Abstract
The invention discloses a preparation method of a fast growing poplar modifying agent. The fast growing poplar modifying agent is synthesized by tripolycyanamide, formaldehyde, urea, carbinol, sodium hydroxide, water solution and hydrochloric acid, and the preparation method is implemented by eight process steps of A, B, C, D, E, F, G and H. The modifying agent is adopted for modifying fast growing trees, so that the performance of the trees are improved obviously, the woods and finished products of the woods have more effects such as damp resistance, cracking and deforming prevention, corrosion resistance, insect prevention, fire prevention and flaming retardance, the modified wood products can be on a pair with high-grade woods on the market in the aspects of strength, hardness, color, material, handfeeling, smell and the like, so that the additional value of the fast growing woods can be increased greatly, and the using range is enlarged, so that the incoming of a forestry operator is increased, the activity of the planting of the fast growing trees is improved, the development of ecological forestry and the building of new socialist countryside can be promoted.
Description
Technical field:
The present invention relates to a kind of preparation method for modifier of quick growth poplar wood material.
Background technology:
China carries forward vigorously the fast-growing, high-yield woods construction for increasing wood supply, but, fast-growing woods timber has rapidly effectively been alleviated the contradiction of China's timber supply and demand although grow, but material is loose, distortion easy to crack and the shortcoming such as corrosion resistant is not rotten, it is difficult on top-grade furniture and the woodwork, and can only be used in low-grade goods and wood-based plate manufacture view, the range of application of fast-growing woods timber and class all have been subject to very big restriction.
Summary of the invention:
The purpose of this invention is to provide a kind of fast-growing poplar preparation method for modifier;
The present invention adopts following technical scheme to realize its goal of the invention, a kind of fast-growing poplar preparation method for modifier, it is synthesized by melamine, formaldehyde, urea, methyl alcohol, NaOH, the aqueous solution, hydrochloric acid, and adopts A, B, C, D, E, F, eight processing steps of G, H to finish its preparation method; The proportioning of one kilogram of total amount of synthesis modification agent is: melamine: formaldehyde 2: urea: methyl alcohol: NaOH: the aqueous solution: hydrochloric acid=261.8g:389g:127.5g:165.4g:3.4g:12.2g:42.3g;
The A step is: melamine and formaldehyde are added in the there-necked flask;
The B step is: transfer PH to arrive with NaOH
9.2The about 0.9g of consumption; Approximately with 30 minutes) be warming up to
80About degree, reacted 40 minutes;
The C step is: be cooled to
70Degree (is used
3 ~ 5Minute), transfer pH value to arrive with the 40%NaOH aqueous solution
12More than (the about 12.2g of NaOH (40%) consumption);
The D step is: add urea 105g and methyl alcohol 165.4g; Reacted 60 minutes, and be cooled to about 65 degree;
The E step is: (approximately 38g) transfers about pH value to 9.2 with hydrochloric acid 10%;
The F step is: add urea 22.5g, dissolved 10 minutes;
The G step is: adding 10% hydrochloric acid (approximately 4.3g) accent pH value is 7.5, about 60 ~ 90 minutes of (30 minutes begin to survey water-soluble solution multiple, surveyed once in later per 10 minutes) reaction, and making the water extension rate is 5 o'clock, stops reaction;
The H step is: with 20%NaOH NaOH (the about 2.5g of consumption), transfer pH value to 10.5 ~ 11.0, cooling discharge.
Owing to adopted technique scheme, the present invention has realized its goal of the invention preferably, adopt modifier of the present invention that fast-growing woods timber is carried out modification, to the performance of timber itself be improved significantly, make timber and goods thereof possess more effect, such as protection against the tide, anti-craze and transfiguration, antiseptic insect-repelling, fire protection flame retarding etc., pass through simultaneously the Wooden modifying product of modification, its intensity, hardness, color, material, feel, smell etc. in addition can with market on high-grade timber compare favourably, this will improve the added value of fast-growing woods timber greatly, enlarge its scope of application, thereby Effective Raise forest management person's income and the enthusiasm of Planting Fast-growing trees, development and the building Socialist New of promotion ecological forestry.
The specific embodiment:
Below in conjunction with embodiment content of the present invention is described further.
