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...

Examples

Embodiment 1

[0058] The novel OSB structure building formwork of the present application, structure such as figure 1 shown.

[0059] A preparation method of a novel OSB structure building formwork, comprising the following steps:

[0060] (1) According to the calculation in parts by mass, take 100 parts of pine rough flakes and fine flakes base material, the ratio of coarse flakes and fine flakes base material is 1:1, and the fine flakes are mainly used as filling (length 50-100mm , 25-50mm wide 50 parts of fine shavings, 100-150mm long, 50 parts of wide 50-75mm coarse shavings), 2 parts of emulsified paraffin, 15 parts of organic glue, 2 parts of tackifier, 4 parts of reinforcing fiber, 5 parts water;

[0061] (2) Put the two base materials of coarse shavings and fine shavings into a high-speed mixer for stirring. During the stirring process, use different spray guns to mix the above-mentioned additives such as organic glue, adhesive, emulsified paraffin, reinforcing fiber, and water in...

Embodiment 2

[0078] A new type of OSB structure building formwork, similar to Example 1, the difference is that it includes the following raw materials in parts by weight: 85 parts of planed base material, 2 parts of waterproofing agent, 10 parts of organic glue, 1 part of adhesive, 3 parts of water, 2 parts of reinforcing fiber, 1 part of hot-melt plastic particles.

Embodiment 3

[0080] A new type of OSB structure building formwork, similar to Example 1, the difference is that it includes the following raw materials in parts by weight: 90 parts of planed base material, 2.5 parts of waterproofing agent, 12 parts of organic glue, 1.5 parts of adhesive, 4 parts of water, 3 parts of reinforcing fiber, 1.5 parts of hot-melt plastic particles.
