热固性改性聚苯板的应用方法!
作者:admin 来源:本站 发布时间:2019-10-15 15:17:30 浏览次数:241
  近年来,在建筑保温市场中,出现了生产企业和通过使用酚醛橡胶和防火涂料涂覆聚苯乙烯颗粒来提高聚苯乙烯板的防火性能的热固性改性聚苯乙烯板,地方建筑主管部门,施工图审查机构等也已出现。 该部门已就热固性改性聚苯乙烯板的性能进行了咨询。
In recent years, in the building heat preservation market, there have been production enterprises and thermosetting modified polystyrene boards which can improve the fire resistance of polystyrene boards by coating polystyrene particles with phenolic rubber and fire retardant coatings. Local building authorities and construction drawing review agencies have also appeared. The Department has consulted on the properties of thermosetting modified polystyrene board.
为此,江苏省住房和城乡建设部技术开发中心在南京举办了热固性改性聚苯乙烯板研讨会,住房和城乡建设部科技工业化发展中心。 物资协会和江苏省公安消防总队技术。 江苏省建筑工程质量监督站,江苏省建筑工程设计施工图审查中心,南京建筑设计研究院有限公司,江苏省建筑科学研究院,南京大学,江苏省建筑工程质量检验中心有限公司 江苏省建筑材料建筑质量检测中心,雅仕创能科技有限公司,山东盛泉化工有限公司,江苏兆盛建材有限公司和巴斯夫相关负责人 ()有限公司参加了会议。 与会者就现有的热固性改性聚苯乙烯板的开发,生产,标准,测试,工程应用和市场管理以及热固性改性聚苯乙烯板的技术路线和燃烧性能进行了深入的讨论。 形成共识和建议:
To this end, the Technical Development Center of the Ministry of Housing and Urban-Rural Construction of Jiangsu Province held a seminar on thermosetting modified polystyrene boards in Nanjing, and the Science and Technology Industrialization Development Center of the Ministry of Housing and Urban-Rural Construction of China. Material Association and Jiangsu Provincial Public Security Fire Brigade Technology. Jiangsu Construction Quality Supervision Station, Jiangsu Construction Engineering Design and Construction Drawing Review Center, Nanjing Architectural Design Research Institute Co., Ltd., Jiangsu Academy of Architectural Sciences, Nanjing University, Jiangsu Construction Engineering Quality Inspection Center Co., Ltd. Jiangsu Construction Material Construction Quality Inspection Center, Yashi Creative Energy Technology Co., Ltd., Shandong Shengquan Chemical Co., Ltd., Jiangsu Province, China Su Zhaosheng Building Material Co., Ltd. and BASF related responsible person (China) Co., Ltd. participated in the meeting. Participants discussed in depth the development, production, standards, testing, engineering application and market management of existing thermosetting modified polystyrene boards, as well as the technical routes and combustion performance of thermosetting modified polystyrene boards. Forming consensus and recommendations:
1.用酚醛和防火涂料改性聚苯乙烯板,以形成热固性改性聚苯乙烯板。 在保持聚苯乙烯板的热性能的条件下,在着火的情况下可以减少液滴,并且可以改善材料。 防火性能,技术路线是可行的,对丰富外墙保温材料的种类具有积极意义。

Under the condition of keeping the thermal properties of polystyrene board, droplets can be reduced and materials can be improved under the condition of ignition. Fire-proof performance, technical route is feasible, to enrich the types of exterior wall insulation materials have a positive significance.

2.在现有技术和生产工艺设备的条件下,热固性改性聚苯乙烯板的热导率小于或等于0.036W /(m·K),当表观密度小于50kg / m3时, 燃烧性能等级为B1。  ,无法达到A级。
2. The thermal conductivity of thermosetting modified polystyrene board is less than or equal to 0.036W/(m.K) under the existing technology and production equipment. When the apparent density is less than 50kg/m3, the combustion performance grade is B1. It can't reach grade A.
3.建议制定统一的技术标准,包括表观密度,燃烧性能等级,热固性性能,导热系数等指标,以指导和规范热固性改性聚苯乙烯板的工程应用。
3. It is suggested that a unified technical standard should be established, including apparent density, combustion performance grade, thermosetting performance and thermal conductivity, to guide and standardize the engineering application of thermosetting modified polystyrene board.
4.在实际应用中,应强调热固性改性聚苯乙烯板的燃烧性能与其他性能之间的对应关系。 热性能,物理性能和燃烧性能测试必须在同一组样品中和同一部分中进行。 在报告中发布。 当单独进行燃烧性能测试时,必须在测试报告中注明样品的表观密度。 当燃烧性能和热性能测试报告所指示的表观密度不一致时,不应使用燃烧性能测试报告。
4. In practical application, the relationship between combustion performance and other properties of thermosetting modified polystyrene board should be emphasized. Thermal, physical and combustion performance tests must be carried out in the same group of samples and in the same part. Published in the report. When the combustion performance test is carried out separately, the apparent density of the sample must be indicated in the test report. When the apparent density indicated in the combustion performance and thermal performance test report is inconsistent, the combustion performance test report should not be used.
