Embodiment Construction

[0038] The preferred embodiments of the invention will be further described in detail below.

[0039] The manufacturing method of the phenolic resin glue that is used for bamboo-wood integrated profile of an embodiment, comprises the steps:

[0040] (1) Take 40-60 parts of formaldehyde (mass parts, the same below), 30-50 parts of phenol, 5-8 parts of sodium hydroxide (liquid caustic soda or caustic soda) (mixed with water 1:1.5-3), diethyl 1 to 5 parts of diol and 0.5 to 5 parts of iron dioxide (mixed with water 1:20 to 50, that is, iron dioxide: water is 1:20 to 50 (ratio of parts by mass)), and then add the above mixture to the reactor After stirring evenly, adjust the pH value of the mixture to 7-8 by adding liquid caustic soda or caustic soda, then raise the temperature to 65-85°C, and then keep it warm for 50-90 minutes, and keep the temperature within the range of 65-85°C.

[0041] (2) After 50-90 minutes of heat preservation, after the temperature drops to 45-60°C, tes...

Abstract

The invention discloses a manufacture method used for a bamboo and wood integration section bar. The manufacture method comprises the following steps of crushing a bamboo chip from which bamboo green, a bamboo inner skin and bamboo joints are removed into a gauze shape; putting the gauze-shaped bamboo chip into a capped container for boiling, wherein the capped container contains hydrogen peroxide aqueous; putting the boiled gauze-shaped bamboo chip into a carbonization furnace for carbonization; carrying out drying processing on the carbonized gauze-shaped bamboo chip; adding phenolic resin glue on the gauze-shaped bamboo chip subjected to the drying processing; drying the gauze-shaped bamboo chip with the phenolic resin glue; putting the dried gauze-shaped bamboo chip into a die for carrying out compression moulding, and carrying out thermocuring when the temperature is kept at 150-200DEGC to obtain the bamboo and wood integration section bar; cooling and demolding the bamboo and wood integration section bar. When being used as outdoor materials, the bamboo and wood integration section bar disclosed by the invention is free from soaking, swelling, cracking, deforming, rotting or being damaged by worms, and a semi-porcelain effect can be achieved.

Description

【Technical field】 [0001] The invention relates to the field of glue for bamboo and wood integrated profiles, in particular to a method for manufacturing phenolic resin glue for bamboo and wood integrated profiles. 【Background technique】 [0002] With the development and progress of society and the continuous improvement of people's living standards, people pay more and more attention to indoor decoration. Generally, people use natural green environmental protection materials for decoration. Rich people not only pay attention to interior decoration materials, but also pay attention to outdoor gardens. Landscape construction is also becoming more and more particular. But at present, the world's precious and high-quality wood is banned and scarce, and the demand for natural wood for outdoor buildings in my country and the world is increasing. Outdoor decorative wood can only use artificial anti-corrosion wood that cannot withstand the corrosion of the four seasons. The low-grad...
