Embodiment 1-5 and comparative example 1-2
[0041] Example 1-5 and Comparative Example 1-2 Preparation of Fiber Matrix Containing Flexible Polymer Insulator Grafts
[0042] The fibrous matrix containing flexible polymer insulator grafts of Examples 1-5 of the present invention and Comparative Examples 1-2 includes the following preparation raw materials in parts by weight, as shown in the following table:
[0043] group
Embodiment 1-3
[0044] Embodiment 1-3 The preparation of the fibrous matrix containing the flexible polymer insulator graft is:
[0045] (1) Add the seaweed fiber into the water several times in small amounts under continuous stirring to make a solution with a mass fraction of 10%, then add polyethylene glycol, and stir at a low speed for 30 minutes;
[0046] (2) add polytrimethylene carbonate and succinic anhydride in the material of step (1) gained, mix, place in the airtight reactor behind logical high-purity nitrogen deoxygenation, in 60 Carry out radiation grafting treatment under Co-γ rays, the treatment time is 12min, and the radiation dose is 10kGy, then take it out and place it for 3h, and dry it to obtain seaweed fibers grafted with flexible polymers;
[0047] (3) the seaweed fiber of the grafted flexible polymer that step (2) obtains is through opening, carding, laying net, prewetting, spunlace, oven dry preparation thickness be the non-woven fabric base material that thickness is ...
