Magnesian cementing material for hand lay-up glass fiber reinforced plastic mold
The invention discloses a magnesium cementing material for a hand lay-up glass fiber reinforced plastic mold. The magnesium cementing material comprises, by mass, 100 parts of magnesium oxide powder with the active content of 60% or above, 100-120 parts of a magnesium chloride solution with the mass concentration of 20-23% or 110-130 parts of a magnesium sulfate solution with the mass concentration of 21-24%, 2-3 parts of an additive, 20-40 parts of a filler and 5-15 parts of plant fibers. The inorganic magnesium cementing material is prepared from inorganic raw materials, the inorganic glass fiber reinforced plastic mold prepared from the inorganic magnesium cementing material is environment-friendly and low in cost, has no harm to the environment during production and use, and can be arbitrarily filled into the sea, and a certain amount of waste can be mechanically crushed and then added into cement to serve as a filling material of the product to realize the recycling of raw material products. The cost of the inorganic glass fiber reinforced plastic mold made of the inorganic magnesium cementing material is 1/10 to 1/15 of that of an organic glass fiber reinforced plastic mold, and the inorganic glass fiber reinforced plastic mold is high in strength and durability and has high practicability and wide applicability.
一种手糊玻璃钢模具用的镁质胶凝材料，质量组份包括：活性含量在60％以上的氧化镁粉100份，质量浓度为20‑23％的氯化镁溶液100‑120份或质量浓度为21‑24％的硫酸镁溶液110‑130份，外加剂2‑3份，填料20‑40份，植物纤维5‑15份。其通过使用无机原料制得无机镁质胶凝材料，用该材料制成的无机玻璃钢模具绿色环保、成本低，生产和使用不会对环境有任何危害，可任意填埋填海，达到一定量的废弃物还可以机械粉碎后，加入水泥中做产品的填充料，做到原料产品的循环使用。用无机镁质胶凝材料制造的无机玻璃钢模具是有机玻璃钢模具成本的1/10‑1/15，强度高，耐用性强，具有很强的实用性和广泛的适用性。
