The invention discloses a method for preparing linear thermistor slurry with negative temperature coefficient, which comprises the following steps: 1) burdening barium carbonate and lead tetraoxide according to mole ratio of 1: 0.34-0.4, performing high-speed ball-milling mixing, drying and sieving, insulating for 8-12 hours at 750-850 DEG C to obtain a reactant, performing ball milling on the reactant for standby; 2) burdening barium carbonate and bismuth trioxide according to mol ratio of 1: 0.5-0.53, then performing high-speed ball-milling mixing, drying and sieving, insulating for 8-12 hours at 700-850 DEG C to obtain a reactant, performing ball milling on the reactant for standby; and 3)uniformly mixing the material obtained in the last two steps according to mass ratio of 1: 0.05-0.8, and then adding a certain amount of organic carrier for rolling to obtain a slurry. According to the invention, the linear NTC thick membrane slurry used for screen printing can be developed, and a slurry formula with high resistance temperature coefficient (TCR) and low sheet resistance can be obtained, TCR can reach -1000--7000ppm / DEG C, the sheet resistance scope is 5 omega / squre-4K omega / square, and the a technical scheme provided by the invention has good expansibility.

ActiveCN112159607AImprove cohesive strengthHigh peel strengthNon-macromolecular adhesive additivesRoof covering using flexible materialsPolymer scienceOrganosolv
The invention discloses a butyl adhesive tape primer for a roof TPO waterproof roll, and application thereof. The application comprises the following steps: applying the primer to a construction matrix, and then adhering a butyl adhesive tape to the surface of the primer. Raw materials of the butyl rubber tape comprise a first butyl rubber matrix and an oxide, and the oxide is selected from one ora combination of more of manganese dioxide, zinc oxide, lead dioxide and lead tetroxide; the primer comprises, by weight: 8-25% of a second butyl rubber matrix, 1-15% of a second tackifying resin, 0.2-2% of a cross-linking agent, and 65-85% of an organic solvent; and the cross-linking agent is p-benzoquinone dioxime, The primer disclosed by the invention has a synergistic effect with conventionaloxide-containing butyl rubber after construction, so that the peel strength, persistent adhesion, water resistance and the like of the butyl rubber tape can be remarkably improved, and particularly,the problem that the performance of the butyl rubber tape is seriously reduced due to long-term soaking of concrete can be solved.
