Problems solved by technology

[0002] Common eyeglass frames on the market are usually made of metal or plastic. In order to reduce their own weight, eyeglass frames made of metal are usually made of titanium alloy and other materials, which are relatively expensive and expensive, while plastic Spectacle frames are prone to damage due to the brittleness of the plastic and are not durable
In order to improve modern life and market needs, some spectacle frames made of bamboo and wood have also appeared on the market. Bamboo and wood spectacle frames are popular because of their environmentally friendly materials, light weight, and stylish appearance. The splicing method is combined into an integrated structure. The splicing points often need to be glued and fixed. Bamboo and wood spectacle frames are often exposed to water or sweat during use. Ordinary wood adhesives are not resistant to moisture. After a long time of use, the adhesive It is easy to age, and the colloid in the seams of bamboo and wood glasses frames is easy to mold and breed bacteria, which will have a certain impact on the eyes. Therefore, we have proposed a kind of adhesive glue for bamboo and wood glasses and its preparation method

Abstract

The invention discloses an adhesive for bamboo glasses. The adhesive comprises the following raw materials in parts by weight: 65 to 85 parts of vinyl acetate; 15-45 parts of an emulsion stabilizer, 35-55 parts of natural latex, 3-10 parts of cellulose acetate butyrate, 5-15 parts of butyl acetate, 0.1-0.8 part of an initiator, 1-5 parts of a plasticizer, 0.1-0.5 part of an emulsifier, 1-4 parts of an anti-aging agent, 0.5-1.5 parts of a mildew preventive, 2-5 parts of a water repellent and 10-15 parts of a filler. The invention further provides a preparation method of the adhesive for the bamboo glasses. The adhesive not only has the effect of delaying aging, but also has the advantages of acid and alkali resistance, moisture resistance, mildew resistance, capability of inhibiting breeding of germs and mites, good hydrophobicity, moisture resistance, ultraviolet light resistance and cold resistance, and meets the requirements of people nowadays.

Description

technical field [0001] The invention relates to the technical field of bamboo wood processing adhesives, in particular to an adhesive glue for bamboo wood glasses and a preparation method thereof. Background technique [0002] Common spectacle frames on the market are usually made of metal or plastic. Spectacle frames made of metal are usually made of titanium alloy and other materials in order to reduce their own weight. High-quality spectacle frames are prone to damage due to the brittleness of the plastic and are not durable. In order to improve modern life and market needs, some spectacle frames made of bamboo and wood have also appeared on the market. Bamboo and wood spectacle frames are popular because of their environmentally friendly materials, light weight, and stylish appearance. The splicing method is combined into an integrated structure.
