Abstract
The invention discloses the modifier and addition agent of trialdehyde resin glue to reduce free aldehyde and cost. The method comprises the following steps: using seed capsule as raw material, inflating the seed capsule, dissolving, activating, modifying, cross bonding, grafting, adjusting viscosity, and getting the product. The invention has the advantages of decreasing odour in workplace, reducing cost, and improving bonding strength. The invention can be uses as copolymerization modifier and increment removing aldehyde addition agent.
Description
Technical field
The invention belongs to fine chemical product, tackiness agent, tackiness agent additive and copolymeric material.Materials chemistry attribute of the present invention belongs to natural high molecular substance.Product of the present invention is a kind of environmentfriendly products, can reduce the free formaldehyde of three aldehydes resin glue (urea-formaldehyde resin, melamine formaldehyde resin and resol), and the formaldehyde that reduces the toxic property of wood-based plate discharges.
Background technology
Present three urea formaldehyde glue are that the artificial board production that the whole world is generally used sticks with glue agent, so far there is not a kind of cost performance to replace three-aldehyde glue fully than the better structure glue of three-aldehyde glue, Japan uses isocyanate glue to replace urea-formaldehyde glue, and price is 4-8 a times of urea-formaldehyde glue, can only use among a small circle.And the present invention can be significantly reduced to this and do not influence performance.Domestic existing de-aldehyde agent kind exists cost height or weak effect or influences the problem of sheet material physical index.Product of the present invention has active hydroxyl, amino, aldehyde radical, carboxyl, ester bond isopolarity and nonpolar reactive group, can produce crosslinked and Chemical bond to wood-cellulose, tackiness agent when the hot pressing, and some active group can with methylolurea, formaldehyde, resin under certain condition (temperature, pH value) and catalyst action, copolymerization or crosslinked takes place, improve the molecular weight and the cohesive strength of glue, improve the performance of glue, and great amount of hydroxy group wherein can play the tackiness agent function of stabilizer, make polymerization process steady, product director's storage period, bonding strength obviously improves.
Summary of the invention
The invention discloses a kind of three urea formaldehyde glue copolymerizing modifier, the aldehyde adhesion promoting additive falls, in order to reduce the free aldehyde of three urea formaldehyde glue (urea-formaldehyde resin, melamine-formaldehyde resin, phenolic resin) and wood-based plate, reduce production costs, improve bonding strength.The present invention is a raw material with plant species skin (can be factory's byproduct or waste), through swollen, activation, (enzymolysis) modification, grafting, crosslinked, adjust viscosity of technology and form.
Description of drawings
This accompanying drawing is a process flow sheet of the present invention.
Annotate: 1,2,3,4,5 road technologies can the series, parallel selection use flexibly by client's specific requirement.
Embodiment
The present invention with the plant species skin be raw material (plant micromicro to be factory's byproduct or waste) through swollen, activation (or enzymolysis, oxidative degradation), modification, grafting, crosslinked, adjust technological processs such as viscosity and flowability.Destroy one dimension, two dimension, three-dimensional, four-dimensional structure, crystallinity that starting material have external resistance, its active group is exposed or degraded, active group is activated, modification, grafting, improves adhesivity, take crosslinked mode to improve cohesive strength and water tolerance, form by viscosity modifier adjustment flowability, adding preservative agent.
The present invention early stage swollen, degraded, activating process are identical, and later stage grafting, technology such as crosslinked are variable, can be made into series product to adapt to the needs of different user.
Applicating example of the present invention:
Example one, low-cost prescription (being applicable to low-cost multi-ply wood glue) plant species skin 100-400, S-WAT 6-40.Ammonium chloride 10-30, catalyzer 1-10, PVA5-20, linking agent 1-3, CMC2-5, organic acid 1-3, thiocarbamide 1-2, trolamine-an amount of, phenols-an amount of, alkali lye-an amount of, hydroformylation agent 5-30, amination agent 20-80, tackifier 8-15, water-an amount of.
Claims (4)
1, aldehyde properties-correcting agent, additive fall in a kind of three urea formaldehyde glue (urea-formaldehyde resin adhesive, melamine-formaldehyde resin adhesive, Phenol aldehyde resin).
It is factory's byproduct as this raw material of raw material that the present invention uses the plant species skin, and price is very low.
Technological process is the immersion swollen, activation, modification, crosslinked, grafting, adjustment flowability and viscosity of technology process form, invention is series product, can require according to user's difference and technological process be accepted or rejected, change the kind of Similar types of materials, wherein be modified as oxidation modification, ammoniation modified, adhesiveness increasing and modifying, crosslinked and grafting, use different kinds, can also strengthen de-aldehyde agent, fluidity improver etc. according to user's needs.
2, according to claim, aldehyde properties-correcting agent falls in three urea formaldehyde glue, additive is characterized in that using the plant species skin as raw material, and this all micromicro to be to be factory's tankage, and cost is low.
3, according to claim 1, it is characterized in that production technique, comprise that swollen, alkali are molten, oxidation modification, amination modified, grafting, crosslinked with several linking agents, with the tackifier tackify, improve mobile and be medium with water.
4, according to claim 1, can before polycondensation, add the formation modification by copolymerization in the product formulation glue process of the present invention, also can add the blending and modifying increment in post-processing stages.
