The invention discloses an additive for building materials, which is prepared from the following components in parts by weight: 15 to 20 parts of polyvinyl alcohol, 10 to 15 parts of Arabic gum, 5 to 8 parts of FC dispersing agent, 5 to 10 parts of kerosene and 3 to 5 parts of oleic acid. The FC dispersing agent comprises terpilenol and ethyl cellulose, and the weight ratio of the terpilenol to the ethyl cellulose is (15-20): 1. According to the invention, by preparing the composite additive, the additive can be uniformly distributed to each particle, and a homogenized microstructure is formed in the particle, so that the particle surface is smooth, the gap is small, and the particle is easy to compact and compact after the powder is pressed and granulated.
本发明公开了一种建筑材料用添加剂，所述添加剂包括聚乙烯醇、阿拉伯树胶、FC分散剂、煤油和油酸，各组分所占的重量份如下：所述聚乙烯醇：15～20份，所述阿拉伯树胶：10～15份，所述FC分散剂：5～8份，所述煤油：5～10份，所述油酸：3～5份；所述FC分散剂包括松油醇和乙基纤维素，所述松油醇与所述乙基纤维素的重量比为15～20:1。本发明通过配制复合添加剂，使得添加剂能够均匀地分给每个粒子，在颗粒内形成均质化的微观结构，使得粉料在压制造粒后颗粒表面平整、间隙小，易于压密压实。
