AI Technical Summary

Problems solved by technology

There have been a large number of reports on the use of inorganic nano-ultraviolet absorber coatings to improve the light aging resistance of wood and bamboo. Inorganic nano-ultraviolet absorbers have relatively good ultraviolet light shielding ability and a certain degree of antibacterial performance. Surface-modified nanoparticles can achieve a better dispersion effect, but at the same time it reduces the coating's ability to absorb ultraviolet light

Embodiment

[0030] Embodiment: a kind of anti-aging outdoor recombinant bamboo manufacturing method comprises the following steps:

[0031] 1 Bamboo substrate preparation process:

[0032] 1) Unit preparation: directional separation of fibers, sawing the moso bamboo into 2.6m long bamboo tubes, dissecting it into bamboo slices and removing green (if you need to keep the green color of bamboo, the step of removing green is not required), and disperse to make bamboo bundles .

[0033] 2) Bamboo bundle woven curtain: use manual or mechanical weaving into large bamboo bundle pieces. The feeding speed of mechanical knitting is 5m / min, and the needle gap is 25mm.

[0034] 3) Bamboo curtain / bundle heat treatment: place bamboo curtain / bamboo bundle in water vapor or other inert gas or oil bath for heat treatment, the treatment temperature is 160-220°C, and the treatment time is 0.5-6h.

[0035] 4) Glue dipping: place the bamboo bundle curtain / bamboo bundle dried to a moisture content of 6%-8% ...

Embodiment 2

[0054] Embodiment 2: adopt the product of above-mentioned light aging resistance outdoor recombinant bamboo manufacture method, as attached figure 1 As shown, it includes an outdoor reorganized bamboo base material 2 spliced ​​and pasted by bamboo bundles 1. There are 2-3 layers of UV curable primer layer 3 above the outdoor restructured bamboo base material 2, and 1-3 layers of UV curable primer layer 3 are provided above the UV curable primer layer 3. 3 layers of sanding primer layer 4, 2-4 layers of UV curing topcoat layer 5 are arranged above the sanding primer layer 4.

Abstract

The invention discloses a light-ageing-resistant outdoor recombined bamboo manufacturing method. The light-ageing-resistant outdoor recombined bamboo manufacturing method successively comprises the following steps: unit preparation, gum dipping, assembling, hot press molding and saw cutting. In addition, the light-ageing-resistant outdoor recombined bamboo manufacturing method further comprises treatment on outdoor recombined bamboo base materials by using a mildew-retarding agent and a technology of coating light-ageing-resistant outdoor recombined bamboo. The light-ageing-resistant outdoor recombined bamboo manufacturing method has excellent light-ageing-resistant effect, mildew resistance and dimensional stability, can effectively protect the base materials against being aged due to ultraviolet rays, the service life of outdoor bamboo is prolonged, the application range of the bamboo is expanded, the additional value of bamboo products is increased, and deforestation is reduced. The light-ageing-resistant outdoor recombined bamboo manufacturing method has predominant economic benefit and ecological benefit.

Description

technical field [0001] The invention relates to a manufacturing method and product of bamboo products, in particular to a manufacturing method and product of outdoor recombined bamboo resistant to light aging, and belongs to the technical field of bamboo product production technology. Background technique [0002] Bamboo is loved by people because of its beautiful texture, high strength-to-weight ratio, and strong machinability. In recent years, due to the crisis of exhaustion of traditional building material resources, the Ministry of Industry and Information Technology and the Ministry of Housing and Urban-Rural Development have proposed to vigorously develop biomass green building materials. Bamboo and wood building materials have become one of the future development directions of the construction industry and the only way to accelerate transformation and upgrading. Outdoor products such as outdoor wooden flooring and wooden exterior wall decoration materials are also inc...
