Description
技术领域 technical field
本发明涉及建筑材料，具体涉及一种适用于厂房建筑的轻质防火保温型复合板。 The invention relates to building materials, in particular to a light-weight, fire-proof and heat-retaining composite board suitable for factory buildings.
背景技术 Background technique
目前,市场上常见的建筑用板材有泡沫复合板、水泥板、现浇板、聚苯板等。随着高层建筑、大型厂房、框架建筑的推广，建筑行业对板材的要求也越来越高。 At present, the common building boards on the market include foam composite boards, cement boards, cast-in-place boards, and polystyrene boards. With the promotion of high-rise buildings, large factory buildings, and frame buildings, the requirements for panels in the construction industry are also getting higher and higher.
现有的水泥板、混凝土板或者现浇板，具有防火能力强的特点，但是存在板材重量大，防水和隔热效果差的缺陷；泡沫复合板具有重量小的优点，但是保温效果差，尤其存在遇高温或减明火易燃的致命缺点；聚苯板存在保温效果好的优点，但是承重和防火能力弱。 Existing cement boards, concrete boards or cast-in-place boards have the characteristics of strong fire resistance, but have the defects of heavy board weight, poor waterproof and heat insulation effect; foam composite boards have the advantage of small weight, but poor heat preservation effect, especially There is a fatal disadvantage of being flammable when exposed to high temperature or reduced open flame; polystyrene board has the advantage of good thermal insulation effect, but its load-bearing and fireproof ability is weak.
发明专利“一种轻质保温防火复合板及其生产方法（CN102155070B）”，公开了芯板以快硬硫铝酸盐水泥和粉煤灰为主料的技术方案，但是，由于主料仍然为水泥，所以依然存在板材本身重量大的缺陷，而且水泥的保温效果比较差。 The invention patent "A light-weight thermal insulation and fireproof composite board and its production method (CN102155070B)" discloses a technical scheme in which the core board uses rapid hardening sulphoaluminate cement and fly ash as the main materials. However, since the main materials are still Cement, so there is still the defect that the board itself is heavy, and the insulation effect of cement is relatively poor.
发明专利“一种建筑复合板的制备方法（CN102249634B）”，公开了一种以18.5份石灰粉、26份核桃壳、20份石膏粉为主要材料制作的板材，主要用于非承重内外墙板，存在承重能力弱，保温效果不是很好的缺点。 The invention patent "A Preparation Method of Building Composite Board (CN102249634B)" discloses a board made of 18.5 parts of lime powder, 26 parts of walnut shell and 20 parts of gypsum powder as main materials, mainly used for non-load-bearing interior and exterior wall panels , has the disadvantages of weak load-bearing capacity and poor thermal insulation effect.
综上所述，为了解决现有建筑用板材无法同时满足质量轻、承重能力强、防火保温的要求，而研发了一种新型的建筑板材。 To sum up, in order to solve the problem that the existing building panels cannot meet the requirements of light weight, strong load-bearing capacity, fire protection and heat preservation at the same time, a new type of building panels has been developed.
发明内容 Contents of the invention
本发明是为了解决现有建筑用板材无法同时满足质量轻、承重、防火、保温能力好的要求的问题，的而提供了一种轻质防火保温型复合板。 The invention aims to solve the problem that the existing building boards cannot meet the requirements of light weight, load bearing, fire prevention and good heat preservation ability at the same time, and provides a lightweight fireproof and heat preservation composite board.
本发明是通过以下技术方案实现的： The present invention is achieved through the following technical solutions:
一种轻质防火保温型复合板，原料包括20-90份的石膏粉、1-8份的石膏纤维、2-9份的粉煤灰、0.2-0.6份的发泡剂、0.1-1.5份的十二烷基磺酸钠，由下述方法制备获得：将粉煤灰研磨粉碎，与石膏粉、石膏纤维混合和溶于水，控制温度在20-40℃，加入发泡剂搅拌5-8min，然后升温至100-110℃，加入十二烷基磺酸钠，继续搅拌5-8min，得到夹心料，然后在两层面料层中间铺装、加压成型，即得。 A lightweight fire-proof and heat-retaining composite board, the raw materials include 20-90 parts of gypsum powder, 1-8 parts of gypsum fiber, 2-9 parts of fly ash, 0.2-0.6 parts of foaming agent, 0.1-1.5 parts of Sodium dodecyl sulfonate is prepared by the following method: pulverize fly ash, mix with gypsum powder and gypsum fiber and dissolve in water, control the temperature at 20-40°C, add foaming agent and stir for 5- 8 minutes, then raise the temperature to 100-110°C, add sodium dodecyl sulfonate, and continue to stir for 5-8 minutes to obtain a sandwich material, which is then paved between two layers of fabric layers and pressurized to form a product.
