Problems solved by technology

It has been found that a neutral composition containing water-soluble nitrogen-containing organic compounds, inorganic magnesium salts, boric acid, a small amount of emulsifier and penetrant is used to degrease and solidify pine wood. Non-toxic, low-viscosity polymer resin for degreasing, that is, after removing the flowable turpentine in the pine wood and fixing the rosin, re-inject a curable water-soluble resin, so that the treated pine wood can not only solve the problem of grease deformation, The strength and durability are also improved, and the wood has flame retardancy, which meets the flame retardancy requirements of fire protection for interior decoration materials

Abstract

A pine timber modification method is to eliminate its turpentine oil, fix its rosin and inject water-soluble resin capable of being cured. After deoiling and rosin fixing at 80-105 deg.C and under normal pressure for 3-10 hr, the pine timber is vacuum pumped for 0.5-1 hr, made to suck water-soluble fireproof polymer resin under 0.09-0.095 MPa vacuum and soaked for 1-5 hr under normal pressure. The deoiling and rosin fixing composition contains water-soluble nitogen-contained organic compound, magnesium, salt, boric acid, emulsifier, penetrant, and has pH value of 7.5-8.0. The pint timber thus processed has no rosin overflow and deformation, high strength and durability, and certain fireproof performance.

Description

technical field [0001] The invention relates to the modification of wood, especially the pollution-free modification method of pine wood, and also relates to the composition for modifying pine wood. Background technique [0002] Pine has the characteristics of fast growth and strong adaptability. It is a temperate tree species widely planted as economic forests in many forest farms and as income-generating forests in front of and behind houses in rural areas. However, due to the well-developed resin channels in the pine wood structure, the high content of turpentine, and the large deformation of the wood, it is easy to pollute the surface of the material with grease when the temperature is high, and can cause the paint layer to peel off, so the application is limited, usually only for building studs and Templates, packing box material use. [0003] In order to expand the utilization of pine wood resources, North America began to study the processing methods of pine wood in ...
