In described component A, polyisocyanates is TDI.
In described component A, catalyzer is CUCAT-HA, and catalyzer CUCAT-HA is the elastomerics special-purpose catalyst that Guangzhou You Run company produces, and has the advantages that to press down water, reduction of speed, environmental protection, improves the operability of technique.
In described B component, polyether glycol is DDL-3000D; Polyether glycol DDL-3000D (molecular weight is 3000, and functionality is 2) believes that federal Chemical Co., Ltd. produces for Zibo moral, and it is less that this kind of polyether glycol obtains product hardness, has the advantages that to prevent scratching fingers.
In described B component, vulcanizing agent is MOCA.
The preparation method of urethane Safety far blade of the present invention, step is as follows:
(1) preparation of component A: polyether glycol is warming up to 80-120 DEG C of vacuum hydro-extraction 1-3 hour, be cooled to less than 50 DEG C and add polyisocyanates, be warming up to 80-85 DEG C of reaction after 2-3 hour, obtain performed polymer, be cooled to less than 50 DEG C to add catalyzer and stir, seal for subsequent use;
(2) preparation of B component: polyether glycol, vulcanizing agent and mill base are mixed and heated to 80-120 DEG C and stir 10-30 minute;
(3) after A, B component being heated to 80-120 DEG C respectively, mixing and stirring, pours mould into, heated die 2-3 hour, and after the demoulding, namely 110-130 DEG C obtain finished product in sulfuration 2-4 hour.
The NCO% of the performed polymer described in step (1) is 7-10%.
Hardness of the present invention is moderate, toughness is better, do not have sharp section, when finger is stretched into fan by children accidentally, blade can produce certain deformation thus the risk of cutting finger dropped to minimum and avoids the possibility bringing the diseases such as tetanus when irony blade scratches.
The present invention compared with prior art, has following beneficial effect:
(1) the urethane Safety far blade that obtains of the present invention, if with children's finger contact when it rotates, comparatively soft due to it and characteristic without sharp section greatly reduces the possibility scratching and even disable, and avoid the possibility bringing the diseases such as tetanus when irony blade scratches.
(2) the product once shaped of using the present invention to prepare, greatly reduces labour cost.
(3) preparation method of the present invention is simple and easy to implement.
