西北一号钢筋防锈涂料是一种水乳胶型热塑性与热固性复合的钢筋防锈漆,它是以环氧树脂改性丙—苯三元乳液为基料,并采取特殊工艺与乳液长期稳定,从而研制出云铁丙—苯这种适用于粉煤灰加气混凝土板材中钢筋的防锈涂料。通过对涂层厚度和致密性能、涂层的干燥速度、防锈性能、粘着力和附着力、耐盐雾、浸渍工艺以及毒性等项指标的试验研究,并经过实际试用结果表明各项技术性能均能达到预期要求。该项技术已于1984年4月通过了技术评议。该涂料主要技术指标为:干燥温度 >10℃(可自干或烘干);抗冲击强度50公斤-厘米,附着力(1毫米划格法) 100%;抗弯曲(弯心直径20毫米)未蒸>90°;盐水浸泡试验 10级,湿热试验≥9级,电化学测定涂层阻蚀作用良好;加气混凝土与钢筋粘结力11～20公斤力/厘米~2;足尺板室外暴露6个月试验钢筋网片无锈蚀;毒性试验未发现有毒性;储存期 6个月。
Northwest No. 1 steel anti-rust paint is a water emulsion type thermoplastic and thermosetting composite steel anti-rust paint, which is based on epoxy resin modified C - benzene ternary emulsion as the base material, and take a special process and emulsion long-term stability, In order to develop a cloud-iron-propylene-benzene, this kind of anti-rust coating is suitable for reinforcing steel in fly ash aerated concrete sheet. Through the experimental study on the thickness and denseness of the coating, the drying speed of the coating, the rust prevention performance, adhesion and adhesion, salt spray, impregnation process and toxicity, and the actual trial results show that the technical performance Can meet the expected requirements. The technology passed the technical review in April 1984. The main technical indicators of the paint: drying temperature> 10 °C (dry or dry); impact strength 50 kg-cm, adhesion (1 mm cross-cut method) 100%; bending resistance (bending heart diameter 20 mm) Unsteamed>90°;Brine immersion test 10,Damp heat test ≥9, Electrochemical determination of coating corrosion resistance is good; Adhesive strength of reinforced concrete with air steel 11 to 20 kgf/cm~2; Full-foot board outdoor 6 months after the test, the steel mesh was not rusted; no toxicity was found in the toxicity test; the storage period was 6 months.
