Abstract: A compression-molding composition contains a phenol-formaldehyde resin, a filler, a curing agent, viz. hexamethylenetetramine, a curing accelerator such as calcium oxide or magnesium oxide, and a lubricant such as stearin or stearates. The filler comprises a product resulting from the treatment of crushed wood with an aqueous solution of phenol and formaldehyde at the boiling temperature of said solution in the presence of hydrochloric acid at a weight ratio between phenol, formaldehyde, water, hydrochloric acid, crushed wood equal to 0.15-0.80:0.045-0.864:6-15:0.0435-0.1086:1 respectively. Proportions of the components are as follows, parts by weight:______________________________________ phenol-formaldehyde resin 15 to 45 filler 47.5 to 75 curing agent 7 to 9 curing accelerator 0.5 to 1 lubricant 0.6 to 0.9 ______________________________________The compression-molding composition according to the present invention has an increased water-resistance (17 to 19 mg), heat-resistance (up to 182.degree. C.

Abstract: The compression-moulding composition according to the present invention contains 95 to 98 parts by weight of a product resulting from the treatment of crushed wood with an aqueous solution of phenol and formaldehyde at the boiling temperature of said solution in the presence of hydrochloric acid at a weight ratio between phenol formaldehyde, water, hydrochloric acid and crushed wood equal to 0.15-0.40:0.048-0.27:10-15:0.0724-0.1086:1 respectively, 1 to 3 parts by weight of a curing agent, viz. hexamethylenetetramine, 0.5 to 1 part by weight of a curing accelerator such as calcium oxide or magnesium oxide and 0.5 to 1.0 part by weight of a lubricant such as stearing, oleic acid or stearates. The compression-moulding composition of the present invention has an increased water-resistance (its water-absorption is at most 42-82 mg), a high curing rate (0.57-0.8 min/mm), elevated Martens yield temperature (up to 146.degree. C.
