Embodiment 1

[0028] The adhesive for sheet material production of this embodiment includes: A agent and B agent, and the process preparation of A agent comprises the following steps:

[0029] 1. Add 1650 parts of phenol, 1000 parts of formaldehyde, 100-170 parts of ethylene glycol, and 150 parts of diethylene glycol at a time, and stir at room temperature for 30 minutes. Among them, diethylene glycol is added because diethylene glycol is flexible and stable against freezing effect;

[0030] 2. Slowly add hydrochloric acid and stir evenly to make the pH value 1;

[0031] 3. Slowly raise the temperature to 80°C, keep it warm at this temperature, measure the aldehyde content every half an hour, until the aldehyde content is 4% or below, lower it to 70°C, keep warm and vacuumize to obtain a light yellow viscous liquid ;

[0032] 4. Add 1900 parts of epichlorohydrin and reflux at 80°C for 30 minutes;

[0033] 5. Slowly drip 80% of the total amount of 1200 parts of sodium hydroxide within 2 h...

Embodiment 2

[0043] The adhesive used for the production of boards involved in this example includes: A agent and B agent, and the process preparation of A agent includes the following steps:

[0044] 1. Add 1500 parts of phenol, 900 parts of formaldehyde, 170 parts of ethylene glycol, and 130 parts of diethylene glycol at a time, and stir at room temperature for 30 minutes. Among them, adding diethylene glycol is because diethylene glycol has flexibility, antifreeze and other stabilizing effects;

[0045] 2. Slowly add hydrochloric acid and stir evenly to make the pH value 1;

[0046] 3. Slowly raise the temperature to 80°C, keep it warm at this temperature, measure the aldehyde content every half an hour, until the aldehyde content is 4% or below, lower it to 70°C, keep warm and vacuumize to obtain a light yellow viscous liquid ;

[0047] 4. Add 1800 parts of epichlorohydrin, reflux at 80°C for 30 minutes;

[0048] 5. Slowly drip 80% of the total amount of 1100 parts of sodium hydroxid...

Embodiment 3

[0058] A kind of adhesive for sheet material production that this example involves includes: A agent and B agent, and the technological preparation of A agent comprises the following steps:

[0059] 1. Add 1800 parts of phenol, 1100 parts of formaldehyde, 100 parts of ethylene glycol, and 170 parts of diethylene glycol at a time, and stir at room temperature for 30 minutes. Among them, adding diethylene glycol is because diethylene glycol has flexibility, antifreeze and other stabilizing effects;

[0060] 2. Slowly add hydrochloric acid and stir evenly to make the pH value 1;

[0061] 3. Slowly raise the temperature to 80°C, keep it warm at this temperature, measure the aldehyde content every half an hour, until the aldehyde content is 4% or below, lower it to 70°C, keep warm and vacuumize to obtain a light yellow viscous liquid ;

[0062] 4. Add 2000 parts of epichlorohydrin, reflux at 80°C for 30 minutes;

[0063] 5. Slowly drip 80% of the total amount of 1300 parts of sod...

Abstract

The invention relates to glue for producing a phenolic compact laminate plate and a phenolic compact laminate plate production method using the same. The glue comprises an agent A and an agent B. The agent A comprises 900-1100 parts of formaldehyde, 1500-1800 parts of phenol, 1800-2000 parts of epichlorohydrin, 90-110 parts of a coupling agent, 130-170 parts of diethylene glycol, and 25 -35 parts of tert-butyl peroxybenzoate. The glue has the advantages of good flexibility, anti-freezing stability, bonding fastness and short compression cycle.

Description

technical field [0001] The present invention relates to an adhesive for board production and a method for producing a Combeite board using the adhesive, in particular to a production method for a Combeite board with good stability, firm handover and short gluing and pressing cycle. Adhesives belong to the field of using adhesives to produce boards. Background technique [0002] In the field of adhesives, in the late 20th century, developed countries in the world, such as Fushilan Corporation of the United States, developed a polymer composite adhesive based on polymer materials and composite material technology. A two-component or multi-component composite material composed of molecular composite polymer and metal powder or ceramic particles, it can greatly solve and make up for the application weakness of metal materials, and can be widely used in wear, erosion, corrosion, seepage of equipment parts Leakage, cracks, scratches and other repair protection. [0003] Among al...
