Carbon fiber/alkali-activated composite pressure-sensitive material and preparation method thereof
The invention relates to the technical field of conductive concrete, and discloses a carbon fiber/alkali-activated composite pressure-sensitive material, which is prepared from the following raw materials in parts by weight: 10 to 20 parts of sodium hydroxide, 6 to 12 parts of silicon powder, 40 to 80 parts of water, 0.8 to 1.6 parts of dispersing agent, 1 to 2 parts of defoaming agent, 30 to 60 parts of sand material, 1 part of electrode plate, 1 part of carbon fiber, 1 part of protective coating and the like. According to the carbon fiber/alkali-activated composite pressure-sensitive material and the preparation method thereof, the titanium alloy wire mesh is added into the slurry, so that electrode plates are uniformly distributed in the composite pressure-sensitive material subjected to composite molding, the conductivity of the composite pressure-sensitive material is guaranteed, the flowability of conductive concrete is reduced, and a conductive phase is prevented from being agglomerated and clustered; the composite pressure-sensitive material is uniformly heated by using the composite pressure-sensitive material, and the defoaming agent formed by polydimethylsiloxane and dispersed carbon fibers are utilized, so that pores in the conductive concrete are reduced, the stability of reaction of free water and various ions in the later period is guaranteed, and the service life of the conductive concrete is prolonged.
本发明涉及导电混凝土技术领域，且公开了一种碳纤维/碱激发复合压敏材料，包括以下重量份数配比的原料：氢氧化钠10‑20份、硅粉6‑12份、水40‑80份、分散剂0.8‑1.6份、消泡剂1‑2份、沙料30‑60份、电极片1份、碳纤维1份以及防护型涂料1份等。该碳纤维/碱激发复合压敏材料及其制备方法，通过将钛合金丝网加入浆体的内部，使得复合成型的复合压敏材料中均匀的分布有电极片，保障复合压敏材料的导电性，且使得导电混凝土的流动性降低，避免导电相团聚成簇，使得复合压敏材料加热均匀，并利用聚二甲基硅氧烷构成的消泡剂以及分散的碳纤维，从而减少导电混凝土中的孔隙，保障了游离水和各种离子在后期发生反应的稳定，从而使得导电混凝土的使用寿命。
