摘要

以未经任何处理的蔗渣为原料，硫氧镁水泥为胶黏剂，通过一步成型法制备硫氧镁水泥基蔗渣板，并探究氧硫比（活性氧化镁和七水硫酸镁的物质的量比）、胶料比（硫氧镁水泥和蔗渣的质量比）、热压温度、原料含水率及外加剂种类（乳化石蜡、氢氧化铝和磷酸二氢铵）对蔗渣板性能的影响。结果表明：在氧硫比为5，胶料比为3∶7，原料含水率为20%，热压温度为80 ℃的条件下，制备硫氧镁水泥基蔗渣板的密度为0.86 g/cm

，静曲强度为16 MPa，弹性模量为1 980 MPa，内结合强度为0.4 MPa，2 h吸水厚度膨胀率为4.6%，满足GB/T 39032—2020《难燃刨花板》中难燃P2型刨花板（干燥状态下使用的难燃家具型刨花板）的物理力学性能要求，甲醛释放量分级满足GB/T 39600—2021《人造板及其制品甲醛释放量分级》中E

级要求，燃烧性能达到GB 8624—2012《建筑材料及制品燃烧性能分级》中B

（B）级阻燃等级。外加剂磷酸二氢铵的加入有效提高了硫氧镁水泥基蔗渣板表面的抗泛霜性能。

Abstract

Using untreated bagasse as raw material and magnesium oxysulfide cement as adhesive

a one-step forming method was used to manufacture magnesium oxysulfide cement-based bagasse board (MOCBB). The effects of oxygen sulfur ratio (the ratio of active magnesium oxide and magnesium sulfate heptahydrate)

binder ratio (the mass ratio of magnesium oxysulfide cement and bagasse)

hot pressing temperature

moisture content of raw materials

and types of additives (emulsified paraffin

aluminum hydroxide

and ammonium dihydrogen phosphate) on the properties of bagasse board were investigated. The results showed that under the conditions of an oxygen-sulfur ratio of 5

a binder ratio of 3∶7

a raw material moisture content of 20%

and a hot pressing temperature of 80 ℃

the density

of the MOCBB was 0.86 g/cm

the modulus of rupture was 16 MPa

the modulus of elasticity was 1 980 MPa

the internal bonding strength was 0.4 MPa

and the 2-hour water thickness swelling rate was 4.6%

which met the physical and mechanical performance requirements of the flame-retardant P2 type fire-retardant particleboard (flame-retardant furniture type particleboard used in the dry state) in GB/T 39032—2020 "“

Difficult-flammable particleboard

”. The formaldehyde release classification met the E

level requirements in GB/T 39600—2021 “

Formaldehyde emission grading for wood-based panel and finishing products

”. The combustion performance met the B

(B) flame retardant level in GB 8624—2012 “

Classification for burning behavior of building materials and products

”. Adding of ammonium dihydrogen phosphate as an additive effectively improves the surface frost resistance of MOCBB.
