Abstract

The invention discloses a production method of reinforced flame retardation wood. The method comprises the following steps: 1, weighing 20-40mass% of guanylurea phosphate, 5-25mass% of diammonium phosphate, 5-15mass% of zinc borate, 5-15mass% of potassium dichromate, 5-25mass% of dichloromethane, 3-8mass% of aluminum sulfate, 3-8mass% of sodium molybdate, 0.5-3mass% of diethanolamine and 0.1-1mass% of pentaerythritol; and 2, adding above components into a reaction kettle, uniformly mixing, adding water to prepare a solution, and carrying out a heating reaction. The production method has the advantages of simplicity, easy industrialization, clean and pollution-free production, low cost and convenient operation, and the material obtained in the invention allows processed wood to have good mildew and moth resistance and good flame retardation effect reaching nonflammable grade in the wood vacuum pressurizing impregnating treatment.

Description

The production method of a kind of enhancing, fire retarding wood

Technical field

The present invention relates to timber treatment technology field, specifically the production method of a kind of enhancing, fire retarding wood.

Background technology

China's artificial forest area ranks first in the world, at present more than 0.53 hundred million hectare, mainly contain willow, China fir, masson pine, eucalyptus etc., the ubiquitous material of these timber be soft, density is low, distortion is large, the weakness such as poor processability, limit their application in some aspects.Strengthen closely knit process by timber can solve the problem; Simultaneously timber belongs to combustible material, and easily rotten and deform, and therefore, timber is also needed to give to the process of the aspect such as fire-retardant, anticorrosion, this to imparting timber New function, widen timber new opplication field and have important practical significance.

Summary of the invention

The object of the present invention is to provide the production method of a kind of low cost, enhancing easy to use, fire retarding wood.

The technical solution adopted for the present invention to solve the technical problems is: the production method of a kind of enhancing, fire retarding wood, comprises the steps:

(1), following ingredients is taken by mass percent proportioning:

Guanyl-urea-phosphate 20% ~ 40%;

Diammonium hydrogen phosphate 5% ~ 25%;

Firebrake ZB 5% ~ 15%;

Potassium bichromate 5% ~ 15%;

Carrene 5% ~ 25%;

Aluminum sulfate 3% ~ 8%;

Sodium molybdate 3% ~ 8%;

Diethanol amine 0.5% ~ 3%;

Pentaerythrite 0.1% ~ 1%;

(2), by above-mentioned each component add in reaction Fu and carry out Homogeneous phase mixing, and add water that to be made into mass concentration be 15% ~ 35% solution, to be then heated at 70 DEG C ~ 90 DEG C temperature reaction 0.5 ~ 4 hour, to be cooled to room temperature, namely to complete the present invention.

The invention has the beneficial effects as follows, compared with prior art, production method provided by the invention is simply easy to industrialization and cleanliness without any pollution is produced, cost is lower, easy to operate, the material obtained by the present invention, during for the process of wood vacuum impregnating by pressure, the timber of process can be made to have mildew-resistant, mothproof and good flame retardant effect, anti-flammability reaches difficult combustion rank (oxygen index (OI) > 45%), and rate of body weight gain is 10% ~ 15%, anti-swollen rate reaches 30% ~ 50%, and elastic modelling quantity and bending strength improve more than 20% and 35% respectively.

Detailed description of the invention

Technical scheme of the present invention is further illustrated below in conjunction with concrete preferred embodiment.

A production method for enhancing, fire retarding wood, comprises the steps: (1), takes following ingredients by mass percent proportioning: guanyl-urea-phosphate 30%, diammonium hydrogen phosphate 15%, Firebrake ZB 15%, potassium bichromate 15%, carrene 10%, aluminum sulfate 6%, sodium molybdate 5%, diethanol amine 3%, pentaerythrite 1%; (2), by above-mentioned each component add in reaction Fu and carry out Homogeneous phase mixing, and add water that to be made into mass concentration be 15% ~ 35% solution, to be then heated at 70 DEG C ~ 90 DEG C temperature reaction 0.5 ~ 4 hour, to be cooled to room temperature, namely to complete the present invention.
