Problems solved by technology

[0003] Since particleboard is a wooden product, if it is not kept ventilated in a rainy day, it is easy to be deformed due to air humidity, and even moldy and rotten, resulting in a serious musty smell in the room, and most of the particleboards are made of particleboard through adhesives. After a long time of moisture absorption, the board will be warped and deformed due to the difference in expansion force, which will seriously affect the needs of particleboard for production and life, thereby affecting its market promotion and application.

Embodiment 1

[0023] (1) Preparation of epoxy soybean oil modified polyamine curing agent: first put 5mol of hydroxyethylethylenediamine in a container, heat to 100°C under nitrogen protection, then add 1mol of epoxy soybean oil (epoxy value 4.03 ) slowly dropwise into the container containing hydroxyethylethylenediamine. After the dropwise addition, the temperature was raised to 110° C., and the reaction was terminated after keeping the temperature for 4 hours to obtain a brown-yellow viscous liquid.

[0024] (2) Weigh raw materials: 100 parts of shavings, 35 parts of rice husk, 10 parts of epoxy resin, 10 parts of epoxy soybean oil modified polyamine curing agent, 3 parts of preservative (pentachlorophenol);

[0025] (3) After drying the shavings with a moisture content of 4%, they are evenly mixed with preservatives and rice husk powder crushed through a 300-mesh sieve, and then divided into two equal parts, which are evenly mixed with epoxy resin and curing agent respectively. , mixed ...

Embodiment 2

[0027] With embodiment 1, difference is that step (2) takes by weighing raw materials: 70 parts of shavings, 20 parts of rice husks, 5 parts of epoxy resins, 5 parts of epoxy soybean oil modified polyamine curing agents, preservative (pentachlorophenol )3 copies.

Embodiment 3

[0029] With embodiment 1, difference is that step (2) takes by weighing raw materials: 85 parts of shavings, 30 parts of rice husks, 8 parts of epoxy resins, 8 parts of epoxy soybean oil modified polyamine curing agents, preservative (pentachlorophenol ) 5 copies.

Abstract

The invention discloses an anticorrosive shaving board and a preparation method thereof. The anticorrosive shaving board is prepared from shavings, rice husks, epoxy resin, a curing agent and a preservative. The preparation method comprises the following steps of uniformly mixing the shavings, the preservative and the crushed and sieved rice husks, dividing the mixture into two equal parts, uniformly mixing the two parts with the curing agent and the epoxy resin respectively, uniformly mixing the mixture of the shavings mixed with the curing agent and the epoxy resin again, paving the mixturein mold ore, and carrying out hot press molding to obtain the anticorrosive shaving board. The rice husks are added into the raw materials, the epoxy resin is used as an adhesive of the shaving board,and the anticorrosive shaving board which is environmentally friendly, non-toxic, good in waterproofness and stable in performance is provided.

Description

technical field [0001] The invention relates to the technical field of wood processing, in particular to an antiseptic particleboard and a preparation method thereof. Background technique [0002] Particleboard is also called particle board, which cuts various branches, small-diameter wood, fast-growing wood, sawdust, etc. A kind of artificial board. [0003] Since particleboard is a wooden product, if it is not kept ventilated in a rainy day, it is easy to be deformed due to air humidity, and even moldy and rotten, resulting in a serious musty smell in the room, and most of the particleboards are made of particleboard through adhesives. After a long time of moisture absorption, the board will warp and deform due to the difference in expansion force, which will seriously affect the needs of particleboard for production and life, thereby affecting its market promotion and application. Contents of the invention [0004] In order to solve the above-mentioned technical probl...
