Embodiment 1
[0039] Example 1: High-weight flame-retardant and waterproof carton.
[0041] (1) Mix 25kg of raw starch, 8kg of caustic soda and 250kg of water, and stir for 30-50 minutes to obtain the cooked pulp intermediate.
[0042] (2) Mix 250kg of raw starch, 4.3kg of borax, 8kg of modified chlorinated paraffin, 8kg of modified silicon dioxide, 5kg of sodiumphosphate, 5kg of halogen-free flame retardant with 625kg of water, and stir for 10 minutes.
[0043] (3) Keep stirring in step (2), and slowly add the cooked pulp intermediate in step (1) into step (2) until it is evenly stirred to obtain the starch adhesive.
[0044] Preparation method of flame retardant liquid: mix 15kg of sodium 12-alkylsulfonate, 20kg of modified chlorinated paraffin, 18kg of modified silicon dioxide, 10kg of sodiumphosphate, 25kg of halogen-free flame retardant and 140kg of water, and stir for 20~ 30 minutes will do.

Abstract
A preparation method of a flame-retardant waterproof high-gram-weight paper board is characterized by including the following steps that 1, two layers of 200 g / <2> craft paper are used and two layers of 175 g / m<2> liner paper are used, wherein the two layers of liner paper adhere to each other through starchadhesive on the same single facer to generate composite paper of 400 g / m<2>, and then the composite paper and the two layers of 200 g / m<2> craft paper adhere to each other through starchadhesive on a double facer to be a 900 g / m<2> paper board through drying; 2, the front and back faces of the 900 g / m<2> paper board are painted with flame-retardant coating respectively and dried through a hot plate of a corrugated board line to form the high-gram-weight waterproof flame-retardant paper board. The whole high-gram-weight flame-retardant waterproof paper board is completed on the corrugated board line all the way.
Description
technical field [0001] The invention relates to a method for preparing a high-gram-weight cardboard with flame-retardant performance and waterproof performance. Background technique [0002] Because corrugated cardboard factories basically do not have their own paper mills, they cannot meet the needs of matching paper according to their own paper specifications. They can only meet production needs through negotiation with paper mills. In the market, the high-quantity corrugated paper sold is generally 200-300 g / m 2 Imported high-gram-weight corrugated paper generally does not exceed 440 g / m 2 . For some high-weight paper specifications for special purposes, corrugated board mills can only turn to paper mills for help. [0003] One of the flame-retardant methods for flame-retardant and waterproof corrugated boxes is to minimize the supply of oxygen during combustion. If the corrugated corrugated paper composite technology is still used in the middle of the new carton, it ...
