High-strength building material and preparation method thereof
The invention relates to a high-strength building material and a preparation method thereof, and belongs to the technical field of building materials, the high-strength building material comprises the following raw materials by weight: 150-160 parts of a premix, 4-6 parts of an auxiliary agent, 30-40 parts of mixed powder, 50-60 parts of modified urea resin, 4.2-4.4 parts of a foaming agent and 4-6 parts of a surfactant; the raw materials are mixed and injected into a mold, and the high-strength building material is obtained after foaming, drying, curing and demolding. Aiming at some defects of traditional building thermal insulation materials including organic thermal insulation materials and inorganic thermal insulation materials in the prior art, urea-formaldehyde resin is modified, the water resistance of the urea-formaldehyde resin is improved, amino and formaldehyde in a modifier structure are subjected to an addition reaction, organic silicon and fluorine are introduced into the structure of the urea-formaldehyde resin, and the water resistance of the urea-formaldehyde resin is improved. The water resistance, oil resistance and aging resistance of the urea-formaldehyde resin are improved, the crosslinking degree of the modified urea-formaldehyde resin is improved, and the mechanical property of a building material is improved.
本发明涉及一种高强度建筑材料及其制备方法，属于建筑材料技术领域，该材料包括如下重量份原料：150‑160份预混物、4‑6份助剂、30‑40份混合粉料、50‑60份改性脲醛树脂、4.2‑4.4份发泡剂和4‑6份表面活性剂；将原料混合注入模具中，经过发泡、干燥、固化和脱模后得到一种高强度建筑材料。针对现有技术中传统的建筑保温材料包括有机保温材料和无机保温材料存在的一些缺陷，对脲醛树脂进行改性，提高其耐水性能，该改性剂结构中的氨基和甲醛发生加成反应，在脲醛树脂的结构中引入有机硅和氟，提高脲醛树脂的耐水、耐油、耐老化性，提高了改性脲醛树脂的交联度，改善了建筑材料的力学性能。
