Example Embodiment
[0057] Example 1
[0058] The new OSB structure building template for this application, structure figure 1 Indicated.
[0059] A new type of OSB structure building template, including the following steps:
[0060] (1) According to the quality calculation, take 100 pine wood coarse planing and fine planer, coarse planing and fine planing base ratio of 1: 1, the fine planing is mainly filled (length 50-100mm) 50 parts of 25-50mm, 50 parts, 50-75mm, width, 50-75mm wide planer), 2 emulsified paraffin, 15 organic glue, 2 tackifiers, 4 reinforcing fibers, 5 parts water;
[0061] (2) Two bases of crude planing and fine planing are separately placed in a high-speed mixer, and the above additives such as organic water, adhesive, emulsified paraffin, enhance fiber, and water during agitation. The mixer is added sequentially (after multiple experiments, the change in the above material adding sequence has a significant effect on the end of the finally prepared building template, adding in th...

Abstract
The invention provides a novel OSB structure building template and a preparation method thereof. The novel OSB structure building template comprises an oriented strand board layer, a hot-melt plasticlayer and a wear-resisting layer and is prepared from, by weight, 85-115 parts of flaking base materials, 2-5 parts of waterproof agents, 10-85 parts of organic glue, 1-4 parts of tackifiers, 3-9 parts of water, 2-6 parts of reinforcing fibers and 1-2.5 parts of hot-melt plastic particles. Compared with a traditional plywood thermoplastic extrusion molding process that the surface of a product needs to be punched to form a plastic surface layer, the OSB surface layer does not need to be punched or subjected to extrusion molding, surface gaps are directly filled with hot melting type plastic particles, and a wear-resisting layer is flatly laid on the upper surface of the OSB surface layer to prevent a steel plate from being bonded during hot pressing. The prepared novel OSB structure building template is good in waterproof performance and high in strength. The impact resistance and the bending resistance are high, and the turnover frequency of the building template and the wood utilization rate are obviously improved.
Description
technical field [0001] The invention belongs to the technical field of building materials, and in particular relates to a novel OSB structure building formwork and a preparation method thereof. Background technique [0002] Building formwork is the main tool for the construction of concrete structures. It usually plays the role of support and protection in the pouring process. It consumes a lot in construction projects. Formwork technology directly affects the quality and cost of construction projects. Therefore, it is the key to promoting the progress of construction technology. an important content. [0003] In recent years, my country's real estate industry has developed rapidly, and building templates have also developed rapidly. At present, the commercial building formwork is mainly composed of wood formwork. The traditional wood formwork is light in weight, good in versatility, and low in price, but its mechanical properties are very limited. The lifespan is short, w...
