[0046] Embodiment 1-5 is used to illustrate the preparation method of raw gum in straw hat gum, specifically comprises the steps:

[0047] Step 1: Put the raw gum in a container with ethanol and stir;

[0048] Step 2: Add polyvinyl butyral evenly to the ethanol for raw gum while the ethanol for raw gum is in a stirring state, and control the adding time of polyvinyl butyral to 25-35 minutes;

[0049] Step 3: Continue to stir for 4-8 hours, and stop stirring when the raw gum is clear, transparent or slightly yellow;

[0050] Step 4: Seal the raw glue for 12-24 hours and set aside.

Abstract

The invention discloses straw hat glue and a preparation method thereof. The straw hat glue comprises the following components in parts by weight: 5-10 parts of raw glue, 1-3 parts of a stiffening agent, 18-20 parts of ethanol for the straw hat glue and 0.1-0.3 part of ethylene glycol monobutyl ether; the raw glue comprises polyvinyl butyral and ethanol for the raw glue; the mixing weight ratio ofthe polyvinyl butyral to the ethanol for the raw glue is 1 to 8-10; the stiffening agent comprises modified polyvinyl butyral and ethanol for the stiffening agent; the mixing weight ratio of the polyvinyl butyral and ethanol for the stiffening agent is 1 to 8-10. The straw hat glue has the beneficial effects as follows: the straw hat glue can shape a straw hat to improve the hardness and the aesthetic degree of the straw hat, and has the characteristics of no toxicity and environment friendliness, so that the body damage to gluing personnel is reduced.

Description

technical field [0001] The invention relates to glue, in particular to a straw hat glue and a preparation method thereof. Background technique [0002] Straw hats generally refer to hats woven with water grass, mat grass, wheat straw, bamboo strips or brown rope. The brim of the straw hat is relatively wide, which can be used to protect from rain and sun. During the preparation process of the straw hat, the straw hat needs to be dipped into the straw hat glue to carry out the shaping of the straw hat, so as to increase the hardness and aesthetics of the straw hat. [0003] The existing straw hat glue generally includes the following components in parts by weight: 0.3-0.7 parts of toluene and 0.03-0.15 parts of polyvinyl butyral. However, when the straw hat is dipped into the straw hat glue to shape the straw hat, the sizing personnel will inevitably inhale toluene, causing the sizing personnel's body to be harmed by toluene. Therefore, how to provide a kind of effect simi...
