Embodiment 1

[0018] A method for enhancing the coating performance of a fir primer. Before coating, a reinforcing agent with a mass fraction of 5.0% is added to the primer to process a modified emulsion. The reinforcing agent is made of the following components in parts by weight: poly 20 parts of acrylamide, 2.8 parts of cellulose ether, 1.5 parts of tetrabutylammonium bromide, 0.4 parts of calcium carbonate, 0.2 parts of sodium lauryl sulfate, 0.5 parts of maleic anhydride, 2.0 parts of ethyl acetate, potassium permanganate 0.10 part, 50 parts of ethanol, mass concentration are 20 parts of sodium bicarbonate aqueous solution of 16%, and processing process comprises the following steps:

[0019] (1) Pour the primer into the reaction kettle, add a mixed solvent accounting for 8% of the primer volume fraction and start stirring, and gradually increase the temperature at a rate of 0.3°C / min. When the temperature reaches 43°C, stop heating and add the strengthening agent, stirred rapidly for ...

Embodiment 2

[0028] A method for enhancing the coating performance of Chinese fir primer. Before coating, a reinforcing agent with a mass fraction of 5.5% is added to the primer to process a modified emulsion. The reinforcing agent is made of the following components in parts by weight: poly 21 parts of acrylamide, 2.9 parts of cellulose ether, 1.6 parts of tetrabutylammonium bromide, 0.5 parts of calcium carbonate, 0.25 parts of sodium lauryl sulfate, 0.6 parts of maleic anhydride, 2.2 parts of ethyl acetate, potassium permanganate 0.11 part, 55 parts of ethanol, mass concentration are 23 parts of aqueous sodium bicarbonate solution of 18%, and the processing process comprises the following steps:

[0029] (1) Pour the primer into the reaction kettle, add a mixed solvent accounting for 9% of the primer volume fraction and start stirring, and gradually increase the temperature at a rate of 0.35°C / min. When the temperature reaches 44°C, stop heating and add the strengthening agent, stirred ...

Embodiment 3

[0038] A method for enhancing the coating performance of fir primer. Before coating, add a strengthening agent with a mass fraction of 6.0% to the primer to process to obtain a modified emulsion. The strengthening agent is made of the following components in parts by weight: poly 23 parts of acrylamide, 3.0 parts of cellulose ether, 1.8 parts of tetrabutylammonium bromide, 0.6 parts of calcium carbonate, 0.3 parts of sodium lauryl sulfate, 0.7 parts of maleic anhydride, 2.5 parts of ethyl acetate, potassium permanganate 0.12 parts, 60 parts of ethanol, mass concentration are 25 parts of aqueous sodium bicarbonate solution of 20%, and the processing process comprises the following steps:

[0039] (1) Pour the primer into the reaction kettle, add a mixed solvent accounting for 10% of the primer volume fraction and start stirring, and gradually heat up at a speed of 0.4°C / min. When the temperature reaches 45°C, stop heating and add the strengthening agent, stirred rapidly for 50 ...

Abstract

The invention belongs to the technical field of wood performance, and discloses a method used for enhancing cunninghamia lanceolata priming paint coating performance. According to the method, before coating, by mass, 5.0 to 6.0% of an enhancer is added into a priming paint for processing so as to obtain a modified emulsion; the modified emulsion obtained through mixing and processing of the enhancer possesses important effect in enhancing of the bonding force of cunninghamia lanceolata, is capable of improving cunninghamia lanceolata wooden structure, enhancing the permeability and the effectof the modified emulsion on cunninghamia lanceolata timber, realizing priming paint one time film forming, achieving high fullness and excellent surface effect; after paint film forming, because of the modifying effect of the enhancer, cunninghamia lanceolata sufaces are capable of providing paint film with constant rigid support, cunninghamia lanceolata deformation resistance is improved, generation of cracking is avoided, the bonding degree of cunninghamia lanceolata surfaces with the priming paint is improved, paint film clunging force is increased naturally, priming paint using amount is reduced, curing time after coating is shortened, processing cost is reduced, processing time is shortened, energy is saved, efficiency is high, the method is green and safe, and no secondary pollutionis caused.

Description

technical field [0001] The invention belongs to the technical field of wood performance research, and in particular relates to a method for enhancing the coating performance of fir primer. Background technique [0002] Chinese fir, also known as: sand wood, sand tree, etc., belongs to Pinaceae, fir tree, up to 30 meters, diameter at breast height of 2.5-3 meters; bark grayish brown; winter buds nearly round, male cones conical, female cones Single, ovoid cone, 2.5-5 cm long, 3-4 cm in diameter; seeds are flat, covered with seed scales, long ovate or oblong, flowering in April, and cones mature in late October. It is mainly used for expelling wind and relieving pain, dissipating blood stasis and stopping bleeding. Chinese fir wood is yellowish white, sometimes the heartwood is light reddish brown, soft, delicate, fragrant, straight texture, easy to process, specific gravity 0.38, strong corrosion resistance, not eaten by termites. For construction, bridges, shipbuilding, or...
