Abstract
The present invention relates to a kind of phenol resin glue and manufacture method thereof, according to the Resin adhesive that this method is made, technology is simple, easily grasp, and molten water-based is very strong, good dispersity, can adapt to different size applicators and use.Can be used for bonding between material of construction such as rock wool according to different water solubilizations, help increasing intensity by sticky object.The proportioning raw materials and the processing parameter that the present invention is characterized in this glue.
Description
The present invention relates to a kind of phenol resin glue and production method thereof, it is made up of phenol, formaldehyde, hydrated barta.
In the prior art, phenol: formaldehyde: the hydrated barta proportioning is 1: 0.36: the 2.06(weight ratio).This Phenol aldehyde resin charge temperature and temperature of reaction height, 65～70 ℃ of charge temperatures, 85～100 ℃ of temperature of reaction, the phenolic glue that obtains with this proportioning and processing parameter, molecular chain is big, viscosity is big, bad dispersibility, molten water-based are poor, the water solubilization of this glue must not be greater than 20%, if precipitation and muddy phenomenon will occur, the cementability of reduction glue greater than 20%.In addition, this phenolic glue price is expensive.Can only be used for the macropore size applicator.(China Forest press " Wood-based Panel Production handbook volume two)
The object of the present invention is to provide a kind of good dispersity, Phenol aldehyde resin that molten water-based is very strong and manufacture method.
This glue provided by the present invention is to use phenol: formaldehyde: hydrated barta=1: 0.6～1: 0.03～0.06(weight ratio) proportioning raw materials, and control through following processing parameter and to finish.Be charge temperature at 43～55 ℃, reinforced 7～20 minutes time, material all adds 90～130 minutes afterreaction time, temperature range is at 40～76 ℃.Wherein, temperature is controlled between 43～48 ℃ when adding hydrated barta, and the time is controlled in 10～20 minutes to best.In addition, after adding hydrated barta, adding the preceding temperature of formaldehyde should react 25～35 minutes between 40～55 ℃.Viscosimetric under above-mentioned condition control when viscosity reaches requirement, is cooled to 30～40 ℃ of blowings, promptly obtains product.
The present invention compared with prior art has following advantage:
The molten water-based of the present invention is very strong, and molten 95% water also can be as clear as crystal, does not have precipitation, and is not muddy.This glue good dispersity is beneficial to spray method and executes this glue, and it is required also to adapt to other different size applicators.This Phenol aldehyde resin is in manufacturing processed, and the temperature of reaction of requirement is low, easily grasp, and cheap.
Embodiment: phenol is put into reactor for 100 parts, start agitator, hydrated barta is mixed well with hot water for 5 parts, temperature is raised to 43 ℃, with 10 minutes hydrated barta is evenly added in the retort, 45 ℃ of insulations 30 minutes, add 80 parts in formaldehyde, be warmed up to 45 ℃, this temperature insulation 2 hours, in 40 minutes, temperature is raised to 75 ℃, be incubated 2 hours then, the beginning viscosimetric is when viscosity reaches 8～10 centipoises, logical cold water is cooled to 40 ℃ of blowings, promptly obtains product.(raw material ratio is a weight ratio in the example)
Claims (4)
