Problems solved by technology

However, there are two problems with the use of repairing agent to finish and then manual repair: 1. The efficiency of manual repair is not high, especially for the surface plate with low repair level. The workload of manual repair is large, which reduces the production efficiency; 2. The repair agent is not firmly bonded to the surrounding wood, especially to the surrounding knots.
Existing repairing methods are wasteful and the repairing effect is not good

Embodiment 1

[0026] The repair agent uses Shanghai Resin Factory Lubao brand 618 epoxy resin and Lubao brand 5618 epoxy resin curing agent. It is prepared according to the weight ratio of 100:50. When preparing, first pour 100g of epoxy resin into a disposable plastic cup , then add 50g of curing agent and stir evenly, add 2g of black essence and mix evenly, dip it with a wooden stick and drop it on the knots. After repairing, the floors are separated by spacers with an average thickness of about 9mm, 10-12h After the epoxy resin is cured, the prepared repair agent is cured in the cup for 20-40 minutes.

Embodiment 2

[0028]The repair agent adopts Shanghai Resin Factory Lubao brand 618 epoxy resin and Lubao brand 5618 epoxy resin curing agent. It is prepared according to the weight ratio of 100:65. When preparing, first pour 100g of epoxy resin into a disposable plastic cup , then add 65g of curing agent and stir evenly, add 0.5g of black essence and mix evenly, dip it with a wooden stick and drop it on the knots. After repairing, separate the floors with spacers with an average thickness of about 9mm, After 12 hours, the epoxy resin is cured, and the prepared repair agent is cured after 20-40 minutes in the cup.

Embodiment 3

[0030] The repair agent uses Shanghai Resin Factory Lubao brand 618 epoxy resin and Lubao brand 5618 epoxy resin curing agent. It is prepared according to the weight ratio of 100:50. When preparing, first pour 100g of epoxy resin into a disposable plastic cup , then add 50g of curing agent and stir evenly, add 20g of wood powder to mix evenly, dip it with a wooden stick and drop it on the knots, and after repairing, separate the floors with spacers with an average thickness of about 9mm, 10-12h After the epoxy resin is cured, the prepared repair agent is cured in the cup for 20-40 minutes.

Abstract

The invention belongs to the technical field of chemical adhesives, and relates to a wood floor repairing agent and a using method thereof. The wood floor repairing agent is prepared by compounding and blending epoxy resin and an epoxy resin curing agent, wherein the epoxy resin is bisphenol A-type epoxy chloropropane with low molecular weight; the epoxy resin curing agent is polyethylenimine, wherein the weight ratio of the epoxy resin to the epoxy resin curing agent is 100: (50-70). The invention further discloses the using method of the repairing agent. By adopting the wood floor repairing agent disclosed by the invention, the efficiency of manual repair of a solid wood composite floor can be improved, and when the veneer floor with low repair grade is repaired, compared with the repairing efficiency of the quick-drying putty, the efficiency is improved by about 100%; the repairing agent is firmly adhered to the surrounding wood, cracking and detachment between the repairing agent with knots and the wood are avoided, and the detection requirements of 6.2.5 surface hot-cold cycle resistant test in the standard LY / T1700-2007 of wood based flooring for ground with a heating system can be met. The improvement of the repairing quality of the material species rich in the medullary spot and resin pocket is more obvious, and the repairing agent has a good application prospect.

Description

technical field [0001] The invention belongs to the technical field of chemical adhesives, and relates to a floor repair agent, in particular to a wooden floor repair agent and a use method. Background technique [0002] The surface of the three-layer solid wood composite floor generally uses 3-4mm hard wood species as the surface board, and the cork veneer used for the core board and the bottom board is mostly fast-growing wood such as spruce, sylvestris pine, poplar, and eucalyptus. The hard wood used to make the panel generally has natural or post-processing defects such as knots and cracks. Knots include dead knots, leaky knots, and cracked joints. Cracks include closed cracks and open cracks. Completely eliminating these wood defects will greatly reduce the utilization rate of wood. In the current situation of increasingly tight natural wood resources, it is necessary to Study how to make good use of limited wood resources efficiently. [0003] At present, there are g...
