    4 The invention relates to boric anhydride based solutions used as curing agents for resole phenol formaldehyde resins. A known curing agent for phenol-formaldehyde resins, including boric anhydride and hexamethylenetetramine. 3 However, the polymer pressing capacity, including this hardener, will have a low cure rate. Closest to the proposed technical essence and the achieved result is a hardener for rezol phenol-formaldehyde resins, including boric anhydride. Boric anhydride is introduced into the press in the form of a powder; therefore, the use of a hardener is associated with technological difficulties arising from the simultaneous introduction into the form of liquid and solid components included in a polymer press composition. In addition, the disadvantage of the known hardener is the need for accurate dosing of solid components, namely boric anhydride. The purpose of the invention is to simplify and speed up the preparation process {| polymeric press composition. This goal is achieved by the fact that the hardener for phenolic resins phenol-formaldehyde resins, including boric anhydride, contains an acidic component selected from the group: sulfuric acid, Vl-toluenesulfonic acid, a mixture of sulfuric and I-toluenesulfur acids at a weight ratio of 5 - 3, and an organic solvent selected from the group: trimethylborate, methylal, methanol, with the following ratio of components, weight .; Boric anhydride 10.6-27.3 Acidic componentM, 3-42, i Organic solvent Else The hardener is prepared according to the following technology. Boric anhydride in powder form is added with stirring at rooms. temperature in a variety of solvents, including a mixture of the acid component and an organic solvent. The prepared hardener is a clear solution. The solubility of boric anhydride in sulfuric acid, in organic solvents, e.g. methylal, methanol, ethanol, dipropyleneglycol and trimethyl borate, as well as in a mixture of organic solvents, e.g. five%. Therefore, the listed solvents are not used separately for the preparation of the proposed hardener. To increase the solubility of boric anhydride, a mixture of the acid component with organic solvents is used as a solvent. The data on the solubility of boric anhydride at room temperature in a mixture of the acid component with organic solvents are given in Table. 1. The compositions used as a hardener for resole phenol-formaldehyde resins are listed in Table 2. As rezol phenol-formaldehyde resin use resols, which are obtained by condensation of phenol and formaldehyde in the presence of caustic soda, followed by. By neutralizing the resulting product to pH 7 and drying in vacuo to obtain the desired viscosity. The conditions for the condensation of the resols are given in table. 3. Resol P is used in pure form; the R / 2 resol is diluted with methanol (5 parts of methanol per 100 parts of the resol) to obtain a product that has 8 P bones at 20 ° C, termed R; Resol R.-5 is diluted with dipropylene glycol (12 parts per 100 parts of Resol) to obtain a product having a C-. Bone 15 P at 20 ° C, named R, given in Table. 3 amounts of dry extract are obtained by drying g of the corresponding resole for 3 hours at C. Different resols are mixed with hardening agent solutions according to the examples in the table. 2. The mixture is kept at and measured during its existence in the form at the indicated temperature (Table 4). Resole R-ij together with hardener according to the table. 2 can be used to teach glass fiber reinforced laminates to be made by simultaneous insertion.
    components using the method of injection or impregnation. In all cases, the resulting products. you have good homogeneity and surface finish.
    Thus, the selection and ratio of components in the proposed hardener allows one to think over solutions with a high concentration of boric anhydride, which accelerates and simplifies the process of preparing a polymeric press composition based on rezol phenol-formaldehyde resin at a very high curing rate. ,four.
