FIELD: construction industry.
SUBSTANCE: invention refers to wood-working, furniture and construction industry. In order to develop non-toxic plate material, it is proposed to use moulding material from plant raw material without using synthetic binders. Moulding material in the form of plant raw material particles containing cellulose, lignine, easy- and difficult-to-hydrolyse polysaccharides and carboxyl groups is obtained by means of cavitation treatment of plant raw material; at that, it contains easy- and difficult-to-hydrolyse polysaccharides 13-18% and 28-37%, correspondingly, cellulose with copper index of 1.7-2.9 g/100 g - 53-58 %, lignine (Komarov) 31-37% and carboxyl groups 0.6-4.9 %.
EFFECT: cheap plate materials having high ecological and physic and mechanical properties are obtained from moulding material.
