively; anion additives were dried in an electric thermostat oven at 100°C for 1 hour; other raw materials were preheated at 40°C. Accurately weigh the dried polyol and pour it into the reactor, add triethanolamine and organotin, add negative ion additive after preliminary dispersion, fully disperse it with an electric mixer, add dried isocyanate, stir at high speed until the reaction starts (A small amount of air bubbles come out), pour into the mold, and the chemical reaction of the mold is quickly closed. After the...

Embodiment 3

[0027] Anion-Releasing Polyurethane Elastomers: Polyether Polyols (100)

[0028] TDI (18)

[0029] Ethylene glycol (3.5)

[0030] Silicone oil (1.0)

[0031] Negative Ion Additives (4)

[0032] Process: First, weigh polyether polyol and negative ion additives, and mechanically stir and vacuum defoam for 1 hour under the conditions of 130°C and vacuum degree of 5×133Pa~10×133Pa until the mixture is uniform and no bubbles emerge. Cool down to 85°C, add accurately weighed TDI, and continue to mechanically stir for 1 hour under the condition of a vacuum degree of 5×133Pa~10×133Pa to obtain a prepolymer. Weigh an appropriate amount of ethylene glycol, add it to the prepolymer, stir rapidly at 85°C for 5 minutes, then pour it into the mold, and then place the mold in an oven at 110°C for curing and aging. After 14 hours, the finished product can be obtained by demoulding.

Abstract

The invention adopts nano-silica and a series of superfine powder body which can release anion and creates Anion series anion additive using a doping and blending method, which can be added to the polymer materials such as polyurethane fibers, plastics, dopes and additives, etc, and the modified polyurethane composite provided with releasing anion functions is successfully produced. The invention can be applied in the fields of Chemistry and Chemical industry, the spinning, the rag trade, the automotive trim, the health and the environment protecting, the nano-silica and the superfine powder which can release anions have a good dispersivity in the composite and no technical defaults exist in the processing process.

Description

Technical field: [0001] The invention belongs to the fields of materials, chemical engineering, textiles, clothing, shoemaking, automobile interior decoration, health, environmental protection and the like. Background technique: [0002] With the improvement of human civilization and production activities, especially the increasing degree of industrialization, the pollution is becoming more and more serious, especially people desire an elegant, healthy and environmentally friendly environment, so various environmentally friendly materials and healthy functional materials have emerged as the times require. Negative ions have been paid more and more attention by scientists to improve people's living environment. Negative air ions are called "air vitamins" or "longevity", and the number of negative ions to maintain people's health is: 1000-2000 / cm 3 . People who live and work in modern air-conditioned buildings for a long time often feel bored, drowsy, fatigue, nausea, headac...
