Problems solved by technology

[0004] The purpose of the present invention is to provide a kind of glue formula for plywood production in view of the existing problems, which solves the problem that formaldehyde is usually contained in the traditional glue proposed in the above-mentioned background technology, which does not have environmental protection and will cause pollution, and the glue is not stable. The viscosity is not very efficient. With the increase of time, the glue is easy to lose its viscosity. Environmental protection and the production cost of glue with good viscosity are relatively high.

Embodiment 1

[0013] 33 parts of acrylic resin, 8 parts of polyimide, 12 parts of styrene-acrylic water-based resin emulsion, 14 parts of polyethylene glycol, 12 parts of polyester fiber, 11 parts of antioxidant, 11 parts of emulsifier, 15 parts of mold inhibitor, 9 parts of stabilizer, 5 parts of amino resin, and 7 parts of sodium hydroxide. At this time, the glue has a certain viscosity, but the environmental protection is not very ideal, and there is a certain amount of pollution.

Embodiment 2

[0015] 31 parts of acrylic resin, 5 parts of polyimide, 11 parts of styrene-acrylic water-based resin emulsion, 10 parts of polyethylene glycol, 9 parts of polyester fiber, 8 parts of antioxidant, 11 parts of emulsifier, 13 parts of mold inhibitor, 7 parts of stabilizer, 5 parts of amino resin, and 3 parts of sodium hydroxide. At this time, the glue has certain environmental protection, but the viscosity of the glue is not very ideal.

Embodiment 3

[0017] 34 parts of acrylic resin, 6 parts of polyimide, 11 parts of styrene-acrylic water-based resin emulsion, 12 parts of polyethylene glycol, 9 parts of polyester fiber, 10 parts of antioxidant, 11 parts of emulsifier, 13 parts of mold inhibitor, 9 parts of stabilizer, 2 parts of amino resin, and 6 parts of sodium hydroxide. At this time, the glue has high cohesiveness and excellent environmental protection.

Abstract

The invention discloses a glue formula for plywood production, which comprises the following components: acrylic resin, polyimide, styrene-acrylic water-based resin emulsion, polyethylene glycol, polyester fiber, an antioxidant, an emulsifier, a mildew preventive, a stabilizer, amino resin and sodium hydroxide. The glue formula for plywood production has the beneficial effects that the glue for plywood production has efficient environment friendliness and is free of pollution, the viscosity of the glue is good, and the manufacturing cost is low.

Description

technical field [0001] The invention relates to the related technical field of glue formula, in particular to a glue formula for plywood production. Background technique [0002] Plywood is one of the commonly used materials for furniture, and it is one of the three major boards of wood-based panels. It can also be used for aircraft, ships, trains, automobiles, buildings and packaging boxes. A group of veneers are usually assembled and glued together according to the direction of the wood grain of adjacent layers perpendicular to each other. Usually, the surface board and inner layer board are symmetrically arranged on both sides of the center layer or core. The slab made of the veneer after gluing is criss-crossed according to the direction of wood grain, and pressed under heating or non-heating conditions. The number of layers is generally an odd number, and a few have even numbers. The difference in physical and mechanical properties in the vertical and horizontal direc...
