Embodiment 1
[0037] see Figure 1-3 , the polyurethane composition that the present invention is used for imitation wood spraying all-water foaming system, polyurethane composition is prepared by the component of following parts by weight:
[0038] Polyether: 85 parts; Polyester: 15 parts; Crosslinking agent: 3-5 parts; Catalyst: 1-5 parts; Foam stabilizer: 2-5 parts; Water: 1-1.5 parts.
[0039] The present invention also provides the above-mentioned preparation method for the polyurethane composition of imitation wood spraying all-water foaming system, comprises the following steps:
[0040] S1. Raw material configuration: according to the set weight ratio, polyether and polyester are placed in the equipment for configuration;
[0041] S2. Heat exchange and grinding: Pump the prepared slurry to the grinding equipment for grinding. During the slurry pumping process, heat exchange is performed through the heat exchange equipment, and the viscosity is reduced by increasing the temperature ...
Embodiment 2
[0060] The polyurethane composition, preparation method and equipment for wood-like spraying all-water foaming system provided in this embodiment are basically the same as in Example 1, except that:
[0061] In this embodiment, the polyurethane composition used for imitation wood spraying all-water foaming system is specifically prepared from the following components by weight:
[0062] Polyether: 60 parts; polyester: 15 parts; crosslinking agent: 3-5 parts; catalyst: 3-5 parts; foam regulator: 5-7 parts; water: 5-10 parts.
Embodiment 3
[0064] The polyurethane composition, preparation method and equipment for imitation wood spraying all-water foaming system provided by this embodiment are basically the same as embodiment 1 and embodiment 2, and its difference is:
[0065] Polyether: 60 parts; Polyester: 15 parts; Crosslinking agent: 1-3 parts; Catalyst: 2-4 parts; Foam stabilizer: 3-6 parts; Water: 4-8 parts.
