Non-corrosive fire-resistant steel door cement core plate and preparation method thereof
The invention discloses a non-corrosive fire-resistant steel door cement core plate, which belongs to the field of cement core plates and comprises the following components in percentage by mass: 50 to 70% of cement, 20 to 40% of water, 3 to 7% of a foaming agent, 0.3 to 1% of fiber, 2 to 5% of an auxiliary agent and 0.01 to 0.5% of a catalyst. All detection standards can meet the use requirements, the water content of the core plate is not high, so that the water content can be reduced to be below 12% after 7 days of blowing maintenance, basically no powder is left on the surface of the core plate after blowing, no cavitation phenomenon is generated during bonding and hot pressing of the steel fireproof door, In the use period after installation, additives which easily generate odor and negative ions which easily corrode steel such as chloride ions are not added into the fireproof door core plate, and the situations that the steel is corroded and odor occurs are avoided.
本发明公开了一种无腐蚀的耐火性钢质门水泥芯板，属于水泥芯板领域，包括如下质量百分比的各组分：包括如下质量百分比的各组分：水泥为50‑70％，水20‑40％，发泡剂3‑7％，纤维0.3‑1％，助剂2‑5％，催化剂0.01‑0.5％。所有检测标准均能达到使用要求，因芯板本身含水率就不高，故吹风养护7天后含水率能降低到12％以下，芯板表面经过吹扫后基本无粉末残留，钢质防火门粘结热压时不会产生空泡现象，安装后使用期间内，防火门芯板未加入含易产生臭气的添加剂以及氯离子等易腐蚀钢材的阴离子，不会出现腐蚀钢材、有臭味出现的情况。
