Description
Technical field
The invention provides a kind of tackiness agent connected for timber, particularly relate to a kind of wood adhesive with resistance to elevated temperatures and preparation method thereof, belong to the adhesive technology field.
Background technology
Tackiness agent is the Modern Fine Chemical Industry product, and since 21st century, tackiness agent and adhesive technology have demonstrated incomparable vigor and vitality, its importance grows with each passing day, and its practicality attracts people's attention, and its popularity is promising, application be should widely popularize, considerable economic benefit and social benefit created.In American-European countries, the rate of growth of tackiness agent is higher than the rate of growth of gross national product, and average growth rate is 3% left and right.World's tackiness agent annual turnover surpasses 1,000 ten thousand tons at present, and global synthetic adhesive sales volume is over 26,000,000,000 dollars.
Timber is by various cellularities: test-tube baby, xylon are the major portions of cell, and the character of timber is produced to conclusive impact.Timber has expansibility and contractibility, and because of the Swelling and contraction that moisture absorption or oven dry occur, because the tangent plane direction is different, the rate of expansion of tangential direction is 2 times of left and right of radial direction rate of expansion; Length direction is 1/10 left and right of tangential direction.
The mechanism of bonding wood is to rely on cast setting effect and Intermolecular Forces to occur bonding.But that play a major role or intermolecular physics or chemical action.The characteristics that wood adhesive should possess: (1) tackiness agent should have polarity; (2) tackiness agent should have suitable wettability; (3) tackiness agent should have suitable potential of hydrogen; (4) tackiness agent should have suitable molecular weight.
Starch is the very abundant organic compound of occurring in nature content, has wide material sources, the advantage such as cheap, biodegradable, renewable.Scarcity day by day along with oil and coal resources, how from depth & wideth Application and Development starch, become the research topic of Chinese scholars common concern.Starch pasting or oxidation modification are used existing history for a long time as tackiness agent, still, because bonding strength is little and the shortcoming such as poor water resistance, its range of application are greatly limited.Particularly, in the wood adhesive industry, seldom with starch, as raw material, develop wood adhesive.
