Problems solved by technology

[0003] As people's awareness of safety and environmental protection gradually increases, higher and higher requirements are put forward for the odor and low toxicity of polyurethane foam toys. The traditional high volatility, high odor, A material containing HCFC-141B physical blowing agent and TDI type B material with high vapor pressure (1.33Pa, 20°C) can no longer meet the requirements

Embodiment 1

[0031] A component is:

[0032]

[0033] Group B is divided into:

[0034]

[0035] Component A: Put the weighed FA-703 and POP3630 into the reaction kettle and stir, then add the weighed DEOA, DEG, L-3415, MP601, MP602, H 2 O. After stirring and mixing at room temperature for 1 hour, take a sample for inspection, meet the process parameters, and produce satisfactory foam, that is, the qualified product of component A is obtained.

[0036] Component B: Add EP3600 and Yukol 8331 to the reaction kettle at room temperature, stir and heat up to 90°C-100°C, dehydrate and degas under vacuum (-0.098MPa) for 2-3 hours, when the temperature drops to 30°C, add pure MDI and Liquefy MDI, react for 2-3 hours when the temperature is raised to 80-85°C, and detect that the NCO% content reaches the set value (25.3%), then add crude MDI, stir and cool down to 10-40°C.

[0037] When in use, the components A and B are mixed according to the weight ratio of A:B=100:34 and injected into the...

Embodiment 2

[0039] A component is:

[0040]

[0041] Group B is divided into:

[0042]

[0043]

[0044] Component A: Put the weighed EP3600Y and POP40 into the reaction kettle and stir, then add the weighed DEOA, DEG, L-3415, EF600, EF700, H 2 O. After stirring and mixing at room temperature for 1 hour, take it out for inspection, meet the process parameters, and produce satisfactory foam, that is, the qualified product of component A.

[0045] Component B: Add FA703 and Yukol 8331 into the reaction kettle at room temperature, stir and heat up to 90°C-100°C, dehydrate and degas under vacuum for 2-3 hours, when the temperature drops to 30°C, add pure MDI and liquefied MDI, and heat up to React at 80-85°C for 2-3 hours. After the detection reaches the set NCO% content (26.1%), then add crude MDI, stir and cool down to 10-40°C.

[0046] When in use, the components A and B are mixed according to the weight ratio of A:B=100:50 and injected into the mold to obtain a polyurethane foa...

Embodiment 3

[0048] A component is:

[0049]

[0050] Group B is divided into:

[0051]

[0052] Component A: Put the EP3600Y and POP3630 based on the formula into the reaction kettle and stir, then add the weighed DEOA, DEG, L-3415, MP601, MP602, H2O respectively, stir and mix at room temperature for 1 hour, then take it out and carry out Inspection, meet the process parameters, and produce satisfactory foam, that is, the qualified product of component A.

[0053] Component B: Add FA703 and Yukol 8331 into the reaction kettle at room temperature, stir at 90°C-100°C, dehydrate and degas under vacuum for 2-3 hours, add pure MDI and MDI-50 when the temperature drops to 30°C, and heat up to 80-85°C, react for 2-3 hours, and detect that the set NCO% content is reached, then add crude MDI, stir and cool down to 10-40°C.

[0054] When in use, the components A and B are mixed according to the weight ratio of A:B=100:42 and injected into the mold to obtain a polyurethane foam toy.

Abstract

An environment-friendly polyurethane composite material for foam toys and a preparation method thereof belong to the polyurethane field. The composite material is composed of a component A and a component B, wherein the component A comprises polyether polyol, polymer polyol, a chain extender, a cross-linking agent, a foam stabilizer, a foaming agent and a catalyst; the component B comprises polyether polyol, MDI, modified MDI and an open cell agent. When in use, the component A and component B are mixed according to the weight ratio of A: B=100: 30-50, and the mixture is injected into a die so as to prepare a polyurethane foam toy. The composite material contains no toxic substances or environmental pollutants such as TDI, a heavy metal catalyst, 141B and the like, has low volatility and is environmental friendly; products prepared by the use of the composite material is safe and nontoxic, has good elasticity, good hand feeling and excellent performance; the component A and component B react at room temperature and the die doesn't need heating, thus saving energy and reducing heating equipment.

Description

technical field [0001] The invention belongs to the field of polyurethane, in particular to an environment-friendly polyurethane composite material for foam toys and a preparation method thereof. Background technique [0002] Since the reform and opening up, the toy industry has developed rapidly and the variety has continued to increase. Among them, polyurethane foam toys have won people's love for their excellent feel, beautiful appearance, high resilience and safety. The types of polyurethane foam toys include polyurethane foam solid balls, polyurethane foam teddy bears, polyurethane foam toy figure models, etc., which can be made into various shapes according to different molds. [0003] As people's awareness of safety and environmental protection gradually increases, higher and higher requirements are put forward for the odor and low toxicity of polyurethane foam toys. The traditional high volatility, high odor, A material containing HCFC-141B physical blowing agent and...
