Preparation method of expanded perlite insulation board
The invention discloses a preparation method of an expanded perlite insulation board. The preparation method of the expanded perlite insulation board comprises the following specific steps: (1) preparation of an adhesive: mixing and stirring an organic adhesive, an inorganic adhesive, aluminum hydroxide and water according to a weight ratio of 10: 7: 3: 12 to obtain an adhesive solution; (2) burdening: mixing and stirring the adhesive solution obtained in the step (1) and expanded perlite according to a weight ratio of 1: 4 to obtain a mixture; (3) molding: subjecting the mixture obtained in the step (2) to standing for 8-12 minutes, putting the mixture into a mold, and performing compression molding; (4) drying: feeding an expanded perlite insulation board molded in the step (3) into a drying oven, then raising the temperature of the drying oven to 230 DEG C and keeping the temperature for 2 hours; and (5) cooling: cooling the dried expanded perlite insulation board to room temperature. The expanded perlite insulation board prepared by the preparation method disclosed by the invention has good pressure resistance and insulation performance.
本申请公开了一种膨胀珍珠岩保温板的制备方法。该膨胀珍珠岩保温板的制备方法，其具体步骤如下：(1)、粘结剂的配置：将有机粘结剂、无机粘结剂、氢氧化铝和水按照重量10：7：3：12的比例混合搅拌得粘结剂溶液；(2)、配料：将步骤(1)所得的粘结剂溶液与膨胀珍珠岩按照重量1：4的比例混合搅拌得到混合料；(3)、成型：将步骤(2)得到的混合料静置8～12min后装入模具，然后压制成型；(4)、烘干：将步骤(3)成型的膨胀珍珠岩保温板送入烘箱，然后将烘箱的温度升高到230℃并保持2h；(5)、冷却：将烘干后膨胀珍珠岩保温板冷却到室温。本发明所述的制备方法制备所得膨胀珍珠岩保温板具有良好耐压和保温性能。
