Abstract: In order to obtain a better breathing impregnation technology, the influence of technological parameters on the impregnation effect of silicate modified Chinese fir was discussed. In addition, the fire resistance of the modified Chinese fir was explored to provide technical support for expanding the application scope of Chinese fir and increasing the added value of products. The silicates impregnated modified Chinese fir was prepared by respiration method, in which the silicates were used as the impregnating modifier. The breathing impregnation process was optimized by single factor experiment and response surface method, and the fire resistance of modified Chinese fir was tested by butane gun combustion and cone calorimeter (CONE). Response surface analysis showed that the influence of each process factor on the weight percentage gain was impregnation pressure > sodium silicate concentration > impregnation time > breathing times. The optimum impregnation process was 31.60% of sodium silicate solution concentration, 3.80 h of impregnation time, 0.7 MPa of impregnation pressure and 6 times of breathing times. The combustion experiments showed that the flame of modified fir was small. The results of CONE showed that HRR, THR, SPR and TSP of the modified Chinese fir were significantly lower than those of the unmodified Chinese fir, and the residual carbon structure was relatively complete.