进一步地，上述轻质防火保温型复合板，优选原料包括85份石膏粉，5.5份石膏纤维，7份粉煤灰，0.3份发泡剂，0.8份十二烷基磺酸钠。 Further, the preferred raw materials for the above-mentioned lightweight fireproof and thermal insulation composite board include 85 parts of gypsum powder, 5.5 parts of gypsum fiber, 7 parts of fly ash, 0.3 part of foaming agent, and 0.8 part of sodium dodecylsulfonate.
所述的石膏粉为高强石膏粉，因为石膏本身具有保温、防火、质轻、绝缘、易加工、呼吸功能、装饰性好的特点，当使用高强石膏粉为原料时，由于高强石膏粉硬化后孔隙率小，与乳化剂十二烷基磺酸钠作用后，制得的板材在保持普通石膏粉优点的基础上，还进一步强化了板墙的强度。 The gypsum powder is high-strength gypsum powder, because gypsum itself has the characteristics of heat preservation, fire prevention, light weight, insulation, easy processing, breathing function, and good decoration. When high-strength gypsum powder is used as raw material, it will The porosity is small, and after the emulsifier sodium dodecyl sulfonate acts on it, the prepared board not only maintains the advantages of ordinary gypsum powder, but also further strengthens the strength of the board wall.
所述的粉煤灰是研磨粉碎的低品位粉煤灰，粒度为0.3-3mm，比表面积为350-500m2/Kg，化学成分的质量百分比为，SiO238-45%，CaO48-50%。 The fly ash is ground and pulverized low-grade fly ash with a particle size of 0.3-3mm, a specific surface area of 350-500m 2 /Kg, and a mass percentage of the chemical composition of SiO 2 38-45%, CaO 48-50% .
所述的发泡剂为泡沫混凝土发泡剂。 The foaming agent is foam concrete foaming agent.
本发明使用了1-8份的石膏纤维作为一种辅助填料，由于石膏纤维集增强纤维和超细无机填料二者的优势于一体，在制作板材时，在添加上述重量份的石膏纤维情况下，不仅可起到补强增韧的作用，同时还可起到保温、阻燃、耐火隔热的作用。 The present invention uses 1-8 parts of gypsum fiber as an auxiliary filler. Since the gypsum fiber combines the advantages of reinforcing fibers and ultrafine inorganic fillers, when making boards, the above weight parts of gypsum fiber are added. , can not only play the role of reinforcement and toughening, but also play the role of heat preservation, flame retardancy, fire resistance and heat insulation.
为了验证本发明产品的性能，分别测定了产品的体积密度、抗压强度、可燃性、导热系数、传热系数、防火性能，其中所用石膏粉为高强度石膏粉，2小时抗折强度是5.0-6.0MPa，2小时抗压强度是15-18MPa，添加辅料板材的抗折，抗压强度有所下降，实际检测抗压强度可达到7.5-10.5MPa，防火性能达到不燃A级，其中10cm厚导热系数为0.05-0.1W/m2.K。 In order to verify the performance of the product of the present invention, the bulk density, compressive strength, flammability, thermal conductivity, heat transfer coefficient, and fire resistance of the product were measured respectively, wherein the gypsum powder used was high-strength gypsum powder, and the 2-hour flexural strength was 5.0 -6.0MPa, the 2-hour compressive strength is 15-18MPa, the flexural resistance of the board added with auxiliary materials, the compressive strength has decreased, the actual test compressive strength can reach 7.5-10.5MPa, and the fire resistance can reach the non-combustible A level, of which 10cm thick The thermal conductivity is 0.05-0.1W/m 2 .K.
与现有技术相比，本发明制备方法简单，易于操作，产品应用范围广，尤其适用于建筑工棚、厂房，质量轻、强度高，并具有很好的保温防火性，可彻底规避明火燃烧等风险。 Compared with the prior art, the preparation method of the present invention is simple, easy to operate, and has a wide range of product applications. It is especially suitable for construction sheds and workshops. It has light weight, high strength, good heat preservation and fire resistance, and can completely avoid open flame burning, etc. risk.
