Problems solved by technology

Disadvantages and deficiencies: The treated wood unit may lose the liquid medicine during the dipping process, thus affecting the protective effect
Disadvantages and deficiencies: the protective agent and the adhesive do not have good compatibility, and cannot form a uniform and stable mixed phase, thus changing the performance of the adhesive and the protective agent
Disadvantages and deficiencies: If water-soluble preservatives are used for pressure treatment, it will cause excessive expansion in the thickness direction of the product and rough surface, resulting in loss of strength

Embodiment 1

[0033] raw material

[0034] Bamboo tow: 3 to 4 years old bamboo, straight and free of defects. After thawing, rolling, carbonization and other processes, it is made into bamboo tows with a length of 300mm, a width of 15-20mm, and a thickness of 2-4mm, which do not break in the transverse direction and are relatively loose in the longitudinal direction.

[0035] Adhesive: water-soluble phenolic resin, viscosity 60-110mPa·s (30°C); pH=9-11; solid content 47%, diluted with water to 25% solid content, ready for use.

[0036] Antifungal agent: agent A (organic iodine compound 3-iodo-2-propargyl butyl carbamate (IPBC), derived from Sanbo Biochemical Technology (Shanghai) Company), which is light yellow transparent liquid, water soluble Excellent sex. Preparation steps:

[0037] See figure 1 , the preparation method of recombinant bamboo in the present embodiment comprises the following steps:

[0038] 1) cut off: according to the format of the experimental mould, the bamboo to...

Embodiment 2-12

[0044] The preparation method of the recombinant bamboo of the embodiment of the present invention 2-12 is basically the same as embodiment 1, and difference is:

[0045] Embodiments 2 and 3 use different contents of drug A, and the contents are shown in Table 1 below.

[0046]Embodiment 4-6 uses different contents of medicament B (didecyldimethylammonium chloride (DDAC), derived from Sanbo Biochemical Technology (Shanghai) Co., Ltd.), which is a colorless transparent liquid and is easily soluble in water; implementation The specific content of the agent B used in Examples 4-6 is shown in Table 1 below, wherein the agent B is diluted to a concentration of about 1.5%.

[0047] Examples 7-9 use different contents of medicament C (IPBC+DDAC (1:1) compound), which is a water-soluble transparent liquid; the specific content of medicament C used in Examples 7-9 is shown in Table 1 below, where Agent C was diluted to a concentration of about 1.5%.

[0048] Embodiment 10-12 uses dif...

Abstract

The invention relates to a preparation method of recombinant bamboo. The preparation method comprises the following steps: cutting off a bamboo filament bundle into bamboo sections with the required length; applying an adhesive to the cut-off bamboo filament bundle and curing the adhesive; applying protective agents to the bamboo filament bundle, so that the protective agents are uniformly distributed on the surface of the bamboo filament bundle; drying the bamboo filament bundle; and paving the dry bamboo filament bundle into a plate blank and performing hot-press molding. The recombinant bamboo prepared by the method can synchronously realize flame-retardant, corrosion-resistant, mildew-proof and insect-preventing effects and has the characteristics of comprehensive distribution of pesticide effect, long residual period, high penetrability and the like.

Description

technical field [0001] The invention relates to a preparation method of recombined bamboo, in particular to a preparation method of recombined bamboo with anti-corrosion and anti-mildew properties. Background technique [0002] my country is the world's largest bamboo resource country. Bamboo has the characteristics of rapid growth and short rotation period. It has developed very rapidly in recent years and has become a pillar industry of forestry. The development of recombinant bamboo provides a new way for the efficient utilization of bamboo. [0003] Because bamboo itself contains a lot of starch, sugar, protein and other substances, it is easy to cause moths and rot, and it is easy to be attacked by mold and decay fungi in outdoor or indoor humid environments. Mildew affects the use value of products, causes economic losses, and endangers human health. When the amount of mold spores in the air reaches a certain amount, people will have allergic reactions, asthma and ot...
