Problems solved by technology

However, the cost of phenolic resin is high, the color of the adhesive layer is darker, the curing temperature is high, and the time is long, so it is limited in use.
Melamine formaldehyde resin has higher heat resistance, water resistance, abrasion resistance, aging resistance, and corrosion resistance than urea-formaldehyde resin and phenolic resin, and the curing speed is fast. It can also be cured by heating and curing at room temperature without curing agent; its disadvantage is that it is non-toxic. Brittle and easy to crack, high cost
At present, the traditional process uses polyvinyl alcohol as a modifier for toughening, but polyvinyl alcohol is irritating, flammable, and difficult to transport and store
In addition, the biggest difficulty in the research is the determination of its component ratio, reaction temperature, time, pH value and addition method, etc.
However, resin impregnation treatment can effectively improve the strength of rattan, but at the same time it will greatly damage the unique toughness of rattan

Embodiment Construction

[0033] specific implementation plan

[0034] A method for enhancing and modifying palm rattan, comprising the following steps:

[0035] (1) Prepare the modified melamine urea-formaldehyde resin liquid for impregnation;

[0036] (2) Mixing the modified melamine urea-formaldehyde resin solution, water and additives to prepare the rattan impregnation modification treatment solution;

[0037] (3) Put the rattan material in the dipping modification treatment solution for dipping treatment, so that the rattan material can fully absorb the dipping modification treatment solution;

[0038] (4) Drying the impregnated rattan by a gradient drying method with gradually increasing temperature to obtain the modified rattan.

[0039] Take the enhanced modification of yellow rattan as a specific example: yellow rattan is a unique rattan species in my country, it is the main commercial palm rattan in China, and it is also one of the main rattan species artificially promoted and planted. Howeve...

Abstract

The invention belongs to a method for improving and modifying a palm rattan. The method comprises the steps that a modified melamine urea resin solution for impregnation is prepared; the modified melamine urea resin solution, water and an assistant are mixed; a rattan impregnated modified treatment solution is prepared; the rattan is placed in the impregnated modified treatment solution for impregnation treatment, so that the rattan sufficiently absorbs the impregnated modified treatment solution; the impregnated rattan is dried via a gradual temperature rise gradient drying method; and the modified rattan is obtained. With the adoption of the method, the strength and the stability of the rattan are improved, and the rattan has good toughness. The method has the advantages that the poor rattan can be optimized; the service life of the rattan can be prolonged; a use range of the rattan can be widened; an additional value of a rattan product can be increased; production is easy to control; equipment is simple; the production cycle is short; the cost is lower; the treated rattan can be widely applied to the industries of furniture, indoor decoration and the like; and an application prospect is wide.

Description

technical field [0001] The invention belongs to a method for enhancing and modifying palm rattan. Background technique [0002] Rattan is an important non-timber forest product second only to wood and bamboo. It has high economic value and ecological benefits. Rational development and utilization of palm rattan resources can prolong the performance and life of rattan and its products, optimize product structure and technology, and develop High value-added products are an important way for the development of my country's rattan industry. [0003] Under the condition of maintaining the natural ecological environment, the palm rattan forest can provide the same or even more use benefits than the forest, protect forest resources, and have good ecological benefits. Palm rattan has the characteristics of good strength, toughness, elasticity and easy shape. It is an excellent material for interior decoration, furniture production and craft utensils. It has strong decoration and pra...
