High-solid-content simulated lunar soil paste material with excellent rheological and retention characteristics and preparation method thereof
The invention discloses a high-solid-content simulated lunar soil paste material with excellent rheological and retention characteristics and a preparation method thereof, the high-solid-content simulated lunar soil paste material comprises a premixed liquid and simulated lunar soil powder, and the weight ratio of the premixed liquid to the simulated lunar soil powder is 1: (78-82); the premixed solution comprises 90-95 parts of photosensitive resin, 5-10 parts of a wetting dispersant, 3-5 parts of water, 3-5 parts of a defoaming agent and 1-5 parts of a photoinitiator. According to the high-solid-content simulated lunar soil paste material, on the basis of the emulsification action principle of two immiscible liquids, a certain proportion of aqueous solution is introduced, under the action of the wetting dispersant, an oriented molecular layer is formed on a water and resin interface, emulsification occurs, then surface tension is reduced, and the high-solid-content simulated lunar soil paste material is obtained according to a Gibbs adsorption formula. The problem that the viscosity of a high solid phase is difficult to reduce is well solved, and photocuring printing of the simulated lunar soil paste with the solid content of 62 vol% is achieved by combining an SLA photocuring technology.
本发明公开了一种具备优良流变与滞留特性的高固含量模拟月壤膏料及其制备方法，该高固含量模拟月壤膏料包括预混液及模拟月壤粉末，预混液与模拟月壤粉末的重量比为1：(78‑82)；预混液包括光敏树脂90份‑95份，润湿分散剂5份‑10份，水3份‑5份，消泡剂3份‑5份，光引发剂1份‑5份。上述高固含量模拟月壤膏料基于两种互不相溶液体的乳化作用原理，通过引入一定比例的水溶液，在润湿分散剂的作用下，使得水与树脂界面形成定向分子层并发生乳化进而降低表面张力，依据吉布斯吸附公式，较好的解决了高固相难以降低粘度的难题，再结合SLA光固化技术，实现了固含量达62vol％的模拟月壤膏料的光固化打印。
