5Be methylene group.
Compared with prior art; The present invention is owing to added water-retaining agent, and the water-retaining agent of utilization can absorb quantitative moisture, and willing characteristics; Acetal or ketal and the trace or and the trace the reacted product of water be corresponding alcohol, aldehydes or ketones; And alcohol, the aldehydes or ketones of the trace that generates can be used as organism is dissolved in becomes tackiness agent in the tackiness agent a part, thereby have increased the bounding force of tackiness agent, and can people, mobile phone and notebook computer and environment not caused damage; Can effectively stop the steam of trace in the environment to get into inside battery from the battery case junction, thereby can greatly prolong the work-ing life of the battery of mobile phone or notebook computer.
The present invention will solve another technical problem: provide the simple battery of a kind of ME to stick with glue the preparation method of agent, it may further comprise the steps:
At first in container, add propenoate 84%～95%, Acrylic Acid Monomer 4%～15% and chain initiator 1 ‰～5 ‰, and mix; Postheating to 75～85 ℃, and, drip 1 of 40～180g behind reaction 4.5～5.5h to constantly stirring in the container, the 6-glycol diacrylate continues to stir 1.5～2.5h; Then stop heating, continue stirring and be cooled to room temperature; Add water-retaining agent 0.1%～5% at last, stir, process non-setting adhesive and get final product.
Described propenoate is Isooctyl acrylate monomer, methyl acrylate, Bing Xisuandingzhi or NSC 20949.
Described water-retaining agent is acetal or ketal.
The structural formula of described acetal or ketal is:
R
1, R
2Group is for being Wasserstoffatoms, methyl, ethyl, propyl group, butyl or isopropyl group; R
3, R
4Group is methyl, ethyl, propyl group, sec.-propyl or butyl group; R
5Be methylene group.
Compared with prior art, the present invention does not have special devices owing to do not have special preparation condition in the whole process yet, and preparation technology is simpler, and efficient is higher; Simultaneously in the preparation process, dripped 1; The 6-glycol diacrylate as water-retaining agent and water catalyst for reaction, and just adds water-retaining agent after being cooled to room temperature; So water-retaining agent can not lose efficacy because of the water that polyreaction produces in advance; Guarantee product when bonding battery, the water-retaining agent in the product still can absorb moisture, thereby guarantees the stability in use of product.
