Abstract

The present invention aims to provide a wood template restoration agent, its composition and weight percentage are as follows: epoxy resin 18%-47%, diluent 10%-15%, lignin 20%-30%, wood carbon powder 20%- 30%, quartz powder 2%‑5%, pigment 1%‑2%. Also provide the preparation method of the repairing agent: A, adding 10-15% diluent by weight into epoxy resin with 18%-47% by weight, stirring; B, taking lignin and charcoal for grinding Pressing, screening, getting the lignin of 20%-30% by weight and wood charcoal powder of 20%-30% by weight to add the above-mentioned mixture; C, adding the quartz powder and the weight percentage of 2%-5% Stir after adding 1%‑2% pigment. The invention also provides a method for using the restoration agent. The wood formwork restoration agent provided by the invention has strong adhesion and good gluing performance, and can effectively repair formwork wounds.

Description

technical field [0001] The invention relates to the field of wood treatment, in particular to a wood template restoration agent and its preparation and use methods. Background technique [0002] At present, high-end buildings, bridges, viaducts, tunnels, and culverts need to use film-coated panels with clear water film on the surface. The surface of clear-water film-coated panels is smooth and flat, and the concrete surface does not need to be scraped and trimmed again; but The film-coated board is made of wood, and the environment of the construction site is relatively poor. It is inevitable that the film-coated board will be damaged by being smashed, bumped, or scratched. Once the fair-faced formwork is damaged, it cannot be used as a formwork for fair-faced concrete, but can only be used as a general formwork, and the price of the clear-water film-coated board is about 35% higher than that of a general formwork, which causes unnecessary waste. [0003] In addition, other...
