Abstract

The utility model discloses heavy type timberwork timber which comprises a reorganization bamboo body (1). Carbon fiber layers (2) are respectively arranged on the upper surface and the lower surface of the reorganization bamboo body (1). Bamboo pieces (3) are respectively arranged on outer sides of the carbon fiber layers (2). A nanometer SiO2 modified polyurethane coating (4) is uniformly attached to the periphery of the heavy type timberwork timber. The heavy type timberwork timber is attractive in appearance material quality, reliable in performance, environment-friendly, abrasion-resistant and waterproof.

Description

A kind of heavy timber construction material

Technical field

The utility model relates to a kind of engineering material, particularly a kind of environmental protection, wear-resisting, water-fast heavy timber construction material.

Background technology

In building construction project process, people often use the reorganization bamboo as the engineering material, it in use has pernicious gases such as release formaldehyde, harm environment and health, burning easily, influence the scope of application and the safety of basket weaver Cheng Cai, and in wet environment, go mouldy easily, influence application life.

The utility model content

Technical problem to be solved in the utility model is that a kind of outer surface material is attractive in appearance, dependable performance, environmental protection, wear-resisting, water-fast heavy timber construction material.

In order to solve the problems of the technologies described above, the heavy timber construction material that the utility model provides comprises reorganization bamboo body, and described reorganization bamboo body upper and lower surface is respectively equipped with carbon fiber layer, the described carbon fiber layer outside is respectively equipped with bamboo chip, and the whole body evenly is attached with one deck nanometer SiO ₂Modified polyurethane coating.

Glued together by epoxy resin between each layer.

The thickness of described reorganization bamboo body is 30.0mm～60.0mm, and the thickness of described carbon fiber layer is 5.0mm～8.0mm, and the thickness of described bamboo chip is 5.0mm～8.0mm, described nanometer SiO ₂The thickness of modified polyurethane coating is 0.8mm～1.2mm.

Adopt the heavy timber construction material of technique scheme, because the intake of pernicious gases such as carbon fiber layer PARA FORMALDEHYDE PRILLS(91,95) is very high, can effectively adsorb the pernicious gas that the reorganization bamboo discharges, can effectively improve fire resistance simultaneously; The whole body is evenly adhered to nanometer SiO2 modified polyurethane coating and can effectively be stoped the outside release of pernicious gas and stop extraneous moisture to enter, and good abrasion resistance is arranged simultaneously, and that bamboo chip has is good ornamental, satisfies the requirement of viewing and admiring in using.The thickness of reorganization bamboo body is 30.0mm～60.0mm, and the thickness of carbon fiber layer is 5.0mm～8.0mm, and the thickness of bamboo chip is 5.0mm～8.0mm, nanometer SiO ₂The thickness of modified polyurethane coating is 0.8mm～1.2mm, better effects if.

In sum, the utility model be that a kind of outer surface material is attractive in appearance, dependable performance, environmental protection, wear-resisting, water-fast heavy timber construction material.
