The invention relates to the field of building ceramic production and manufacturing, in particular to a dry-method ceramic wall and floor tile green body reinforcing agent with an early strength effect and an application process, and aims to solve the problem of high green body damage rate caused by insufficient early strength of large-size ceramic wall and floor tiles manufactured by a dry-methodprocess. The process comprises the following steps: taking 0.1-0.5 wt.% of chlorine early strength agent and 0.1-0.5 wt.% of silicon early strength agent, 0.01 wt.%-0.05 wt.% of an organic early strength agent and 0.1 wt.%-0.4 wt.% of modified starch, putting the early strength agent mixture and the modified startch in a stirrer for 30-60 minutes, uniformly adding about 10%-15% of water into thepowder by using a spraying method, carrying out stirring, granulating, sieving with a 40-mesh sieve, drying the powder in an oven at 80-100 DEG C for 10-20 minutes, and cooling to obtain particles with the water content of about 6%-10%, and aging for 24h under a loosening state for brick pressing. The early strength of the ceramic green body can be improved by 30%-60% according to the formula of the ceramic green body. The reinforcing agent has the advantages of stable effect, small ash remaining amount after firing, small influence on the structure of the ceramic, and wide application in further.
本发明涉及建筑陶瓷生产制造领域，特别涉及到一种具有早强效应的干法制陶瓷墙地砖坯体的增强剂及应用工艺，针对干法工艺制大规格陶瓷墙地砖出现的早期强度不足，而导致的生坯破损率高问题，取0.1wt.％～0.5wt.％氯系早强剂，0.1wt.％～0.5wt.％硅系早强剂，0.01wt.％～0.05wt.％有机早强剂、0.1wt.％～0.4wt.％改性淀粉，将复合的早强剂与粉料一起放入搅拌机内混合30min～60min，然后用喷雾法将10％～15％左右的水均匀加入粉料中进行搅拌造粒，过40目筛，然后将粉料置于80‑100℃的烘箱内干燥10～20min，冷却后得到含水量约为6％‑10％的粒子，并保持疏松状态下陈腐24h进行压砖，其配方可提高陶瓷生坯的早期强度30％～60％。本发明效果稳定，且在烧制后留灰量少，对陶瓷本身结构影响较小，有广泛的应用前景。
