Problems solved by technology

Among them, "trialdehyde glue" is cheap, but formaldehyde is easy to exceed the standard; white latex has poor water resistance; styrene-acrylic emulsion and pure acrylic emulsion have insufficient boiling resistance
In addition, because they all contain moisture, it is easy to cause wood to absorb water and curl; studies have found that epoxy resins have strong adhesion to wood and good heat resistance, but ordinary bisphenol A epoxy resins have too high crosslinking density and the film is hard and brittle , and has certain reproductive toxicity

Embodiment 1

[0092] The present embodiment prepares a kind of epoxy resin jigsaw glue, and the specific process is:

[0093] D1. Preparation of epoxy castor oil:

[0094] Add 80 parts of water into the round-bottomed flask, turn on the mixer, add 9.54 parts of sodium bicarbonate and 2.85 parts of tetrabutylammonium bromide in turn, stir for 10 minutes, then add 134 parts of castor oil, and after stirring for 30 minutes, control the temperature of the water bath to be 50 ℃, 142.5 parts of 30% acetic acid was added dropwise for 3 hours, and the temperature was kept for 3 hours; after standing for 24 hours, the supernatant was taken out, and then subjected to vacuum distillation. The temperature of vacuum distillation was 60℃ and the pressure was 0.02MPa. The remaining pale yellow liquid is epoxy castor oil; the preparation technique of this step is as follows figure 1 shown.

[0095] D2. Preparation of component A:

[0096] In parts by weight, take 100 parts of epoxy castor oil prepared i...

Abstract

The invention discloses an epoxy resin plate splicing adhesive and a preparation method and application thereof. The epoxy resin plate splicing adhesive is prepared from a component A and a component B. The component A is prepared from epoxy castor oil, a defoaming agent, a dispersing agent, filler and a thixotropic agent; and the component B is prepared from a curing agent. The epoxy resin plate splicing glue prepared by the invention has the advantages of high flexibility, weather resistance and boiling resistance, low VOC content and the like.

Description

technical field [0001] The invention belongs to the technical field of adhesives, and in particular relates to an epoxy resin panel glue and a preparation method and application thereof. Background technique [0002] With the development of the economy, people's demand for wooden furniture has gradually increased from focusing on appearance to focusing on material. Glulam is made of short and small materials or small-diameter materials, which not only retains the excellent characteristics of natural wood material uniformity, but also can Splicing to form large-sized panels that cannot be replaced by wood-based panels, greatly improves the utilization rate of wood, and is generally welcomed by the market. Panel glue refers to the adhesive used for splicing wood products such as lamellae, and is suitable for panel bonding of non-structural materials and lamellae for structural materials. The main components of the early solid wood plywood glue are neoprene, bone glue, cowhide...
