Abstract

The invention discloses a water glass-based multiple-effect wood adhesive and a preparation method thereof. The water glass-based multiple-effect wood adhesive comprises the following materials by weight parts: 100 parts of water glass, 10-20 parts of ammonium salt modified acrylate emulsion, 4-8 parts of magnesium myristate, 1-2 parts of a silane coupling agent, 5-10 parts of tetrapod-like zinc oxide whiskers, 1-3 parts of xanthan gum, 3-8 parts of silicon dioxide coated ammonium polyphosphate, 3-5 parts of molybdenum oxide, 10-30 parts of water, and 6-12 parts of silica micro-powder. The preparation method comprises the two steps: preparation of silicon dioxide coated ammonium polyphosphate and preparation of the water glass-based adhesive. The water glass-based multiple-effect wood adhesive has environment-friendly and non-poisonous effects, and has the functions of inflaming retarding, smoke suppression, bacteria prevention, sound absorption, corrosion prevention, water proofing and the like; the preparation method is simple and convenient, and is easy in industrialization.

Description

A kind of water glass Quito effect based Wood Adhesives and preparation method thereof
Technical field
The present invention relates to based Wood Adhesives field, be specially a kind of water glass Quito effect based Wood Adhesives and preparation method thereof.
Background technology
Traditional timber sizing agent only has binding function usually, and cause the preparation of functionalization composite wooden material often to need first to carry out the multi task process such as fire-retardant, anticorrosion to timber, technique is loaded down with trivial details, low effort.Modern the growing of wood-based panel industry makes it more and more higher to the requirement of sizing agent, and except having high adhesion energy, the multiple-effect wood sizing agent had without aldehyde, the performance such as fire-retardant, antibacterial, anticorrosion is just receiving more concern.
Summary of the invention
Technical problem solved by the invention is to provide a kind of water glass Quito to imitate based Wood Adhesives, to solve the shortcoming in above-mentioned background technology.
Technical problem solved by the invention realizes by the following technical solutions:
A kind of water glass Quito effect based Wood Adhesives, comprises the raw material of following weight part:
Water glass: 100 parts;
Ammonium salt modified acrylate emulsion: 10-20 part;
Myristic acid magnesium: 4-8 part;
Silane coupling agent: 1-2 part;
Four acicular type zinc oxide crystal whisker: 5-10 part;
Xanthan gum: 1-3 part;
Coated with silica ammonium polyphosphate: 3-8 part;
Molybdenum oxide: 3-5 part;
Water: 10-30 part;
Silicon powder: 6-12 part;
Its concrete preparation method's step is:
1) first prepare coated with silica ammonium polyphosphate: ammonium polyphosphate powder is immersed 24h in silicon sol, then mixture is dry, pulverize, levigate, just obtain described coated with silica ammonium polyphosphate.
2) slowly join in 100 parts of water glass by 10-20 part ammonium salt modified acrylate emulsion, hand operated mixing makes the two mix.Then 4-8 part myristic acid magnesium, 1-2 part silane coupling agent, 5-10 part four acicular type zinc oxide crystal whisker is added successively, after stirring under rotating speed is 800r/min rotating speed, add 1-3 part xanthan gum, 3-8 part coated with silica ammonium polyphosphate, 3-5 part molybdenum oxide and 10-30 part water again, dispersed with stirring 30-60min under rotating speed is 800r/min rotating speed.Finally add 6-12 part silicon powder, stir.
Know-why of the present invention is: ammonium salt modified acrylate emulsion has the advantages that snappiness is high, sticking power is good, it is mixed with water glass, can realize reducing the fragility of water glass adhesive and strengthening the object of splicing power; Four acicular type zinc oxide crystal whisker has wear-resisting, enhancing, noise reduction, suction ripple, the outstanding properties such as antistatic, antibacterial, anti-aging; Silicon powder has fire-resistant, anticorrosion, waterproof, the function such as impervious; Molybdenum oxide and coated with silica ammonium polyphosphate have smoke-inhibiting flame retardant effect, and coated with silica ammonium polyphosphate can prevent fire retardant in use to run off, and plays permanent flame retardant effect; Myristic acid magnesium is a kind of higher fatty acid salt, can capture the sodium ion in water glass, plays the effect strengthening sizing agent water resistance; Meanwhile, between silicon, magnesium, phosphorus, molybdenum, zinc plasma, can synergistic effect be produced, improve the fire-retardant fireproof performance of sizing agent further; Xanthan gum has emulsification, thickening, stable effect, contributes to the infiltration of system and stablizes.Thus, above combined system can obtain having environment friendly aldehyde-free, fire-retardant, press down cigarette, antibacterial, sound absorption, many effects such as anticorrosion, water-fast in the based Wood Adhesives of one.
Beneficial effect: all abundance, excellent property, nontoxic such as the present invention's main ingredient used water glass, acrylic ester emulsion, silicon powder, four acicular type zinc oxide crystal whisker, myristic acid magnesium, xanthan gum, ensure that high-performance and the environment friendly aldehyde-free of sizing agent.In the present invention based Wood Adhesives have concurrently environmental protection, fire-retardant, press down cigarette, antibacterial, sound absorption, the effect such as anticorrosion, water-fast, and preparation technology is simple, easy industrialization, cleanliness without any pollution.Use multiple-effect wood sizing agent of the present invention a step can realize having multi-functional all kinds of wood-based panel product manufacture.
Embodiment
The technique means realized to make the present invention, creation characteristic, reaching object and effect is easy to understand, below in conjunction with specific embodiment, setting forth the present invention further.
